List of brown dwarfs

From Wikipedia, the free encyclopedia
Jump to: navigation, search

The first isolated brown dwarf discovered was Teide 1 in 1995. The first brown dwarf discovered orbiting a star was Gliese 229 B, also discovered in 1995. The first brown dwarf found to have a planet was 2M1207, discovered in 2004. As of 2012, more than 1800 brown dwarfs have been identified.[1] An isolated object with less than about 13 Jupiter masses is technically a sub-brown dwarf or rogue planet.

Because the mass of a brown dwarf is between that of a planet and that of a star, they have also been called planetars or hyperjovians. Various catalog designations have been used to name brown dwarfs; names ending in 'b' are in orbit around a primary star.

Some extrasolar planets can turn out to be brown dwarfs if their mass is higher than originally thought: most have only known minimum masses because the inclination of their orbit is not known. Examples include HD 114762 b (>11.68 MJ), Pi Mensae b (>10.312 MJ), and NGC 2423-3 b (>10.6 MJ).
