If a star's temperature increases in its interior, then more nuclear reactions will occur to push the star outward and its temperature will drop, causing the star to contract and eventually return to equilibrium.

Question

Quizplus · Accepted Answer

When the temperature in a star's interior increases, it causes an increase in the rate of nuclear reactions, which in turn increases the pressure outward. This expansion cools the star, reducing the rate of nuclear reactions, and gravity will cause the star to contract until hydrostatic equilibrium is re-established.
