What is the approximate mass range of the core remaining after a supernova that results in a Neutron Star?

Answer

Between about 1.4 and 3 solar masses

If the core remaining after the supernova collapse falls within the range of approximately 1.4 to 3 solar masses, neutron degeneracy pressure will halt the collapse, forming a Neutron Star.
