HD 37519 is a star in the northern constellation Auriga. It has a blue-white hue and is dimly visible to the naked eye with an apparent visual magnitude of 6.04.^[3] The distance to HD 37519 is approximately 790 light years based on parallax, but it is drifting closer with a radial velocity of −10 km/s.^[2][6]

Anne Cowley in 1972 found a stellar classification of B9.5III-IV(p)? (Hg?) for this star,^[4] suggesting it is an evolved B-type star and a suspected chemically peculiar star of the mercury-manganese type.^[12] It is estimated to be 375 million years old and with a high rate of spin, showing a projected rotational velocity of 195 km/s.^[10] In March 1964, a suspected flare of HD 37519 was detected that increased the star's brightness by about three magnitudes. Smaller variations of up to two magnitudes were detected a few days later,^[13] suggesting there might be a flare star companion. However, follow-up observations failed to confirm the variability.^[14] The star is radiating 221 times the luminosity of the Sun^[9] from its photosphere at an effective temperature of 10,677 K.^[8]
