What is Compact star?
In [[astronomy]], the term '''compact star''' or '''compact object''' is used to refer collectively to [[white dwarf]]s, [[neutron star]]s, other exotic dense stars, and [[black hole]]s. Most compact stars are at the end of their [[stellar evolution]]. They are called '''stellar remnants''': the form of the remnant depends mainly on the mass of the star when it [[star formation|formed]]. These objects are small for their mass. Astronomic objects with an unknown nature are often called ''compact star'', when evidence suggests that they are very [[mass]]ive and that they have a small [[radius]]. A compact star which is not a black hole is sometimes called a '''degenerate star'''. {{-}} {{physics-stub}} [[Category:Types of stars]]
