Stellar evolution occurs when a star loses its energy from continuous nuclear fusion reactions, causing instability due to decreasing gas pressure. In order to maintain stability, the star burns fuel in its core until it is depleted, causing the core to collapse into, depending on whether the star is low- or high-mass, either a dense white dwarf, a neutron star, or a black hole.
