WebAccording to Wikipedia, the red giant phase begins when the Hydrogen in the stars center is completely converted to Helium. Hydrogen is then fused to Helium in a shell surrounding the inert Helium core. This occurs a few thousand times faster than the earlier phase, so its lifetime is a few thousand times less than the main sequence phase that ...
