Helium flash - Wikipedia

WebA helium flash is a very brief thermal runaway nuclear fusion of large quantities of helium into carbon through the triple-alpha process in the core of low mass stars (between 0.8 solar masses ( M☉) and 2.0 M☉ [1]) during their red giant phase (the Sun is predicted to experience a flash 1.2 billion years after it leaves the main sequence ). fancy entry table
