Leaving Main Life Sequence. When a massive star has expended all of its core hydrogen, this means that the gravitational forces pushing inward will overcome the fusion forces which had been pushing outward. The outer layers of the star will then compact inwards.
Main sequence stars fuse hydrogen atoms to form helium atoms in their cores. About 90 percent of the stars in the universe, including the sun, are main sequence stars.These stars can range from about a tenth of the mass of the sun to up to 200 times as massive.ain sequence stars fuse hydrogen atoms to form helium atoms in their cores. About 90 percent of the stars in the universe, including the sun, are main sequence stars.
