SIMBAD data

HD 63513 (HR 3036) is a solitary star located in the southern circumpolar constellation Volans. It has an apparent magnitude of 6.38, placing it near the max naked eye visibility. The star is situated at a distance of 634 light years [1] but is receding with a heliocentric radial velocity of 1.4  km/s. [5]

This object is a star with the characteristics of a G6 and G8 giant. [3] At present it has 3.14 times the mass of the Sun but has expanded to almost 13 times the Sun's girth. [7] It shines at 102 solar luminosities from its enlarged photosphere at an effective temperature of 5,116 K, [7] which gives it a yellow glow. HD 63513 has an iron abundance 102% that of the Sun, [7] placing it at solar metallicity and spins modestly with a projected rotational velocity of 1.9  km/s. [8]
