helium burning | The stage when a star fuses helium into carbon and oxygen. All stars born with more than half a solar mass eventually burn helium. | exothermic fusion process |
helium shell flash | It has been shown that helium shell burning outside a degenerate core is unstable; the helium-burning shell does not generate energy at a constant rate but instead produces energy primarily during short flashes. During a flash, the region just outside the helium-burning shell becomes unstable to convection. The resultant mixing probably leads to the s-process as well as to the upward movement of carbon produced by helium burning. | helium burning |
