A star becomes a giant after all the hydrogen available for fusion at its core has been depleted and, as a result, leaves the main sequence. The behaviour of a post-main-sequence star depends largely on its mass. For a star with a mass above about 0.25 solar masses (M☉), once the core is depleted of hydrogen it contracts and heats up so that hydrogen starts to fuse i… WebJul 1, 2024 · The larger stars in this sequence (high luminosity, high temperature) undergo rapid fusion reactions.
