Why do higher mass stars live shorter lives on the main sequence than lower mass stars?
A)Higher mass stars burn through their nuclear fuel faster.
B)Lower mass stars don't get their energy from nuclear fusion like higher mass stars do.
C)Higher mass stars have less hydrogen fuel to burn.
D)Lower mass stars spend a longer time evolving to the main sequence.

Question

Quizplus · Accepted Answer

Higher mass stars have a greater gravitational pressure, which creates higher temperatures and pressures in their cores. This causes nuclear fusion to occur at a much faster rate, leading to a faster consumption of their nuclear fuel and a shorter time spent on the main sequence.
