Ancient astrologers believed that great people are born under this star. However, Regulus has a dual effect on the horoscope. Most often, its impact brings huge life's blessings and great success in all endeavors, but it may happen that it will bring grief.

The astrological influence of Regulus on the fate of a person is similar to the influence of Jupiter, Saturn and Mars. Connecting with Jupiter, Regulus helps his ward to achieve power, wealth and success, but a person's life could end either in a violent death or a serious illness. Combined with Saturn, Regulus has an even more beneficial effect on fate, as it does not portend a painful death. Regulus in conjunction with the Sun promises power and the fulfillment of almost all desires. Modern astrologers claim that Regulus helps his ward to show will, become bold, stubborn and noble, opens up scope for the manifestation of creative abilities.

The positive influence of the star Regulus on the horoscope

Especially favorable is the presence of a star in the 10th house of the horoscope. Her influence manifests itself as success in various endeavors, influence in society, a fast-moving career, and great wealth. Success in business, state and military affairs, connections with respected famous people accompany those who are patronized by Regulus. The star helps to win, to become the best in all matters, if a person, using his leadership qualities, remains generous, shows nobility and does not seek to use his power and strength too much. For a person who has Regulus, the career of a military man, politician, public figure, as well as a banker, lawyer or clergyman is especially favorable.

Negative aspects of the manifestation of the star Regulus in the horoscope

Regulus often causes a desire to assert oneself, regardless of others, a desire to dominate, to show oneself in a more favorable light, despite adverse consequences. Often, the influence of a star makes their wards clearly demonstrate the strength that is present in abundance in the character of a person with a strong Regulus in the horoscope. Such people are also characterized by inattention to changes in the current situation, unwillingness to change the tactics of behavior, regardless of the fact that the situation may end in trouble or even disaster for them.

Great success awaits a person whose Regulus is manifested in his birth chart, but sometimes this success can be achieved if he passes the test of revenge. Such a test consists in the fact that a person with Regulus in the horoscope should try to avoid revenge, otherwise he may lose the received power, position and influence in society, a loss of wealth is possible. In order to smooth out these negative manifestations of the influence of a star, you need to defeat yourself, overcoming manifestations of arrogance, attacks of pride in yourself, not considering yourself better than others.

In general, Regulus, the description of which was given above, is happy Star which gives power, high position, considerable influence in society, brings honors, glory and success to its wards. And at the same time, it requires them to have appropriate ambitions, a global approach to the main issues, and global scope in achievements. The influence of the star makes it possible to achieve brilliant results for those who have chosen for themselves military service, big politics, for major managers and leaders, professional athletes. Star Regulus gives good luck to people with ideas of a global scale, characterized by a breadth of views and a non-standard approach to solving issues.

Every year around August 22-23, the Sun passes 30 degrees Leo. One of the most beautiful and happiest stars in the sky is now projected onto this degree of the ecliptic - this is Alpha of the constellation Leo - REGULUS.

The strong influence of this star can be experienced by those who were born in the area - August 22, February 19, November 22, May 21, April 20, December 21.

Regulus is a blue star of the first magnitude, one of the 20 brightest stars in our sky! The exact conjunction of the Sun and Regula will occur on August 23, 2006 at 4:17 GMT at 29°54" 59" Leo

Since the star Regulus is located exactly on the ecliptic, its sunrises and sunsets will always occur at all latitudes (except for the polar regions) on the same days.

Its true heliacal rise (rise with the Sun) is on August 22, and its acronic rise (rise at sunset) is around February 19.

Everyone who was born in the area of ​​​​these dates will have Regulus included (in one way or another) in their cards.

Regulus is one of the great historical stars in the sky. According to the ancient Persian astrologers, Regulus is a royal star - one of the four main stars of the sky, under which the powers that be are born. Four and a half thousand years ago, Regulus was projected to the northern point of the ecliptic, where the alpha of Orion, the orange giant Betelgeuse, is now located.

The Persians considered Regulus the Guardian of the North, who was associated with their mythical king Feridun, who once ruled, in their mythology, everything known world. He was a good and great king, whose origin was similar to the Greek Zeus. Like Zeus, he was brought up separately from his family, was fed by a sacred cow, and when he matured, he claimed his right to the throne in a great struggle. His image is also similar to the Egyptian Osiris: he taught, brought peace and civilization, gave laws to his people. In his old age, he decided to divide his great kingdom among his three sons. The two eldest sons attacked their youngest and killed him in order to take possession of his lands, and this act so saddened Feridun that he took revenge on his eldest sons. The ensuing battle was the end of his kingdom and the end of the happy days of Feridun.

