Figure 23. H-Burning "Thermostat"

Assume something causes the Sun's internal temperature (T) to drop slightly.

(For example, there is a decrease in the hydrogen fuel supply).

What happens next if the temperature decreases slightly?

Let	Then
E = Energy Production Rate T = Temperature P = Gas Pressure Con = Core Contraction Exp = Core Expansion
Result is Sun maintains equilibrium
