Brown dwarfs are the cosmic equivalent of tweeners. They're too massive to be planets and too small to sustain nuclear fusion in their cores, which powers stars. Many brown dwarfs are nomadic. They do not orbit stars but ...

Using the Low-Frequency Array (LOFAR) radio telescope, an international team of astronomers has discovered a new radio source that turns out to be a cold brown dwarf. The object, designated BDR 1750+3809, is so far the first ...
Astronomers have used the National Science Foundation's Karl G. Jansky Very Large Array (VLA) and NASA's Spitzer Space Telescope to make the first measurement of wind speed on a brown dwarf—an object intermediate in mass ...

By combining high-precision astrometry and adaptive optics-resolved imaging, astronomers have found that the binary system WISE J0720−0846, better known as Scholz's star, hosts a T dwarf, confirming previous assumptions. ...
An international team of astronomers has detected a new brown dwarf with an ultra-short orbital period that transits an active M-dwarf star. The newfound object, designated NGTS-7Ab, turns out to be the shortest period transiting ...
An international team of astronomers has found a new brown dwarf, one of the most massive objects of this type discovered to date. The newly detected brown dwarf, designated EPIC 212036875 b, turns out to be about 50 times ...
Aiming to constrain the orbit and dynamical mass of the brown dwarf in the HD 206893 system, an international team of astronomers has investigated the host star and its companion using a combination of observing techniques. ...
