Neutron star
After a high mass star explodes, the leftover material forms a remnant called a neutron star or a black hole. If the core of the star is less than about 3 times the mass of the Sun, it collapses to form a neutron star. If the core is more massive, it collapses further, causing the gravitational collapse to form a black hole.
