What pressure supports a compact object if the collapsing core's mass remains below the threshold required for black hole formation?

Answer

Neutron degeneracy pressure

If the collapsing core's mass stays below the critical threshold (around 2 to 3 solar masses), the object becomes a neutron star supported by the immense pressure exerted by tightly packed neutrons.
