The occurrence of a degenerate core causes them to increase temperature very rapidly while maintaining their volumes, which results in the "helium flash," after which convert three helium nuclei to a carbon-12 nucleus via a Beryllium intermediate in the triple alpha process.

Eventually, their outer regions expand to form a planetary nebula, after which they become white dwarves. For 10 points, identify these stars exemplified by Arcturus, whose cool temperatures are the cause of their namesake color.
