Low-Mass Stellar Evolution: Physical Mechanisms

Low- and intermediate-mass stars spend most of their lives fusing hydrogen on the main sequence, then evolve through red-giant and helium-burning phases before losing their envelopes and ending as white dwarfs. Low-mass evolution predicts the future of Sun-like stars, calibrates age dating of populations, explains planetary nebulae and white dwarfs, and supplies chemically enriched gas for later generations.

Core hydrogen depletion removes the original central energy source, allowing the core to contract and heat while hydrogen burns in a surrounding shell.
