What pressure halts the collapse of the core to form a neutron star?

Answer

Neutron degeneracy pressure

The collapse of the core into a neutron star is halted when protons and electrons are squeezed together to form neutrons, and the resistance provided by these tightly packed neutrons, known as neutron degeneracy pressure, stabilizes the remnant.
