boson star

== English == === Etymology === From boson +‎ star (“celestial body”). From being an astronomical object composed of mostly bosons, not a star or stellar remnant in the usual sense. === Noun === boson star (plural boson stars) (astrophysics) 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 ==== dark matter star (theoretical bosons that would compose a boson star are dark matter candidates) dark matter (boson stars are candidate dark matter particles) ==== Hyponyms ==== axion star (axions are a theoretical boson that may conform to the requirements needed for bosonic components of a boson star) === Anagrams === Boonstras
