boson star

Etymology
. From being an astronomical object composed of mostly bosons, not a star or stellar remnant in the usual sense.

Noun

 * 1)  A theoretical type of heavenly body composed of a form of boson that is self-repelling, what should be highly dense and bend spacetime in a manner approaching that of a black hole.

Usage notes
This "star" is just an object in space, and not a 'star' that has or once had a fusion core, shining in the sky. The use of "star" is in its sense of an object in the sky.

Hypernyms

 * theoretical bosons that would compose a boson star are dark matter candidates
 * boson stars are candidate dark matter particles

Hyponyms

 * axions are a theoretical boson that may conform to the requirements needed for bosonic components of a boson star
