Stellar nucleosynthesis - Wikipedia

The term supernova nucleosynthesis is used to describe the creation of elements during the explosion of a massive star or white dwarf. The advanced sequence of burning fuels is driven by gravitational collapse and its associated heating, resulting in the subsequent burning of carbon, oxygen and silicon.
