Answer:

Hey there

When a white dwarf reaches 1.4 solar masses it implodes and becomes a neutron star. this mass limit is known as the "Chandrasekhar limit". It occurs when electron degeneracy pressure (the force that keeps the star from collapsing) is no longer strong enough to hold up aggainsed gravity.
