How is the lifetime of a star related to its mass?

Question

Quizplus · Accepted Answer

The lifetime of a star is inversely proportional to its mass. This means that more massive stars use up their fuel much faster and hence have shorter lifetimes compared to less massive stars. This is because the higher the mass of a star, the higher its core temperature and pressure, which leads to faster fusion reactions and depletion of fuel. Therefore, more massive stars have shorter lifetimes.
