WebAug 1, 2024 · Brown dwarfs have been found in stellar nurseries alongside young protostars. They have been found in binary systems paired with white dwarfs, having survived potential engulfment by the... Since then, over 1,800 brown dwarfs have been identified, even some very close to Earth like Epsilon Indi Ba and Bb, a pair of brown dwarfs gravitationally bound to a Sun-like star 12 light-years from the Sun, and Luhman 16, a binary system of brown dwarfs at 6.5 light-years from the Sun. See more Brown dwarfs (also called failed stars) are substellar objects that are not massive enough to sustain nuclear fusion of ordinary hydrogen ( H) into helium in their cores, unlike a main-sequence star. Instead, they have a mass … See more The standard mechanism for star birth is through the gravitational collapse of a cold interstellar cloud of gas and dust. As the cloud contracts it heats due to the Kelvin–Helmholtz mechanism. Early in the process the contracting gas quickly radiates away … See more The super-Jupiter planetary-mass objects 2M1207b, 2MASS J044144 and Oph 98 B that are orbiting brown dwarfs at large orbital distances may have formed by cloud collapse rather than accretion and so may be sub-brown dwarfs rather than planets, which is inferred … See more Early theorizing The objects now called "brown dwarfs" were theorized by Shiv S. Kumar in the 1960s to exist and were originally called black dwarfs, a classification for dark substellar objects floating freely in space that were not … See more Classification of brown dwarfs Spectral class M These are brown dwarfs with a spectral class of M5.5 or … See more Brown dwarfs form similarly to stars and are surrounded by protoplanetary disks, such as Cha 110913−773444.
