HD 35520 is a single[8] star in the northern constellation of Auriga. It has a white hue and is dimly visible to the naked eye with an apparent visual magnitude of 5.92.[1] The distance to this star is approximately 2,200 light years based on parallax.[2] The radial velocity for the star is, as yet, poorly constrained.[1]
This is an Ap star, a type of chemically peculiar star, in the giant stage of its evolution, with a stellar classifications of A1 III[3] and A1p.[4] The spectrum displays abundance anomalies of helium and silicon.[9] It has been classed as a shell star[10] and has a relatively high projected rotational velocity for its class of 80 km/s.[3] The star has expanded to 23 times the radius of the Sun and it is radiating 2,686 times the Sun's luminosity from its enlarged photosphere at an effective temperature of Script error: No such module "val"..[6]
