Short description: Star in the constellation Andromeda
13 Andromedae, abbreviated 13 And, is a single,[10] blue-white hued variable star[5] in the northern constellation of Andromeda. 13 Andromedae is the Flamsteed designation, while it bears the variable star designation V388 Andromedae. With a typical apparent visual magnitude of around 5.75,[3] it is dimly visible to the naked eye under good seeing conditions. The distance to this star can be directly estimated from its annual parallax shift of 10.9 mas,[2] yielding a range of 300 light years. At that distance, its brightness is diminished by an extinction of 0.13 magnitude due to interstellar dust.[7] The star is moving closer to the Earth with a heliocentric radial velocity of −8 km/s.[6]
This is a magnetic chemically peculiar star that has been assigned stellar classifications of B9 III or B9 Mn.[4] It is a variable star of the Alpha2 Canum Venaticorum type, ranging in magnitude from 5.73 down to 5.77[5] with a period of 1.47946 days.[4] The star has a high rate of spin, showing a projected rotational velocity of 75 km/s.[8] 13 Andromedae is around 345[7] million years old and shines with 43[3] times the Sun's luminosity.
