Explanation:
Detailed explanation-1: -Hydrogen fusion (nuclear fusion of four protons to form a helium-4 nucleus) is the dominant process that generates energy in the cores of main-sequence stars.
Detailed explanation-2: -Nuclear Fusion in Stars The enormous luminous energy of the stars comes from nuclear fusion processes in their centers. Depending upon the age and mass of a star, the energy may come from proton-proton fusion, helium fusion, or the carbon cycle.
Detailed explanation-3: -Stars produce their energy by a mechanism called nuclear fusion. In this process two simple elements fuse together to produce a heavier element, releasing a lot of energy. Not to be confused with nuclear fission, the process used in nuclear power plants.
