High Mass Stellar Evolution — Quiz

Question 9 • Physics in the Universe

Why do high-mass stars undergo more rapid life cycles than low-mass stars?

Answer
A
Their cores do not reach high enough temperatures for fusion.
B
They start with less fuel available.
C
They burn through fuel at a much faster rate due to stronger gravity.
D
They exist in regions with less stellar dust.

Explanation

A high-mass star’s stronger gravity compresses its core more intensely, creating higher temperatures and pressure. This makes nuclear fusion happen much faster, so the star uses up its fuel sooner despite starting with more fuel than a low-mass star. Therefore, high-mass stars have more rapid life cycles because they burn through fuel faster.
