Astronomers are digging under the brown dwarfs

Astronomers have focused all their attention on brown dwarfs, trying to uncover all of their secrets. Despite the fact that brown dwarfs are not the full-fledged stars, and substars and occupy an intermediate niche between these massive stars and planets, they cause enormous interest among scientists. Astronomers from around the world are trying to figure out what is more like brown dwarfs: the planets or stars. What a performance they made more or are they still are an entirely different stage of development than the traditional brown dwarfs and planets. In addition, the astronomers looking for protoplanetary disks around brown dwarfs, and the worlds that are formed in these disks.

P astronomers, mass brown dwarfs can vary from 13 to 80 wt be our planets and too small to be stars. The study of more brown dwarfs using the telescope Optical Gravitational Lensing Experiment (OGLE) helped scientists discover a sufficient potential for the formation of planets orbiting brown dwarfs. Planets are formed in protoplanetary disks around lackluster substars or, as they are called, chemical stars. Chemicals called brown dwarfs are stars because they go thermonuclear fusion reactions in the nuclei of light elements (deuterium, lithium, beryllium, boron), but, in contrast to the main-sequence stars, the contribution of such stars in the heat of nuclear fusion reaction of hydrogen nuclei (protons ) is negligible, and, after the exhaustion of stocks of the nuclei of light elements, fusion reactions in their interiors are terminated, after which they are relatively cool rapidly, becoming a planet like object.
