Ans: the more massive a star is , the shorter its lifespan on the main sequence
Ques: In general, the more massive a star is, the shorter its lifespan on the main sequence. After the hydrogen fuel at the core has been consumed, the star evolves away from the main sequence on the HR diagram. The behavior of a star now depends on its mass, with stars below 0.23 M becoming white dwarfs directly, whereas stars with up to ten solar masses pass through a red giant stage. More massive stars can explode as a supernova, or collapse directly into a black hole.

Answer this question: how does a main-sequence star's lifetime depend on its overall mass?
CoT: The important part for answering this question is: In general, the more massive a star is, the shorter its lifespan on the main sequence.
