Brown Dwarf -- Brown dwarfs are a special type of low-mass star (approximately 13-70 Jupiter masses) that do not have nuclear fusion occurring in their cores during their time on the main sequence.

Many brown dwarfs continue to glow in the red and infrared after their lithium is exhausted. This glow is...
