What are Brown Dwarfs?
Brown Dwarf is a type of substellar object in the universe, whose mass is between the largest planets with the heaviest gas and the lightest stars, and which has a mass between 13 and 75-80 times that of Jupiter. , Or approximately 2.5 × 1028 kg. Or about 1.5 × 1029 kg.
These sub-brown dwarfs are considered below the limits of all these masses, which some scientists sometimes refer to as rogue planets. The brown dwarf, ie Brown Dwarf, can be completely convection (transfer of heat due to the simultaneous movement of very large molecules within the fluid), with no layer or chemical differentiation, ie, deepening.
Unlike the stars in the main sequence, brown dwarfs are not sufficiently large to maintain the simple fusion of simple hydrogen to helium in their core. While they are believed to fuse deuterium and fuse to lithium, it is also a matter of debate as to whether brown dwarfs would be better defined by their formation processes rather than their perceived nuclear fusion reactions.
Stars are classified by spectral class, with brown dwarfs designated as M, L, T, and Y. Despite their names, brown dwarfs are of different colors. Many brown dwarfs will likely appear magenta, or possibly orange/red to the human eye. Brown dwarfs are not very bright at visible wavelengths. Planets known for brown dwarfs are: 2M1207b, MOA-2007-BLG-192Lb, and 2MASS J044144b.
At a distance of about 6.5 light-years, the closest known brown dwarf is Luhman 16, a binary system of brown dwarfs discovered in 2013. The HR2562B is listed as the largest known exoplanet in NASA’s exoplanet (as of December 2017). The collection, despite having a mass (30 M 15 MJ) more than double the 13-Jupiter-mass cutoff between planets and brown dwarfs.
