Auriga (Chinese Astronomy)
The modern constellation Auriga (constellation), Auriga lies across two of the quadrants symbolized by the White Tiger (Chinese constellation), White Tiger of the West (西方白虎, ''Xī Fāng Bái Hǔ'') and the Vermilion Bird (Chinese constellation), Vermillion Bird of the South (南方朱雀, ''Nán Fāng Zhū Què''), and Three Enclosures (三垣, ''Sān Yuán''), that divide the sky in traditional Traditional Chinese star names#Categories of Chinese traditional uranography, Chinese uranography. The name of the western constellation in modern Chinese is 御夫座 (''yù fū zuò''), meaning "the driving man constellation".

Auriga (constellation)
Auriga is a constellation in the northern celestial hemisphere. It is one of the 88 modern constellations; it was among the 48 constellations listed by the 2nd-century astronomer Ptolemy. Its name is Latin for '(the) charioteer', associating it with various mythological beings, including Erichthonius and Myrtilus. Auriga is most prominent during winter evenings in the northern Hemisphere, as are five other constellations that have stars in the Winter Hexagon asterism. Because of its northern declination, Auriga is only visible in its entirety as far south as -34°; for observers farther south it lies partially or fully below the horizon. A large constellation, with an area of 657 square degrees, it is half the size of the largest, Hydra. Its brightest star, Capella, is an unusual multiple star system among the brightest stars in the night sky. Beta Aurigae is an interesting variable star in the constellation; Epsilon Aurigae, a nearby eclipsing binary with an unusually l ...

5 Aurigae
5 Aurigae is a triple star system in the northern constellation of Auriga, located about 195 light years away from the Sun based on parallax. It is just visible to the naked eye as a dim, yellow-white hued star with an apparent visual magnitude of 5.95. The system is moving away from the Earth with a heliocentric radial velocity of +6 km/s, having come within some 8.7 million years ago. This was initially discovered to be a binary star system by Otto Struve. The outer pair has an orbital period of 1,598 years with an eccentricity of 0.536. The magnitude 6.02 primary, component A, is itself a binary system consisting of two stars of similar mass, roughly 1.5 times the mass of the Sun each, with an orbital period of . It has a stellar classification of F5 V, matching an F-type main-sequence star. As of 2017, component B is a magnitude 9.50 star at an angular separation of from the primary along a position angle of 285°. References Externa ...

12 Aurigae
12 Aurigae is a Be star in the northern constellation Auriga. It lies below the normal limit for visibility to the naked eye, having an apparent visual magnitude of 6.988. It lacks a designation from the Hipparcos catalogue. It is located just under half a degree north of Capella. Assigned spectral classes for 12 Aurigae vary greatly from B2 to B5 and the luminosity class from V ( main sequence) to Ia (luminous supergiant). Its spectrum shows prominent emission lines, but the spectrum is complicated by the appearance of sharp shell components to some of the spectral lines. The colour of the star as shown by the B-V and U-B colour indices is not consistent with an early B spectral class, leading to many estimates of its effective temperature that are much lower than expected for a B-class star. The expected temperature for a B5 spectral type would be , but most sources assign a temperature of around . Other properties also vary between different sources, for example ...

40 Aurigae
40 Aurigae is a binary star in the constellation Auriga. Its apparent magnitude is 5.345, meaning it can just barely be seen with the naked eye. Based on parallax estimates made by the Hipparcos spacecraft, the system is located some 340 light-years (104 parsecs) away. 40 Aurigae is a spectroscopic binary, meaning the two stars are too close to be individually resolved, but periodic Doppler shifts in their spectra indicate there must be orbital motion. In this case, light from both stars can be detected and it is a double-lined spectroscopic binary. The two have an orbital period of 28.28 days and a fairly high eccentricity of 0.56. The primary star is an A-type main-sequence star and shows unusual absorption lines in its spectrum, so it is an Am star with an effective temperature The effective temperature of a body such as a star or planet is the temperature of a black body that would emit the same total amount of electromagnetic radiation.
