If i remember correctly, a brown dwarf is a failed star. Nuclear reactions started briefly at it's core, but there isn't enough mass to sustain it. So it's a stellar corpse, just sitting out there.

All stars start as protostars. Depending on their mass, they will eventually evolve into the different categories of luminosity of stars. However, stars that are too small and fail to reach the evolution stage become browf dwarfs and die off. Also known as "failed stars" because they fail to start the most basic evolutionary proccess of stellar evolution.
