Stellar Evolution of Single Stars Stellar evolution can be divided into 3 distinct phases: 1)Pre-main sequence evolution: a relatively short (~ 107-8 yrs) phase, but involving many complex processes. An active research area. 2)Main sequence phase: the longest phase of a star’s life ~ 1010 yrs for th ...
