However, the interior may vary with respect to the location of the layers. Stars like the Sun and those less massive than the Sun have the layers in the order described above. Stars that are several times more massive than the Sun have convective layers deep in their cores and radiative outer layers. In contrast, stars that are intermediate between the Sun and the most massive stars may only have a radiative layer. Life on the Main Sequence Stars on the main sequence burn by fusing hydrogen into helium.
Large stars tend to have higher core temperatures than smaller stars.
Therefore, large stars burn the hydrogen fuel in the core quickly, whereas, small stars burn it more slowly. The length of time that they spend on the main sequence depends upon how quickly the hydrogen gets used up. What happens once the hydrogen in the core is gone depends upon the mass of the star. Inc.
