1. The source of energy for the main sequence stars is nuclear fusion of hydrogen into helium whereas that in red giant stars and super giant stars is nuclear fusion of helium into carbon. The fusion of helium into carbon produces much less energy as compared to that of hydrogen into helium. This is the basic reason why there are so many more main ...
