Astronomers from Pennsylvania State University described Chandra's detection of more than 1,000 young stars in the Orion Nebula, including some objects so small that they may fail to reach stardom and wind up as brown dwarfs, stellar objects not large enough to have nuclear furnaces.
Many known extrasolar planets are many times the mass of Jupiter, approaching that of stellar objects known as "brown dwarfs".
Is it really small enough to be a planet, or is it a more massive object such as a brown dwarf, a stellar object too small to produce energy by nuclear reactions?
Brown dwarfs are stellar underachievers.
The process of further shrinkage with increasing mass would continue until appreciable stellar ignition is achieved as in high-mass brown dwarfs having around 50 Jupiter masses.
"Not to take anything away from Big Brown that day because it was a stellar performance.
At the end of the stellar age, galaxies will be composed of compact objects: brown dwarfs, white dwarfs that are cooling or cold ("black dwarfs"), neutron stars, and black holes.
