Xi Aurigae
Star in the constellation Auriga
Xi Aurigae, Latinized from ξ Aurigae, is the Bayer designation for a single,[9] white-hued star in the northern constellation of Auriga. This star was once considered part of the constellation of Camelopardalis and held the Flamsteed designation 32 Camelopardalis.[10] It is visible to the naked eye with an apparent visual magnitude of +5.0.[2] The measured annual parallax shift of this star is 13.37 ± 0.17 mas,[1] which corresponds to a physical distance of 244 light-years (75 parsecs) with a 3 light-year margin of error. At that distance, the visual magnitude of the star is diminished by an extinction of 0.108 due to interstellar dust.[11]
This is an A-type main sequence star with a stellar classification of A2 Va.[3] Although it was one of the first stars to be cataloged as a Lambda Boötis star, Murphy et al. (2015) don't consider it to be a member of this population.[3] The star has nearly twice[6] the mass of the Sun and about 1.1[7] times the Sun's radius. It is an estimated 174[6] million years old and is spinning with a projected rotational velocity of 62 km/s.[6] Xi Aurigae is radiating 49.5[5] times the Sun's luminosity from its photosphere at an effective temperature of around 9,152 K.[6]
