Neutron star

A neutron star is a stellar remnant left after a giant star with too little mass to form a black hole dies. It is dense enough to reach the neutron degeneracy pressure, when the pressure is high enough to combine protons and electrons to form neutrons, and therefore has a mass of greater than 1.4 solar masses (the Chandrasekhar limit).The maximum mass of a neutron star is given by the Tolman–Oppenheimer–Volkoff limit, and is somewhere between 2.0 and 3.0 solar masses. star with too little mass to form a black hole dies.
