... A one solar mass star will spend 10 billion years on the main sequence. The universe is only 13-14 billion years old. From the formula T = 1/M 2.5 and the sun’s lifetime, we see that a star of 0.9 solar masses should spend 13 billion years on the main sequence. So no stars of lower mass would have h ...
