Stellar remnants are the leftover cores of stars that have exhausted their nuclear fuel. Depending on the mass of the original star, these remnants can take different forms, such as white dwarfs, neutron stars, or black holes. Each type represents a different stage in the life cycle of a star, shaped by its mass and the processes it underwent during its evolution. When a massive star reaches the end of its life, it may explode in a supernova, leaving behind a neutron star or black hole. In contrast, smaller stars shed their outer layers gently, leaving a white dwarf. These remnants provide valuable insights into the life cycles of stars and the dynamics of the universe.