A person with a pronounced Regulus in the birth chart can achieve great success in life. In Brady's opinion, this success can only be achieved through the test of REVENGE. If a Regulus person humiliates himself to the point of revenge, he will lose power and his position in society. And the higher Regulus raises a person, the more he must beware of revenge.

In general, this is a very powerful and happy star, giving its wards - power, charisma, fame, success, honors, high position and a huge influence on the world around. This is especially true for those who are realized in the military field, in sports, politics, and the management of large economic structures and enterprises. This star loves a big approach with a global reach and ambitions to match. Regulus will give the greatest luck to those daredevils who have a broad outlook, global thinking and world-class concepts.

Regulus can be turned on for everyone in whose personal horoscopes important points (especially the corners of the horoscope !!! and luminaries) fall into the 30th degrees of Leo (especially !!!), Aquarius, Taurus, Scorpio, Aries, Sagittarius.

Everyone who was born in the area has the sun in these degrees - August 22, February 19, November 22, May 21, April 20, December 21.

Regulus(Regulus, lat. "king"), Leo's Heart (lat. Cor Leonis), Kalb (Kalb, Arabic. "heart") - a fixed star, 32 alpha Leo. Apparent stellar magnitude 1.35 m . Spectral class B7 V. R. - a system of four stars; two main components 1.4m (class B) and 7.7m (class G) are located at an angular distance of 176.9 "from each other. The third component is a faint star 13m, probably a white dwarf. The distance from R. to the Sun is 25.6 pc. The luminosity of R. - 148 luminosities of the Sun, surface temperature - about 14 000 ° K. Astronomical position of R. for 2000.0: AR=10h08.4m; D= +11°58"; Long= 149°49"45"; Lat = +00°27"53". In the drawing of the constellation R. is located on the heart of Leo.

According to the ancient Persian astrological legend, in ancient times, R. marked the point of the summer solstice and was called the Guardian of the North (see Guardians of Heaven).

According to the tradition coming from Ptolemy, R. acts like Mars and Jupiter. Kefer, considering this influence favorable, notes that R., being manifested in the tenth house, is associated with the desire for power, rule, wealth, and influence. R. in conjunction with Jupiter has the highest favorable influence, indicates a career, but death will be violent or after a long illness. In conjunction with Saturn, R. has a similar meaning, but portends a non-violent death. R. in conjunction with ASC portends power and honors due to his own merits.

According to F. Velichko, R. forms an original, strongly deviating from the ordinary life path with a shiny or at least unusual top, but at the same time R. does not guarantee against the danger of failures and falls.

According to the observations of Ebertin and Hoffman, R. indicates nobility, sincerity, openness, courage. On the ASC, this star gives courage and openness, especially when conjunct the Sun, Moon, Jupiter or Mercury. R. on MC promotes a career and the achievement of a high social position, far superior to the environment from which the person came out. R. gives connections with the authorities, with respected and famous people, if the card as a whole gives such an opportunity. The conjunction of R. with Jupiter is one of the best configurations for success, wealth and power fall, as they say, like snow on the head. For a person with a strong R. in the natal chart, a military career is most likely, but there may also be a career as a lawyer, banker, clergyman, etc., especially if R. connects with one of the luminaries or with a favorable planet.

In addition to the traditional one, Devor gives two more options for correlating R. with planetary influences: Mars and the Sun-Uranus. According to Devor, this star indicates a propensity for destruction, military honors ending in defeat; generosity, generosity, tolerance; independence and high spirituality. R. on ASC portends fame and fortune, but also susceptibility to various diseases. R. on MC indicates a high position in the government and military successes. In conjunction with the Sun, Moon or Jupiter - honors and exceptional luck.

Rigor notes that the impact of R. is not always only beneficial. The benefits given by R. will most often be short-lived; R. pushes to scandalous acts, manifestations of violence. Failures and lost greatness are often associated with R. People with R. manifested in the horoscope need to be careful, because otherwise the recognition and position they have achieved may be replaced by a complete collapse. Usually people in whose horoscope there are connections with Regulus leave a mark in the memory of posterity, but there is always a danger that the public will be disappointed in them. This is especially true in cases where the radix also has a connection of some planet with Alphard.

In the Avestan tradition, the servants of R. are the Sun and Jupiter (in some sources also Mars). P. Globa notes that this "royal star" gives power, strength, honors, fame, fame, wealth, luck, organizational skills, impressiveness. R. on ASC or in conjunction with planets near ASC gives respect and popularity in the early years, early fame. When R. is combined with evil planets, this fame will be scandalous. R. on MC gives honor, respect and makes a person famous; on DSC or in conjunction with planets in the 7th house gives public popularity, fame, respectable marriage at the end of life. In medical astrology, R. is a beneficent star that strengthens the work of the heart.

