Supernova nucleosynthesis is a theory of the production of many different chemical elements in supernova explosions, first advanced by Fred Hoyle in 1954. Supernova nucleosynthesis within exploding stars is largely responsible for the elements between oxygen and rubidium: from the ejection of elements produced during stellar nucleosynthesis; through explosive nucleosynthesis during the supernova explosion; and from the r-process (absorption of multiple neutrons) during the explosion.

Pagel’s book (referred to as Pagelhereafter) covers all the topics in these notes, although it puts more emphasis on galactic chemical evolution and somewhat less on the (stellar) nucleosynthesis processes than we do. Supernova nucleosynthesis is a theory of the nucleosynthesis of the natural abundances of the chemical elements in supernova explosions, advanced as the nucleosynthesis of elements from carbon to nickel in massive stars by Fred Hoyle in 1954. There also four types of Nucleosynthesis namely the Big Bang Nucleosynthesis, Stellar Nucleosynthesis, Explosive Nucleosynthesis, and Cosmic ray Spallation. RekamiStworzone Stellar Nucleosynthesis .
