How do the stars die?

When the huge reserves of nuclear fuel are exhausted, the stars die. Just burn all the hydrogen - helium begins to burn. When helium ends, the star uses all its nuclear energy and either explodes or cools. How long this process will last depends on the size of the stars. Largest stars have large amounts of nuclear fuel, but burn quickly. In small eyes, the stock is smaller, but they stretch it for a long time. The stars, twice the Sun, live 10 times less. The greatest dawns live for a few million years.
