What happens if the core temperature of a main sequence star momentarily increases slightly?
Answer
Fusion speeds up, causing expansion that slows the rate back down
A temporary increase in core temperature speeds up fusion, creating a surge in outward pressure causing slight expansion. This expansion lowers core density, which slows the fusion rate back down, restoring the original balance.
