Animation of the steps listed below: The HR Diagram Stellar Evolution is driven entirely by the never ending battle between Pressure and Gravity . As imbalances are reached, the star is driven to find a new Energy source. Each new stage in stellar evolution is hence marked by a different energy generation mechansism. These stages are discussed below: Structure of a Main Sequence Star Here see ...

M I L K Y - W A Y . C O M Back to main page Stars come to life, they live over a very long period of time - and finally they die. The life of the stars can be very varying; the same applies to their death. Our SUN is one of the small stars. The smallest stars are one tenth of the mass of our sun and the biggest stars are maybe 20 times larger than our Sun. The stars consist of matter that is ...
