What is the approximate solar mass range for a collapsing core to stabilize specifically as a neutron star?

Answer

Between approximately 1.4 and 3 solar masses.

When the collapsing core mass stabilizes in the range between roughly 1.4 and 3 solar masses, the pressure forces protons and electrons together to form neutrons, creating a neutron star supported by neutron degeneracy pressure.
