Student A:Context: A group of Puritans known as the Pilgrims arrived on the Mayflower from England and the Netherlands to establish Plymouth Colony in modern-day Massachusetts, the second successful English colony in North America, following Jamestown, Virginia. About half of the one hundred-plus passengers on the Mayflower died that first winter, mostly because of diseases contracted on the voyage followed by a harsh winter. In 1621, an Indian named Squanto taught the colonists how to grow corn and where to catch eels and fish. His assistance was invaluable and helped the Pilgrims to survive the early years of the colonization. The Pilgrims lived on the same site where Squanto's Patuxet tribe had established a village before they were wiped out from diseases.

Student A: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?
Student B:
OK... The important part for answering this question is: In general, the more massive a star is, the shorter its lifespan on the main sequence.
the more massive a star is , the shorter its lifespan on the main sequence.
