Which of the following properties describes a low- mass star?
A)has higher main- sequence luminosities than high mass stars
B)ends its life as a supernova
C)late in life, fuses carbon into oxygen
D)has longer lifetimes than high mass stars

Question

Quizplus · Accepted Answer

Low-mass stars have longer lifetimes than high-mass stars because they fuse their fuel more slowly. High-mass stars also have higher main-sequence luminosities and end their lives as supernovae, while low-mass stars fuse hydrogen into helium and later fuse helium into carbon and oxygen. Therefore, the only property that describes a low-mass star is having longer lifetimes compared to high-mass stars.
