HD 207832
HD 207832 is a sun-like star in the constellation Piscis Austrinus. It is a G5V main-sequence star with a surface temperature of about 5764 K, a mass of roughly 1.08 times the Sun, a radius of 0.97 solar radii, and a luminosity about 0.78 times that of the Sun. Its metallicity is slightly higher than the Sun’s (+0.17 dex), and it is relatively young at about 0.74 billion years old. The star sits about 193 light-years away and shines at an apparent magnitude of 8.79, so it isn’t visible to the naked eye.
HD 207832 moves through the Milky Way’s thin disk and has a measured radial velocity of about -16.5 km/s. It also has measurable proper motion and parallax that place it at the distance above.
In 2014, a distant companion star or brown dwarf of spectral class around M6.5 was detected, appearing at a very wide projected separation of about 2 light-years.
Two planets, named HD 207832 b and c, were announced in 2012 based on radial velocity measurements, orbiting the star on wide, eccentric paths. The system was thought to be stable even if the planets shared the same orbital plane. The inner planet’s existence was confirmed in 2018. However, by 2020 newer data suggested that both planets might be false positives, and their existence is not currently confirmed.
