Preferred term
dwarf star
Definition(s)
- A dwarf star is a term used, oddly enough, to describe any star that is of normal size for its mass. Such stars lie on the main sequence and are thus in the process of converting hydrogen to helium by nuclear fusion in their cores. The Sun, for example, is classified as a yellow dwarf. Red dwarfs are the smallest and least luminous of main sequence stars. Highly evolved dwarf stars that have left the main sequence include white dwarfs, which are collapsed stars that are still hot and shining by virtue of stored thermal energy, and black dwarfs, which have become so cold that they no longer give off any visible radiation. Brown dwarfs are substellar objects with insufficient mass to be able to fuse hydrogen in their cores.
