This is a list of brown dwarfs. These are objects that have masses between heavy gas giants and low-mass stars. [1] The first isolated brown dwarf discovered was Teide 1 in 1995. [2] The first brown dwarf discovered orbiting a star was Gliese 229 B, also discovered in 1995. [3] The first brown dwarf found to have a planet was 2M1207, discovered in 2004. [4] As of 2015 [update] , more than 2,800 brown dwarfs have been identified. [5] 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. Brown dwarfs with names ending in a letter such as B, C, or D are in orbit around a primary star; those with names ending in a lower-case letter such as b, c, or d, may be exoplanets (see Exoplanet naming convention).
Some exoplanets, especially those detected by radial velocity, 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).
A complete list of more than 3000 ultracool dwarfs, which includes brown dwarfs and low-mass stars, is being maintained by astronomers. It is called the UltracoolSheet. [6] The same team also produced a list of 1000 ultracool dwarfs with their mass being determined. [7]
Sorted by increasing right ascension of the parent star. Brown dwarfs within a system sorted by increasing orbital period.
Some brown dwarfs listed could still be massive planets.

A stellar remnant can be for example a white dwarf, a pulsar or a black hole. Objects with a mass of a brown dwarf, but with a history of mass-transfer might not be brown dwarfs. If they exist as a period bouncer around a white dwarf they are thought to once have been stars and are today "brown dwarf-like objects". [19] Objects around black widow pulsars on the other hand are thought to be white dwarfs that lost mass to the pulsar and therefore will differ in composition and density compared to brown dwarfs. [20] This list is sorted after the discovery year.

Brown dwarfs are substellar objects that have more mass than the biggest gas giant planets, but less than the least massive main-sequence stars. Their mass is approximately 3 to 80 times that of Jupiter (MJ)—not big enough to sustain nuclear fusion of ordinary hydrogen (1H) into helium in their cores, but massive enough to emit some light and heat from the fusion of deuterium (2H). The most massive ones can fuse lithium (7Li).
WD 0137-349 is a binary star in the constellation of Sculptor. It is located about 330 light-years away, and appears exceedingly faint with an apparent magnitude of 15.33.
An object with the spectral type T is either a brown dwarf or young free-floating planetary-mass object. An directly imaged exoplanet with a young age can also be a T-dwarf. T dwarfs are colder than L dwarfs, but warmer than Y dwarfs.
LP 944-20 is a dim brown dwarf of spectral class M9 located 21 light-years from the Solar System in the constellation of Fornax. With a visual apparent magnitude of 18.69, it has one of the dimmest visual magnitudes listed on the RECONS page. It is one of the brightest brown dwarfs, if not the brightest at JMKO=10.68±0.03 mag.
TVLM 513-46546 is an M9 ultracool dwarf at the red dwarf/brown dwarf mass boundary in the constellation Boötes. It exhibits flare star activity, which is most pronounced at radio wavelengths. The star has a mass approximately 80 times the mass of Jupiter. The radio emission is broadband and highly circularly polarized, similar to planetary auroral radio emissions. The radio emission is periodic, with bursts emitted every 7054 s, with nearly one hundredth of a second precision. Subtle variations in the radio pulses could suggest that the ultracool dwarf rotates faster at the equator than the poles in a manner similar to the Sun.
An object with the spectral type L can be either a low-mass star, a brown dwarf or a young free-floating planetary-mass object. If a young exoplanet or planetary-mass companion is detected via direct imaging, it can also have an L spectral type, such as Kappa Andromedae b.
Gliese 318 is a white dwarf in the constellation Pyxis. Its spectral type is DA5.5 and it has a visual magnitude of 11.85, and lies 27.8 light-years away. The star was too faint to have had its parallax measured by the Hipparcos satellite. Earth-based measurement in 2009 gave its parallax as 113.63 ± 1.97 milliarcseconds, yielding a distance of 28.7 ± 0.5 light-years; this parallax measurement has since been substantially improved by Gaia. It is around 45% as massive as the Sun but has only 0.15% its luminosity.
A Peter Pan disk is a circumstellar disk around a star or brown dwarf that appears to have retained enough gas to form a gas giant planet for much longer than the typically assumed gas dispersal timescale of approximately 5 million years. Several examples of such disks have been observed to orbit stars with spectral types of M or later. The presence of gas around these disks has generally been inferred from the total amount of radiation emitted from the disk at infrared wavelengths, and/or spectroscopic signatures of hydrogen accreting onto the star. To fit one specific definition of a Peter Pan disk, the source needs to have an infrared "color" of , an age of >20 Myr and spectroscopic evidence of accretion.
A post-common envelope binary (PCEB) or pre-cataclysmic variable is a binary system consisting of a white dwarf or hot subdwarf and a main-sequence star or a brown dwarf. The star or brown dwarf shared a common envelope with the white dwarf progenitor in the red giant phase. In this scenario the star or brown dwarf loses angular momentum as it orbits within the envelope, eventually leaving a main-sequence star and white dwarf in a short-period orbit. A PCEB will continue to lose angular momentum via magnetic braking and gravitational waves and will eventually begin mass-transfer, resulting in a cataclysmic variable. While there are thousands of PCEBs known, there are only a few eclipsing PCEBs, also called ePCEBs. Even more rare are PCEBs with a brown dwarf as the secondary. A brown dwarf with a mass lower than 20 MJ might evaporate during the common envelope phase and therefore the secondary is supposed to have a mass higher than 20 MJ.
SDSS J1228+1040 is a white dwarf with a debris disk around it. The disk formed when a planetary body was tidally disrupted around the white dwarf. It is the first gaseous disk discovered around a white dwarf.
SDSS 1557 is a binary system composed of a white dwarf and a brown dwarf. The system is surrounded by a circumbinary debris disk. The debris disk was formed when a minor planet was tidally disrupted around the white dwarf in the past.
WD 1425+540 (G200-39) is a white dwarf that accreted an exocomet. This is evident from the pollution of the white dwarf atmosphere with metals, especially the pollution with nitrogen. WD 1425+540 is the first white dwarf with detected nitrogen. The white dwarf has a K-dwarf companion called G200-40, about 40 arcseconds away. The white dwarf nature of the object was discovered by Greenstein in 1974.
GALEX J2339–0424 is a white dwarf that is suspected to be polluted with material originating from an icy exomoon. This is evident from the first detection of beryllium in this white dwarf, together with GD 378.
2MASS J0920+3517 is a triple brown dwarf system. Alternatively it is a low-mass star orbiting a pair of brown dwarfs.
