Compact Stars
Compact stars are astronomical objects that have collapsed under their own gravity, resulting in extremely high densities. The most common types of compact stars include white dwarfs, neutron stars, and black holes. These stars are remnants of larger stars that have exhausted their nuclear fuel and undergone a supernova explosion or other forms of stellar evolution.
White dwarfs are the remnants of low to medium-mass stars, while neutron stars are formed from the collapse of massive stars, resulting in a core primarily composed of neutrons. Black holes represent the ultimate stage of stellar evolution, where gravity is so strong that not even light can escape. Each type of compact star has unique properties and plays a significant role in the universe's lifecycle.
