Boson Stars
A boson star is a hypothetical astronomical object that is formed out of particles called bosons (conventional stars are formed out of fermions). For this type of star to exist, there must be a stable type of boson that possesses a small mass. As of 2002 there is no significant evidence that such a star exists. However, it may become possible to detect them by the gravitational radiation emitted by a pair of co-orbiting boson stars.
Boson stars may have been formed through gravitational collapse during the primordial stages of the big bang. At least in theory, a supermassive boson star could exist at the core of a galaxy, which might explain many of the observed properties of active galactic cores. Boson stars have also been proposed as a candidate dark matter object.

Famous quotes containing the word stars:
“I have heard the voice of a hound, just before daylight, while the stars were shining, from over the woods and river, far in the horizon, when it sounded as sweet and melodious as an instrument.”
—Henry David Thoreau (1817–1862)
