The smaller the star, the longer it will live.


The core of massive stars has more gravitational pressure on its core, resulting in a faster bombardment of atoms (fusion). This forces the massive star to run out of its fuel quicker and also go through a supernova (if massive enough).

A star with a mass lower than this star will have less gravitational pressure on its core, therefore decreasing the speed and the rate of the particles' bombardment.
