WHAT DOES BROWN DWARF MEAN IN ENGLISH?

brown dwarf

Brown dwarf

Brown dwarfs are substellar objects too low in mass to sustain hydrogen-1 fusion reactions in their cores, unlike main-sequence stars. They occupy the mass range between the heaviest gas giants and the lightest stars, with an upper limit around 75 to 80 Jupiter masses. Brown dwarfs heavier than about 13 MJ are thought to fuse deuterium and those above ~65 MJ, fuse lithium as well. The difference between a very-low-mass brown dwarf and a giant planet has been recently debated. A similar discussion involves DENIS-P J082303.1-491201 b, the lower-mass member of an ultracool binary system with a mass of nearly 29 Jupiter masses and listed as the most massive exoplanet yet found as of March 2014. Nonetheless, one school of thought is based on formation; another, on physics in the interior. Dwarfs are categorized by spectral classification, with the major types being M, L, T, and Y. Despite their name, brown dwarfs are different colours. Many brown dwarfs would likely appear magenta to the human eye according to A. J. Burgasser, whereas another source has noted orange/red.
