Which consequence occurs when stellar hydrogen fuel depletes, forcing reliance on helium?

💡 Explanation

Gravitational core collapse causes rapid implosion because radiation pressure decreases, therefore the star’s core collapses inward under its own gravity initiating helium fusion after hydrogen burning stops, rather than increased radiation levels due to specific nuclear transitions.
