===Boson star===
A [[boson star]] is a hypothetical [[astronomical object]] that is formed out of particles called [[boson]]s (conventional [[star]]s are formed out of [[fermion]]s). For this type of star to exist, there must be a stable type of boson with repulsive self-interaction. As of 2016 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.<ref>{{cite book
