What makes a supernova a black hole or neutron star?

Answer 1

When a supernova becomes massive enough, it's own gravitational pull will pull it together, and it becomes a neutron star. A neutron is when the electrons in the atoms get pushed against the nucleus because the gravitational pull is so strong. A neutron star becomes a black hole when the individual particles (the electrons, neutrons, and protons) collapse into themselves.

Answer 2

I believe it can become either. The critical factor is, how much mass is left after the supernova explosion.

Answer 3

In rare and extreme cases, a neutron star could collapse into a black hole if it accretes enough matter to push it over the limit. This would only occur under extreme conditions within a pair of binary neutron stars.

Answer 4

It takes more than one hundred billion years for this to happen. Nebulae are like mothers to stars. This is all in the star's life. Stars have their births, live in their lives, and then dies. before black holes are supernovas. After that is a black hole.

Answer 5

Red Giants, under normal circumstances, cannot become a black hole. Red Giants do not have enough mass to become a black hole. Instead, when Red Giants run out of helium to fuse, they're so large their outer envelope starts being blown away by stellar winds into a planetary nebula with a white dwarf (The remnant core of the star) in the middle.

Perhaps you mjean a red supergiant? Usually supergiants become massive enough that they implode in a type II supernova. If the remnant core exceeds 1.4 solar masses (Chandrasekhar limit), it will continue to collapse into a neutron star. If at that point, the remnant exceeds 1.5-3 solar masses (Tolman-Oppenheimer-Volkoff limit), it will continue collapsing into a black hole (Theoretically a quark star, then a black hole).

Answer 6

Only very massive stars can form black holes. In their final years, such stars will fuse heavier and heavier elements. When they start fusing iron the process will absorb rather than release energy. Thermal pressure will stop supporting the star's core against gravity, so the core will collapse. If the core is massive enough then nothing will be able to stop the collapse, and a black hole will form. Not all of the collapsing star will be able to fit across the vent horizon at once. so the collapse will generate a shock wave that blows the star apart.

Answer 7

The primary factor is the initial mass of the star. We're not exactly certain what happens when the star's mass is very close to the limit, but above it, the star will become a black hole, while below the limit the star will become a neutron star or, more probably a pulsar.
