Supernova nucleosynthesis is a theory of the production of many different chemical elements in supernova explosions, first advanced by fred hoyle in 1954 [1. In type ia supernovae (sne ia) the relative abundances of chemical elements are affected by the neutron excess in the composition of the progenitor white dwarf.
