WebRed Giant A red giant forms after a star has run out of hydrogen fuel for nuclear fusion, and has begun the process of dying. A star maintains its stability through a fine balance between its own gravity, which holds it together, and the outwards pressure from ongoing thermonuclear fusion processes taking place at its core.
