Retrieved from https://theplanets.org/stars/regulus-star/. The cloud was discovered by radio astronomers in 1983. It contains a nuclear star-forming ring, almost 2000 light-years across, where a large proportion of the galaxys star formation takes place. Leo 1 is difficult to see due to its proximity to Regulus. The central region of M95 has a ring-shaped starburst region around the core with a diameter spanning about 2,000 light years. History and mythology of Aldebaran. They have a combined apparent magnitude of 3.53. In medieval astrology, Regulus was one of the 15 Behenian fixed stars, believed to hold special astrological power. Other ancient cultures also saw it as a herald of kingly power. The star is also known by its Latin name Cor Leonis and the Arabic Qalb al-Asad (Kalb al Asad, Kabeleced).

The WGSN's first bulletin of July 2016[22] included a table of the first two batches of names approved by the WGSN; which included Regulus for this star. It has 214% of the solar radius and is about 15 times more luminous than the Sun. The stars traditional name, Alterf, comes from the Arabic a-arf, which means the view (of the lion).. The main star Regulus A is large and blue with a spectral type of B8 IVn. Because Regulus can stray within the ecliptic, or the path upon which the sun and planets travel, it is very occasionally eclipsed by one of the planets or an asteroid. It is the object within the Regulus system that can be seen with the naked eye. The Persians knew the constellation as Shir or Ser, Babylonians called it UR.GU.LA (the great lion), Syrians knew it as Aryo, and the Turks as Artan.

Regulus lies only 0.46 degrees from the ecliptic, which is the Suns apparent path across the sky, through the zodiac constellations, and is regularly occulted by the Moon and very rarely by Mercury and Venus. The stars projected rotational velocity is 128 km/s. The name Regulus means the little king or prince in Latin. Wolf 359 is classified as a flare star, one that can undergo dramatic increases in luminosity for several minutes as a result of magnetic activity on its surface. Like Regulus, Denebola is a rapid rotator, which results in an oblate shape of the star, with a bulge at the equator. Fierce lion-headed deities, like Sekhmet whose breath formed the desert, and Tefnut who fled to the desert of Nubia in her rage, and the war-god Maahes, were associated both with scorching heat and protection of the pharaoh. The Leonids usually peak on November 17-18 every year and have a radiant near the bright star Gamma Leonis. History and Mythology. The other components of the Alpha Leonis system are still on the main sequence, but considerably fainter than Regulus A. The staff is so caring and amazing. The main component in the Regulus A system is orbited by a companion with at least 0.3 solar masses. A Type Ia supernova, SN 1998bu, was discovered in M96 in May 1998. Among the odd effects on the star: Regulus is much hotter at its poles (27,212 F, or 15,100 C) than its equator (18,032 F or 10,000 C). Mira variables are pulsating variable stars that are in the late stage of evolution, very red in colour, and with pulsation periods longer than 100 days. Leo is the 12th largest constellation in size, occupying an area of 947 square degrees. Regulus B and Regulus C take about 600 years to complete an orbit around a common centre of mass. Regulus is not a binary star for once, although there is a binary nearby, and possibly a white dwarf. Leo and Regulus, picture from Nasa. 2 stars. If the star were spinning 10 percent faster, it would fly apart as its gravity would not be strong enough to hold it together. [citation needed] In Chinese it is known as , the Fourteenth Star of Xuanyuan, the Yellow Emperor. The royal stars are mentioned in the Bundahishn, a collection of Zoroastrian cosmogony and cosmology. The companion star has an apparent magnitude of 4.8. With a surface temperature of 11,668 K, it shines with 316.2 solar luminosities. Its traditional name (Regulus) means "the little king". Regulus is the luminary of the constellation Leo. It has a visual magnitude of 10.67 and is 33.1 light years distant. He's a former planetarium director in Little Rock, Fort Worth and Denver and an adjunct faculty member at Metropolitan State University of Denver. With just 1/3 the mass of the sun, Regulus C is a red dwarf star with a spectral classification of M4V. Regulus B and C are gravitationally bound to each other, and together theyre called Regulus BC. Regulus - Alpha Leonis - Constellation Guide Leo's brightest star, Regulus, was often called the "Red Flame" and was thought to contribute to the heat of summer. It's the brightest star in the constellation and among the brightest in Earth's night sky. Oops! Regulus A is the dominant star, with a binary companion 177" distant that is thought to be physically related. 2.113), Zosma (Delta Leo, mag. The star is an exceptionally fast rotator, with a rotation period of only 15.9 hours. Regulus is part of the Sickle of Leo, a sickle-shaped asterism that represents the head of the celestial Lion. The name of this star is a diminutive form of the Latin Rex. NGC 3628 is an unbarred spiral galaxy approximately 35 million light years distant from the solar system. While watching the sky, the dominant star would appear in its season, each having a time of the year when most noticeable. Your email address will only be used for EarthSky content. EarthSky | Aldebaran is Taurus the Bull's bloodshot eye These limelight-hogging celestial objects combine whirling, pinwheeling arms with scatterings of sparkling stars, glowing bursts of gas, and dark, weaving lanes of cosmic dust, creating truly awesome scenes especially when viewed through a telescope such as the NASA/ESA Hubble Space Telescope. Regulus A is a binary star consisting of a blue-white subgiant star of spectral type B8, which is orbited by a star of at least 0.3 solar masses, which is probably a white dwarf. The star was listed as one of four "royal stars," first under the name Venant and then Miyan ("the center", according to the Encyclopedia of Astronomy and Astrophysics.). Southwest Valley Chamber of Commerce . It is located at 79 light-years from us.
