After helium burning concludes, what typically happens to the core fusion process in a star similar to the Sun (Red Giant)?

Answer

Fusion effectively ceases after helium burning.

For stars similar to the Sun, the core cannot achieve the necessary temperatures to ignite carbon fusion after the helium burning phase concludes, resulting in an inert carbon-oxygen core.
