Stellar Black Hole

A stellar black hole is a type of black hole that is formed from the remnants of a massive star that has undergone gravitational collapse. When a massive star exhausts its nuclear fuel, it can no longer support its own mass against the force of gravity, causing it to collapse under its own gravity and form a black hole.

Formation of Stellar Black Holes

When a massive star runs out of nuclear fuel, it can no longer produce enough energy to counteract the force of gravity. The outer layers of the star are then expelled in a supernova explosion, while the core undergoes further collapse to form a black hole. The gravitational pull of the collapsed core becomes so strong that not even light can escape from it, resulting in the formation of a black hole.

Characteristics of Stellar Black Holes

Stellar black holes are characterized by their immense gravitational pull and the presence of an event horizon, which is the boundary beyond which nothing can escape the black hole's gravitational pull. They also have a singularity at their center, which is a point of infinite density and zero volume.
