A brown dwarf is being observed by an M dwarf, known as TOI-2119. The object is 70 times larger than Jupiter and is on a star. The paper was published on arXiv.org.
The mass range for brown dwarfs is between 13 and 80 Jupiter mass. Many brown dwarfs have been found, but they are rare.
Massive brown dwarfs are extremely rare and difficult to find because they are so close to their hosts. The brown dwarf desert is constantly studied by astronomy, trying to find other examples of this type.
A new massive brown dwarf has been found by an astronomer led by Penn State's Caas. The brown dwarf object was confirmed using a combination of ground-based and space-based photometry and high-precision velocimetry from the Habitable.
During Sectors 24 and 25 TESS observed TOI-2119 in short-cadence mode. The TESS Science Processing Operations Center has identified one transiting candidate, TOI-2119.01.
The TOI-2119.01 has a mass of 67 Jupiter mass and a radius of 1.11 Jupiter radii according to the study. The results yielded a density of 60 g/ cm3.
The brown dwarf circles TOI-2119 every 7.2 days on an eccentric path that is 88.51 degrees away from it. The object's brightness was found to be over 2200 K.
The host star TOI-2119 is an M dwarf, which is half the size and mass of the sun. It has a rotation period of 13 days and an effective temperature of 3,553 K.
The researchers said that the high eccentricity of TOI-2119.01 may be the result of interactions with a long-period companion. The high mass of this brown dwarf points to a formation scenario because of the instability in the disk.
The authors of the paper said that the simulations show that brown dwarf systems can be formed in a variety of configurations.
