Q star

A Q-Star, also known as a gray hole, is hypothetical type of a compact, heavy neutron star with an exotic state of matter. The term Q-Star should not be mistaken for quark star, as the Q does not stand for quark, but rather for a conserved particle number. A Q-Star may be mistaken for a stellar black hole. One such candidate is the compact object in V404 Cyg.

Brands of Q-stars

• SUSY Q-ball^[1]
• B-ball, stable Q-balls with a large baryon number B. They exist in neutron stars that have absorbed Q-ball(s).^[1]
