How do red giants form
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. A red giant is a luminous giant star of low or intermediate mass (roughly 0.3–8 solar masses (M☉)) in a late phase of stellar evolution. The outer atmosphere is inflated and tenuous, making the radius large and the surface temperature around 5,000 K (4,700 °C; 8,500 °F) or lower. The appearance of the red giant is … See more A red giant is a star that has exhausted the supply of hydrogen in its core and has begun thermonuclear fusion of hydrogen in a shell surrounding the core.
