What remnant forms if the original star was massive (e.g., $8$ to $20$ solar masses) and the collapse is halted by degeneracy pressure?

Answer

A neutron star.

If the remnant core mass is between approximately 8 and 20 solar masses, the collapse halts due to neutron degeneracy pressure, resulting in an ultra-dense neutron star.