In the theory of systemic interpretation of stars by D. Kutalev, R. as the alpha of Leo correlates with the element of Fire at the first, lowest level of manifestation, and as a representative of the spectral class B is associated with Saturn. According to this theory, R. gives a constant desire to assert oneself at the expense of others, to dominate others, to shine, regardless of the consequences. R. is associated with an unequivocal demonstration of the power that this star provides in abundance. However, people with strong R. in the horoscope are also characterized by disregard for the changing situation, which can end badly for them.

In lunar astrology, R. is associated with the 10th station of the Moon.

Regulus or alpha constellation Leo(α Leo) - the main and brightest star in a large and expressive zodiac constellation. Regulus lies almost exactly on the ecliptic, which means that every August the path of the Sun passes through it. This star is also often covered by the Moon. In the spring, when there are few bright stars in the sky, only three stars - Regulus, Spica and Arcturus - clearly stand out in the sky among others. With a magnitude of 1.35 m, Regulus is considered the last of the stars of the first magnitude and takes 21st place in the list of the brightest stars in the night sky.

The name Regulus (from Latin regulus) is translated as "king" or "prince". Ptolemy, one of the greatest astronomers of the ancient world, called Regulus βασιλίσκος (Basilisk), which again means “king” in Greek. The "royal" star was called Regulus and Arab astronomers. It is obvious that the name of the star is very ancient; probably its origin is due to the Babylonians or even the ancient Sumerians.

It is difficult to say why Regulus was considered a "royal" star in the past, but its importance for the ancients is undeniable (it is not for nothing that the word regulate). And what do we know about alpha Leo today? Precise methods of observation made it possible to find out a lot of interesting things about this star.

Brief description of Regula

Regulus is a hot, bluish-white main sequence star belonging to the spectral type B7V. The distance to Alpha Leo is measured very accurately by the Hipparcos satellite and is 77.6 light years. Regulus exceeds the Sun by 3.5 times in mass, almost 4 times in diameter (see below for the shape and size of Regulus) and 141 times in luminosity.

Unlike the Sun, Regulus is a multiple star. At an angular distance of 176 ″ from it (this is almost 3 arc minutes), the Regula satellite is already visible in small telescopes - an orange star 8.11 m. In the catalog of Henry Draper, it is designated as HD 87884, and we will call it Regulus V. The stars are separated by at least 4200 AU. e., which is 100 times the distance from the Sun to Pluto. Still, this is much less than the average distance between stars in the galaxy, and general movement in space, Regulus and his companion suggests that they are physically connected. In this case, the period of revolution of stars around a common center of mass is at least 130,000 years (according to Jim Kahler).

Regulus B belongs to the orange main sequence stars. It is colder and lighter than the Sun. The spectral class of the star is K2V, it emits three times less light than our star. According to its characteristics, Regulus B resembles the star α Centauri B, the middle component in the Alpha and Proxima Centauri systems.

Careful observations have shown that Regulus B is itself a double star.. The second component, a red asterisk 13.1 m , is located a few arc seconds from Regulus V. For the period from 1867 to 1943. it has changed position from 4.0″ to 2.5″, but has not been measured in the last 60+ years. Judging by the brightness, the star Regulus C should belong to the spectral class M4V. This is a typical red dwarf.

Components B and C are separated by at least 97 astronomical units (AU), and the period of revolution around a common center of mass is at least 880 years. Looking from this small double at Regulus A, the observer would see it as a star, only four times brighter than the full moon.

But the components in the Alpha Leo system are not exhausted on this! In 2008, another satellite of Regulus, Regulus D, was discovered, orbiting the main white star with a period of only 40 days. This discovery intrigued scientists, since Regulus D is a dense and hot white dwarf with an anomalously low mass of about 0.3 solar masses. According to all the laws of stellar evolution, the mass of a white dwarf cannot be lower than 0.55 solar masses. Due to its proximity to Regulus and the large difference in brightness, it cannot be observed directly with any telescope. However, its presence was discovered as a result of subtle spectroscopic observations of Regulus. The discovered satellite can probably explain interesting feature the main star - its huge speed of rotation. And at the same time shed light on the lack of own mass.

Why does Regulus spin like a top?

