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. They have radii tens to hundreds of times larger than that of the Sun. However, their outer envelope is lower in temperature, giving them a yellowish-orange hue. Despite the lower energy density of their envelope, red giants are many times … WebRed giant Helium Burning When the core reaches 100,000,000 K, a new fusion reaction begins triple-alpha process 4 He + 4 He -> 8 Be + energy 8 Be + 4 He -> 12 C + energy (effectively, 3 4 He -> 12 C + energy) at even higher temperatures (like 200,000,000 K) Carbon-helium fusion forms Oxygen 12 C + 4 He -> 16 O + energy
