HD 63513 (HR 3036) is a solitary star located in the southerncircumpolar constellationVolans. It has anapparent magnitude of 6.38, placing it near the maxnaked eye visibility. The star is situated at a distance of 634light years[1] but is receding with a heliocentricradial velocity of1.4 km/s.[5]

This object is a star with the characteristics of a G6 and G8giant.[3] At present it has 3.14 times themass of the Sun but has expanded to almost 13 times theSun's girth.[7] It shines at 102solar luminosities from its enlargedphotosphere at aneffective temperature of 5,116K,[7] which gives it a yellow glow. HD 63513 has an iron abundance 102% that of theSun,[7] placing it at solarmetallicity and spins modestly with aprojected rotational velocity of1.9 km/s.[8]
