HD 8535 is a star located 181 light-years (55 parsecs) away from the Sun in the southern constellation of Phoenix. It has a yellow hue and can be viewed using binoculars or a small telescope, having a low apparent visual magnitude of 7.70. [2] The star is drifting further away from the Sun with a radial velocity of +2.5 km/s. [1]
This is an ordinary G-type main-sequence star with a stellar classification of G0V. [3] The luminosity class of 'V' indicates the star is generating energy through core hydrogen fusion. It is about two [6] billion years old and is spinning slowly with a projected rotational velocity of 3 km/s. [7] The abundance of elements other than hydrogen and helium in the star – what astronomers term metallicity – 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 the luminosity of the Sun from its photosphere at an effective temperature of 6,200 K. [6]
A survey in 2015 has ruled out the existence of any stellar companions at projected distances above 23 astronomical units. [9] However, in 2019 a white dwarf companion to this star was found. [10]
In 2009, a gas giant was found in orbit around the star using the radial velocity method. It has an orbital period of 3.59 years and has at least 68% of the mass of Jupiter. [11]
