WebOct 31, 2024 · How a red giant evolves will be largely dependent upon its mass. For low to medium mass stars, such as our sun , the process of nuclear fusion will generally stop with helium. Since the red giant has … WebAgain, a red supergiant forms when the hydrogen supply runs out in the core of a massive star. During this time, the star begins to fuse heavier and heavier elements. The process ceases when the star begins to fuse iron because this requires more energy than it generates. Most super red giants will explode as Type II supernovae when this happens.
