It's hard to know ahead of time for certain what remnant a massive star will leave at the end of its life, since it might shed a large fraction of its gaseous envelope; but mass is a fairly good guide. A remnant under about 1.4 solar masses would likely leave a white dwarf, heavier than that it might create a neutron star, up to somewhere around three to five solar masses, beyond that, it might collapse to a black hole. Some studies indicate that before the star dies, it might need to start out with at least eight to ten solar masses to possibly end up as a black hole.
No. A black hole will remain a black hole. A neutron star is a remnant of a star not massive enough to become a black hole.
A black hole.
When the gravity of a neutron star overcomes the degeneracy pressure of the neutrons, the neutron star collapses into a black hole.
There is an upper limit to the mass of neutron stars because if the neutron star is too massive, neutrons would be crushed by the gravity of the neutron star, and the neutron star would collapse into a black hole.
yes, it sure is. (if the core is massive enough.) if not, it becomes a Neutron Star.
Some massive stars will become neutron stars. When massive stars die they will either become neutron stars or black holes depending on how much mass is left behind.
No. A black hole will remain a black hole. A neutron star is a remnant of a star not massive enough to become a black hole.
A black hole.
Both are the collapsed remnants of massive stars.
The Sun probably won't turn into a black hole. What determines whether a certain star becomes a black hole is basically the amount of mass left over, once the star runs out of energy. Less massive stars turn into white dwarves; more massive stars into neutron stars; and the most massive of all, into black holes.
When the gravity of a neutron star overcomes the degeneracy pressure of the neutrons, the neutron star collapses into a black hole.
Mostly in galaxies, where they can form Super Massive Black Holes.

The core contracts and becomes a black hole.
