36 Aurigae is a single[9] variable star located about 910[2] light years away from the Sun in the constellation Auriga. It has the variable star designation V444 Aurigae, while 36 Aurigae is the Flamsteed designation.[8] This object is visible to the naked eye as a dim, white-hued star with a baseline apparent visual magnitude of 5.71. It is moving further from the Earth with a heliocentric radial velocity of +16 km/s.[3]
This is a magnetic chemically peculiar star that has been given stellar classifications of A1 Vp Si[4] and B9.5p Si,Fe,[1] indicating it is a late B- or early A-type star showing peculiarities of silicon and iron in the spectrum. It is an Alpha2 Canum Venaticorum variable that ranges in visual magnitude from 5.70 down to 5.74 with a period of 14.368 days.[5] The star has 4.4[6] times the mass of the Sun and is radiating 724 times the Sun's luminosity from its photosphere at an effective temperature of 10,046 K.[6]
