Question

What do massive stars become?

Answer 1

As the core collapses, the outer layers of the star are expelled. A planetary nebula is formed by the outer layers. The core remains as a white dwarf and eventually cools to become a black dwarf. ... If the remnant of the explosion is 1.4 to about 3 times as massive as our Sun, it will become a neutron star.
