Scientists confirm Gliese 229B is a pair of brown dwarfs, not one Gliese 229Ba and Gliese 229Bb complete their orbits in 12 days. New findings suggest there could be more hidden brown dwarf pairs ...

The brown dwarf, named Gliese 229B, was discovered in 1995 but has puzzled astronomers ever since, as it appears to be too dim for its heavy mass. Now, according to two new papers in the journals ...

So the brown dwarf that three decades ago was named Gliese 229B is now recognized as Gliese 229Ba, with a mass 38 times greater than our solar system's largest planet Jupiter, and Gliese 229Bb ...

In 1995, Caltech researchers at the Institute's Palomar Observatory first observed what appeared to be a brown dwarf orbiting Gliese 229 – a red dwarf star located about 19 light-years from Earth.

Gliese 229B was the first known brown dwarf, discovered in 1995. In new research, astronomers observed Gliese 229 B with the GRAVITY interferometer and, separately, the CRIRES+ spectrograph at ESO’s ...
