HR 2562 b

January 01, 1970

HR 2562 b is a brown dwarf or gas giant exoplanet. It is a substellar companion of the debris disk host star HR 2562.[1] HR 2562 is a sixth-magnitude F-type main-sequence star located 110.92 ± 0.16 light-years (34.007 ± 0.048 pc) away.[2] HR 2562 is about 37% more massive than the Sun.[2]

Initially categorised as brown dwarf, HR 2562 b's exact mass is unknown, and is thought to be 29 ± 15 Jupiter masses,[2] and its luminosity is about solar luminosity.[1][note 1] Its spectral type is L7±3.[1] It was first observed in 2016 using the Gemini Planet Imager.

According to NASA Exoplanet Archive, with a mass of nearly 30 MJ, it is listed as the most massive exoplanet.[3]

HR 2562 b resides interior to the parent star's debris disk, and its orbit is coplanar to it. The disk is inclined 78.0° from the plane of the sky to the line of sight, and ranges from 38 ± 20 au to 187 ± 20 au away from the central star.[2]

Host star edit

The host star of HR 2562 b is HR 2562, a F-type star located 33.63 parsecs (109.7 ly) from the Earth in the constellation Pictor.[4][note 2]It is faintly visible to the naked eye, with an apparent magntiude of 6.11.[4] The mass of HR 2562 is 1.3 M☉, and its age is be between 300 and 900 million years.[4]
