How can a neutron star be born?

Answer 1

A neutron Star is believed to be the result of a burned out star of a specific mass.

when a star burned out all its fuel then, depending on its size, a few things can happen.
it can explode in a nova
it can collapse into a white dwarf if it was very small
it can collapse into a neutron star
it can collapse into a black hole

what ammount of mass creates which kind of star is a very theoretical issue.
its believed that a star, the size of our sun, would collapse into a white dwarf.
maybe if the sun would be about 1,4 times larger it would turn into a neutron star
i think the mass for a black hole was somewhere about 5(?) times the mass of the sun.

whatever happens if a star runs out of fuel if it collapses or explodes.. it can do in fact both.
what's leftover can create a neutron star if the mass matches

Answer 2

Neutron stars are one of the possible end results of a stars life. If a star is massive enough (but not too massive) and other events play out well, then the star will collapse into a neutron star.

Essentially, the gravity field of such a star is so strong that it collapses the electron fields of the atoms that its made of. When the electrons collapse on the nucleus, it interacts with the protons becoming neutrons, hence the name netron star.

Answer 3

Neutron stars are more analogous to a death than they are to a birth, neutron stars are developed by stars that have expended the material to perform certain types of fission and collapse down to a size that squishes atoms down to the neutron hence the name "Neutron Star".

Answer 4

Transition between a collapsing star and a black hole (in most cases)
Huge stars collapse under their own gravitational pressure and condense to a very small size. They have bright and dark sides.
