SIMBAD	data

HD 70514 (HR 3280) is a solitary star located in the southern circumpolar constellation Volans. With an apparent magnitude of 5.06, its faintly visible to the naked eye. The star is located 296 light years away from the Solar System, and is drifting away with a radial velocity of 1.98 km/s.

Properties

HD 70514 is classified as a "K1 III" star, which means that this is a giant star that has exhausted hydrogen at its core and left the main sequence. It has 1.9 times the mass of the Sun but has expanded to 15 times the sun's diameter. It radiates at 99 solar luminosities from its enlarged photosphere at an effective temperature of 4,515 K, which gives it an orangish-yellow hue. HD 70514 has a metallicity 126% that of the Sun, and it rotates rather slowly.