It has long been known that Regulus A, the main star of the system, rotates around its axis very quickly. Precise measurements show that the star's equatorial rotation speed reaches more than 300 km/s. This is 150 times faster than the speed of rotation of the Sun! Due to the huge speed of rotation, centrifugal forces tend to pull the star apart (if the star were only 14% faster, it would inevitably fall apart), and astronomers knew that from the side Regulus should not look like a sphere, but rather like a disk, flattened to the poles.

Since 2005, astronomers have been observing Regulus using the interferometry technique. This technique allows recreate the image of the disk of a star from simultaneous observations at several telescopes located at a considerable distance from each other. It turned out that Regulus is indeed strongly flattened, its equatorial diameter is 32% larger than the polar one. The axis of rotation of the star is perpendicular to our line of sight. In other words, we see Regulus from the edge, like an elongated ellipse. The brightness of this ellipse is unevenly distributed. Due to gravitational darkening, Regulus is dimmer at the equator; its temperature in this region is about 9500 K. At the poles, the star, on the contrary, is hotter and shines more intensely. The temperature of these areas is 15400 degrees Kelvin.

But why is Regulus spinning so fast?

Until very recently, there was no satisfactory explanation for this. But after 2008, when the already mentioned white dwarf, Regulus D, was discovered in the star system, an international group of astronomers proposed a mechanism for spinning the star in the article “Past and future history Regula (The Past and Future History of Regulus).

As you know, white dwarfs are the end products of the evolution of relatively low-mass stars, which include the Sun, Regulus or, for example, Sirius. This means that the Regulus satellite was once a normal star (slightly larger, more massive and much brighter than Regulus itself), then turned into a red giant, and then, dropping an extended shell, into a compact and superdense white dwarf. So, being at the stage of a red giant, the satellite star Regula filled the so-called. the Roche cavity and, as a result of the action of tidal forces, began to transfer its substance to Regulus. A plasma accretion disk formed around Regulus, the substance of this disk transferred the moment of rotation to the star, thereby spinning it up to tremendous speed.

There are pitfalls in this hypothesis (in particular, those associated with the upper limit of the mass of the incident matter: according to the theory, if more than 10% of its mass fell on a star, then the receiving star must inevitably collapse under the action of centrifugal forces), but the explanation itself very beautiful.

How old is Regulus?

The discovery of a white dwarf in the Alpha Leo system raised another question: how old is Regulus? Previously, it was believed that this is a very young star, 50-100 years old, or at most 200 million years old. But this period is clearly insufficient for the evolution of the satellite star Regula and its transformation into a white dwarf.

Calculations show that for the evolution of Regulus D, the age of the system must be at least 900 million years, which in turn raises the question of why Regulus himself did not evolve during this period? After all, such hot stars burn hydrogen in the core much faster than the Sun, and therefore live only a few hundred million years ...

And that’s why it didn’t evolve, the authors of the work on the history of the star believe, that managed to literally rejuvenate as a result of pulling a significant amount of matter from the outer layers of the satellite star - a substance rich in hydrogen!

How to find Regulus in the sky

In conclusion, let's say a few words about how to find Regulus in the sky. We have already mentioned that Alpha Leo is the brightest star in this constellation and one of the brightest stars in the sky. Regulus is the lower right star of the four stars of the constellation Leo, forming a large trapezoid, clearly visible in the sky from February to April. At the same time, Regulus is the handle of the Sickle, a well-known asterism that looks like a mirrored question mark. On ancient star maps, the torso of the Lion was drawn in place of the trapezoid, and the "Sickle" was the head of the animal.

Regulus is the brightest star in the constellation Leo. Together with the stars η Leo, γ Leo (Algieba), ζ Leo (Adhafera), μ Leo (Rasalas) and ε Leo, it forms an asterism called "Sickle". The red line in the figure is the ecliptic, the yearly path of the Sun across the sky. Picture: Stellarium

In January, the constellation rises in the east in the late evening, in February it is visible there after sunset. But best time to observe Regula - March and April, when in the evenings it is high in the southern part of the sky. At this time, there are few bright stars in the sky, and the huge trapezoid of Leo, together with Regulus shining in it, is one of the most noticeable star patterns in the sky.

By the way, just 20 ′ from Regulus, large telescopes “see” a dim, like a ghost, dwarf galaxy Leo I. This galaxy was discovered in 1950 in photographs taken by the American astronomer Wilson at the Palomar Observatory. Leo I is such a dim object and is located so close to the shining Regulus that it is almost impossible to see it visually even in the largest telescopes. But in the digital age, even amateurs manage to photograph this galaxy.

Leo I is one of the closest galaxies to us, satellite Milky Way. The distance to this star system is 750,000 sv. years - 10,000 times more than before Regulus. Its mass is only about 20 million solar masses. A strange neighborhood: the celestial sapphire Regulus and a dim dwarf galaxy ...

