Binary Evolution Theory

Binary Evolution Theory explains how two stars in a binary system (orbiting each other) evolve over time. When one star exhausts its nuclear fuel, it can expand into a red giant and transfer material to its companion, affecting both stars’ lifecycles. This interaction can lead to phenomena such as novae or even the formation of neutron stars and black holes. The theory helps astronomers understand stellar evolution, the formation of different astronomical objects, and the dynamics of star systems, providing insights into the life cycles of stars and their ultimate fates.
