Boson star

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.^[1]^[2]

Boson stars may have been formed through gravitational collapse during the primordial stages of the big bang.^[3] At least in theory, a supermassive boson star could exist at the core of a galaxy, and it may explain many of the observed properties of active galactic cores.^[4] Boson stars have also been proposed as a candidate dark matter object.^[5]
