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.
OVERVIEW. Supernova remnants are the dramatic objects produced by the violent explosion of a massive star at the end of its life. This explosion, called a supernova, is one of the most energetic events in the universe, and causes a single star to briefly outshine the entire galaxy in which it is located.he Big Bang produced very little material besides hydrogen and helium, yet we know that most of our planet is composed of other elements. These other elements were produced inside stars and during supernova explosions, and were disbursed into the interstellar medium by supernova remnants.
