HD 80230 is a single[8] star in the southern constellationofCarina, near the northern constellation border with Vela. It has the Bayer designation g Carinae, while HD 80230 is the star's identifier in the Henry Draper catalogue. This is a suspected variable star with a brightness that has been measured varying from magnitude 4.31 down to 4.35,[4] both of which is bright enough for the star to be visible to the naked eye. The distance to this object is approximately 490 light years based on parallax,[1] but it is drifting closer to the Sun with a radial velocity of −5 km/s.[2]
This object is an aging red giant, currently on the asymptotic giant branch,[9] with a stellar classification of M0.5IIIa.[3] It is a mild barium star, showing trace enhancement of s-process elements in its spectrum.[10] The star has 2.2[5] times the mass of the Sun and has expanded to 75[6] times the Sun's radius. It is radiating 1,172 times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 3,904 K.[6]
