During the lifetime of a main sequence star, hydrogen fusion in its core provides energy, stabilizing against gravitational collapse. As the star ages, its core temperature and density increase, leading to the activation of different nuclear fusion reactions that alter its composition and structure. These changes ultimately determine the fate of the star as it evolves through its various stages.
