helium flash

(helium ignition in a star)

A helium flash is the fast fusion of helium in a star. It can be a helium core flash (aka just core flash) when the core of a red giant gains enough helium and heat to fuse, or a helium shell flash (aka just shell flash, i.e., helium runaway shell) when a layer of an active galactic nucleus gains the necessary helium and heat.
