Which outcome occurs when stellar core hydrogen fuel depletion occurs?

💡 Explanation

Helium fusion begins because the core contracts under gravity, raising the temperature via the virial theorem. This allows Helium fusion in some stars since gravitational contraction heats it to overcome the coulomb barrier; helium, rather than carbon, is next because it has lower fusion energy.
