White dwarfs with masses greater than the Chandrasekhar limit, the upper limit upon which white dwarfs can resist their own gravity due to the Pauli Exclusion principle.
The currently accepted value of the Chandrasekhar limit is 1.44 solar masses.
BLACK HOLE
A black hole originated as a star, that is, the star converted to a black hole.
A black hole does not create a star. A black hole is formed when a star dies.
Probably not a star. Could be a black hole, asteroid, or other spacial object.
That refers to a black hole - but a black hole is not exactly a star.
Yes. A black hole is a collapsed star.
Yes black hole is last stage of a star
If a star was "too close" to a black hole, that star would be captured by the black hole's gravity and be pulled into it.
No. A black hole may be the remnant of the core of what was once a blue star, but the black hole itself is as black as anything can possibly be.
A black hole is a collapsed star with such a strong gravitational pull that not even light can escape from it. This phenomenon occurs when a massive star runs out of nuclear fuel and collapses under its own gravity. The boundary surrounding a black hole, beyond which nothing can escape, is called the event horizon.
A black hole is the stellar remains of a massive star.
No, black holes cannot turn into neutron stars. Neutron stars form from the remnants of supernova explosions of massive stars, while black holes are formed from the gravitational collapse of massive stars. Once a black hole is formed, it will remain a black hole and will not transform into a neutron star.
