WebNeutron stars are all between about 1.2 and 3 times the mass of the sun, any larger and they become black holes. A neutron star can be at most about three times the mass of the sun, black holes are nearly all larger than that, so the gravitational pull of the black-hole is greater. Do neutron stars die? A neutron star does not evolve. WebHow hot is a dying neutron star? A neutron star does not generate any light or heat of its own after its formation. Over millions of years its latent heat will gradually cool from an intial 600,000 degrees Kelvin (1 million degrees Fahrenheit) , eventually ending its life as the cold, dead remnant of a once-glorious star.
