Overview

helium shell flash


Show Summary Details

Quick Reference

A cycle of unstable nuclear burning in asymptotic giant branch stars. It occurs when helium is being burnt in a thin shell around the star's core, and results from the strong dependence of the rate of energy generation on temperature. Any overheating causes considerable expansion followed by collapse, thus setting up large-scale pulsations.
