HD 73526 is a star in the southern constellation of Vela. With an apparent visual magnitude of +8.99,[2] it is much too faint to be viewed with the naked eye. The star is located at a distance of approximately 316 light-years (97 parsecs) from the Sun based on parallax,[1] and is drifting further away with a radial velocity of +26 km/s.[4] It is a member of the thin disk population.[4]
The stellar classification of HD 73526 is G6 V,[3] indicating this is a G-type main-sequence star that, like the Sun, is generating energy through core hydrogen fusion. Based on its properties, it may be starting to evolve off the main sequence.[3] This star has slightly more mass than the Sun and a 53% greater radius. The abundance of iron in its atmosphere suggests the star's metallicity – what astronomers term the abundance of elements with higher atomic number than helium – is 70% greater than in the Sun. It is a much older star with an estimated age of nearly ten billion years, and is spinning slowly with a projected rotational velocity of 1.7 km/s. The star is radiating more than double the luminosity of the Sun from its photosphere at an effective temperature of 5,564 K.[4]
