unusual facts about Brown dwarf


Brown dwarf

In 1988, however, University of California, Los Angeles professors Eric Becklin and Ben Zuckerman identified a faint companion to a star known as GD 165 in an infrared search of white dwarfs.


Baryonic dark matter

Candidates for baryonic dark matter include non-luminous gas, Massive Astrophysical Compact Halo Objects (MACHOs: condensed objects such as black holes, neutron stars, white dwarfs, very faint stars, or non-luminous objects like planets), and brown dwarfs.

Kappa1 Ceti

Using the radial velocity technique, the search for substellar companions has thus far failed to find a brown dwarf or extrasolar planet in the "hot zone" orbit around Kappa1 Ceti.

Starwisp

Charles Stross, in his novel Accelerando, propels a small payload to a hypothetical brown dwarf star, 3 light-years away, using a Starwisp propulsion system, as well as using starwisps as kinetic-kill missiles against space-based warships.

Sulfanyl

Sulfanyl is one of the top three sulfur containing gasses in gas giants such as Jupiter and is very likely to be found in brown dwarfs and cool stars.

Super-Jupiter

For example, companions at the planet–brown dwarf borderline have been called super-Jupiters, such as around the star Kappa Andromedae.

HD 131664

This brown dwarf has mass of at least 18.15 times that of Jupiter and orbits in a long-period, eccentric orbit.

Kappa Andromedae b

It is unclear whether Kappa Andromedae b is a gas giant or a brown dwarf—that is, an object massive enough to fuse deuterium but not hydrogen-1.
