A black hole
A star that has collapsed under gravity and is made of neutrons is called a neutron star. Neutron stars are extremely dense and have a strong gravitational pull due to the collapsed core of a massive star. They are the remnants of supernova explosions.
A cold dead star is called a white dwarf. It is formed when a star has exhausted its nuclear fuel and collapsed under gravity, shrinking to a small, dense, and dim object.
A massive collapsed star is a dead star.
Hotter and dimmer. It's much smaller, but much denser.
This would likely be a black hole, where the intense gravity comes from a mass that has collapsed to a very small size. The gravitational force near a black hole is so strong that not even light can escape, making them invisible. Their extreme gravity can warp spacetime and have significant effects on surrounding matter and light.

It contains the entire collapsed star, however the star has collapsed to an infinitesimal point (or infinitesimally thin ring if its spinning) singularity, leaving everything around that totally empty except for warped spacetime (which is what causes gravity).
black holes are stars which collapsed under their own gravity.

A massive collapsed star is a dead star.
A black hole is what is left of an object that has completely collapsed under the force of gravity.
Hotter and dimmer. It's much smaller, but much denser.
their black and they have tremendous gravity, due to them being a collapsed star that have imploded onto itself.
A neutron star, or in an even more extreme case, a black hole.

You're talking about a so-called "black hole". It doesn't necessarily have any more gravity than a normal star with the same mass has. It's just that if the mass is all crammed into a tiny space, then you can get much closer to it, and THAT's where the gravity is stronger.
A collapsed star is a term used to describe a "dead" star, which is a star that has come to the end of its lifetime and just collapses on itself. A black hole
