The star stays in the main sequence stage for a long time.

The star runs out of hydrogen and turns into a planetary nebula or a supernova, depending on its mass.

Heavy elements are created when the supernova explodes.

The temperature increases in the center of a nebula, and nuclei begin to fuse.

Stellar nebula, star, red giant, planetary nebula and then a white dwarf.