Be sure to look for Regulus in the sky, this relatively close star with an unusual history.

Star parameters

Looking into the spring night sky, even an untrained eye will notice three bright stars that stand out from all the others - these are Arcturus, Spica and Regulus.

Constellation Leo and its alpha - Regulus

The star Regulus or Alpha constellation is one of the brightest stars in the night sky. This star is best seen in spring, when the night sky is not as brightly dotted with stars as it is in summer. In summer, when observing Regulus, some difficulties may arise. Since this star is located close enough to the ecliptic (the path of the Sun in the sky), this celestial body is often obscured by the Moon.

However, in the spring, when Regulus is far from the ecliptic line, it can be easily distinguished among many stars even with the naked eye. And all thanks to the incredible brightness of this star.

Origin of the name and history of discovery

Since Regulus is the 21st star in terms of brightness among the stars visible in the Northern Hemisphere, it is clearly visible against the background of the night sky. Naturally, such a bright star could not remain unnoticed for long. We can find the first mention of the star Regulus in ancient Arabic texts that were written several centuries before the beginning of our era. There, this star is found under the name "Kalb Al-Assad", which translates from Arabic into Russian as "the heart of a lion." But the star Regulus owes the origin of its name Latin. It was the first European astronomers who gave her such a nickname "regulus", by which she is now known throughout the world. From Latin "regulus" (Latin regulus) is translated as "prince" or "king". Indeed, looking at this bright star, one can imagine an Arabian prince walking proudly beside the Lion.

Since this star is the brightest in the constellation Leo, it is also called Alpha Leo. This name corresponds to the astronomical designation - "α Leo", which is considered to be its generally accepted astronomical name.

The unusual shape and speed of rotation of the star

For amateur astronomers, the star Regulus is primarily interesting because, in addition to its extreme brightness, it also has an unusual shape. Since Regulus rotates at a speed of 315 km / s (this is 150 times faster than our Sun rotates!), This star has an oblate appearance - the equatorial radius of this celestial body is almost 1/3 larger than the polar one. Because the star Regulus rotates at such a high speed, it takes less than 16 hours for it to rotate on its axis. Interestingly, if the rotation speed of Regulus were only 14 percent higher, that is, if this star rotated at a speed of 359.1 km / s, its centripetal force of attraction would not be enough to keep the star intact, and it would simply broke up.

Unlike most stars, the axis of rotation of Regulus is tilted, which is why we observe this celestial body as if from an edge. Due high speed rotation of the star, the region of its poles is about half hotter than the equator and five times brighter. The axis of rotation of Regulus coincides with the line of the orbit of this star. For this reason, Regulus moves along the line of his orbit, as it were, on his side, which is a very interesting astronomical phenomenon.

Weight and age

The calculations of modern physicists and astronomers indicate that Regulus is a fairly massive star. Most scientists agree with the opinion that the mass of Regulus is three and a half times the mass of the Sun.

As for the age of the star Regulus, here the opinions of scientists were not always unambiguous. It was previously thought that the age of Regulus is no more than 100 million years, which is an indicator of a young star. Until 2008, scientists attributed Regulus to the category of young stars, while next to this celestial body a dwarf star, Regulus D, was not discovered. This star was in close proximity to Regulus, which allowed scientists to assume that Regulus is much older in age than they previously thought.

Previously, the age of Regulus was determined according to a simple principle. It was believed that since this star rotates so quickly, it means that thermonuclear reactions occur in it much more intensively, and as a result, it cannot live for a long time. On the other hand, since this star has not yet died with such a rapid rotation, it means that it is not yet old. However, the presence of a white dwarf in the Regula system forced scientists to put forward new hypothesis. Its essence lies in the fact that Regulus is an ancient star (it is over 900 million years old!), Which not only intensively burns its own reserves of hydrogen, but also “steals” it from other stars. Due to its own powerful attraction, the star Regulus was able to draw hydrogen from a smaller star - Regulus D, which was next to it. Because of this, the latter turned into a white dwarf much faster than it would have happened in more favorable conditions for it, and Regulus, on the contrary, thus increased the period of its existence.

How to spot Regulus in the night sky

Since Regulus is one of the brightest stars in the night sky, it is not difficult to find it. In addition to the fact that Regulus is located in the constellation Leo, it is also the basis of such a famous asterism as the "Sickle", which is easily distinguishable in the Northern Hemisphere. It is enough to raise your head up and you will see a cluster of stars resembling a sickle or an inverted question mark. The lowest star in this "Sickle" is Regulus.
