If a star's fusion suddenly slowed, what would happen according to the inherent feedback mechanism?

Answer

The core would compress, causing it to heat up and accelerate fusion back toward equilibrium

If fusion slows, outward pressure drops, gravity compresses the core, which heats it up, ironically accelerating the fusion rate back towards the required equilibrium.
