Detailed explanation-1: -Stars generate energy through nuclear fusion.
Detailed explanation-2: -Stars are fueled by the nuclear fusion of hydrogen to form helium deep in their interiors. The outflow of energy from the central regions of the star provides the pressure necessary to keep the star from collapsing under its own weight, and the energy by which it shines.
Detailed explanation-3: -Main sequence stars are characterized by the fusion hydrogen into helium in their cores to produce energy.
Detailed explanation-4: -Main sequence stars are characterised by the source of their energy. They are all undergoing fusion of hydrogen into helium within their cores. The rate at which they do this and the amount of fuel available depends upon the mass of the star.
Detailed explanation-5: -A star’s life cycle is determined by its mass. The larger its mass, the shorter its life cycle. A star’s mass is determined by the amount of matter that is available in its nebula, the giant cloud of gas and dust from which it was born.
