Supernova nucleosynthesis. Supernova nucleosynthesis is a theory of the production of many different chemical elements in supernova explosions, first advanced by Fred Hoyle in 1954. The nucleosynthesis, or fusion of lighter elements into heavier ones, occurs during explosive oxygen burning and silicon burning processes. Those fusion reactions create the elements silicon, sulfur, chlorine, argon, sodium, potassium, calcium, scandium, titanium and iron peak elements: vanadium, chromium, manganese, iron, cobalt, and nickel.
How are light and heavy elements formed? (Advanced) Was the Sun made in a supernova? (Intermediate) Can we harvest H & O from space to make water? (Intermediate) Can superheavy elements (such as Z=116 or 118) be formed in a supernova? Can we observe them? (Advanced) What happens to the helium formed in the Sun? (Beginner)
