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.
Supernova is nothing but a stellar explosion. To put in other words, it is actually an explosion of a star. 2. So massive is the explosion that for a brief amount of time, the explosion actually outshines the entire galaxy in which it explodes.he amount of energy radiated in one supernova explosion is equal to the amount of energy that is radiated by our Sun so far plus the energy that it will radiate for the rest of its life. 4. A supernova is so bright that it literally takes weeks and sometimes months for the brightness to fade away. 5.
