Question

One might imagine that if energy generation by nuclear fusion were to increase in a star, this would heat the gas, which would in turn increase the rate of nuclear fusion, and so forth in a runaway cycle of increasing temperature. What process acts in a normal main-sequence star to prevent this behavior?

Answer 1

Answer:

Explanation:

Increased energy generation will cause a temperature increase which will eventually cause expansion and hence cooling of the gas. This slows down the nuclear fusion.
