HD 207832 is a

G-type main-sequence star A G-type main-sequence star (Spectral type: G-V), also often, and imprecisely called a yellow dwarf, or G star, is a main-sequence star (luminosity class V) of spectral type G. Such a star has about 0.9 to 1.1 solar masses and an effective temp ...

. Its surface temperature is 5764 K. HD 207832 is slightly enriched compared to the Sun in its concentration of heavy elements, with a

metallicity In astronomy, metallicity is the abundance of elements present in an object that are heavier than hydrogen and helium. Most of the normal physical matter in the Universe is either hydrogen or helium, and astronomers use the word ''"metals"'' as a ...

Fe/H index of 0.17 and is much younger at an age of 0.74 billion years. Kinematically, it belongs to the thin disk of the Milky Way. A multiplicity study in 2014 detected a candidate comoving stellar companion - a red dwarf star or brown dwarf with a spectral class M6.5, at a very wide projected separation of 38.57′ (2.0 light years)

Planetary system

In 2012, two planets, named HD 207832 b and HD 207832 c, were discovered by the

radial velocity method Doppler spectroscopy (also known as the radial-velocity method, or colloquially, the wobble method) is an indirect method for finding extrasolar planets and brown dwarfs from radial-velocity measurements via observation of Doppler shifts in t ...

on wide, eccentric orbits. The planetary system would remain stable even if the planetary orbits are coplanar. Although discovery of the inner planet was confirmed in 2018, the discovery of both planets was suspected to be a false positive in 2020, as newer radial velocity data do not support the existence of the planets.
