HD 8535 is astar located 181light-years (55parsecs) away from theSun in the southernconstellation ofPhoenix. It has a yellow hue and can be viewed using binoculars or a small telescope, having a lowapparent visual magnitude of 7.70.[2] The star is drifting further away from the Sun with aradial velocity of +2.5 km/s.[1]
This is an ordinaryG-type main-sequence star with astellar classification of G0V.[3] Theluminosity class of 'V' indicates the star is generating energy throughcorehydrogen fusion. It is about two[6] billion years old and is spinning slowly with aprojected rotational velocity of 3 km/s.[7] The abundance of elements other than hydrogen and helium in the star – what astronomers termmetallicity – is about the same as in the Sun. It has 17% more mass than the Sun and an 18% greater radius. The star is radiating 1.85 times theluminosity of the Sun from itsphotosphere at aneffective temperature of 6,200 K.[6]
A survey in 2015 has ruled out the existence of any stellar companions at projected distances above 23astronomical units.[9] However, in 2019 awhite dwarf companion to this star was found.[10]
In 2009, agas giant was found in orbit around the star using theradial velocity method. It has anorbital period of 3.59 years and has at least 68% of the mass of Jupiter.[11]
