compact object

(compact star)
(dense astronomical body such as white dwarf or denser)

A compact object (or compact star) is a general term for small, very massive stellar objects, typically meant to include white dwarves, neutron stars, black holes, and any other hypothesized exotic dense stars. They are typically stellar remnants, what's left after a star's fusion has run out. The term degenerate star is also used for compact objects that are not black holes.

A compact object merger is a merger of two such stars, the source of hypothesized detectable gravitational waves and a luminosity potentially 1015 times that of the Sun.
