WebJul 26, 2024 · But no, the reason that there is a lower mass limit for fusion is that these low mass brown dwarfs and giant planets have electron-degenerate interiors. This means the central pressure becomes independent of temperature and that an object below the D-burning threshold can effectively cool at constant density. i.e. WebAug 2, 2013 · Some people think of brown dwarfs as failed stars. Although brown dwarfs never truly become stars, some of them are able to act the part, for a short while. To start fusion, the very lowest-mass stars need about 80 times the mass of Jupiter. However, if a brown dwarf has at least 13 times the mass of Jupiter, it can ignite a limited form of fusion.
