HD 35520 is a single [6] 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. [2] The distance to this star is approximately 2,200 light years based on parallax. [1] The radial velocity for the star is, as yet, poorly constrained. [2]
This is an aging chemically peculiar star, or Ap 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. [7] It has been classed as a shell star [8] and has a relatively high projected rotational velocity for its class of 80 km/s. [3] The star has expanded to 23 [1] times the radius of the Sun and it is radiating 1,635 [1] times the Sun's luminosity from its enlarged photosphere at an effective temperature of 7,645 K. [1]
