What is the relationship between a star's mass and its main sequence characteristics?
Answer
More massive stars have hotter cores, are more luminous, and have shorter lifespans.
Mass is the primary determinant; greater mass results in hotter cores and higher luminosity, causing the star to consume its fuel supply much more quickly.
