Within the NS WD merger, the main burst of GRB … WebWhen brown dwarfs are very young, they generate some energy from the fusion of heavy hydrogen, or deuterium, into helium nuclei, but this supply is used up in a few tens of millions of years. After that brown dwarfs glow because of the heat generated by the release of gravitational energy as they slowly contract.
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.
