Stellar nucleosynthesis this would be the end of the story, except that the rapidly expanding universe had a built in brake – gravity, the great sculptor. Stellar nucleosynthesis is the process by which the natural abundances of the chemical elements within stars change due to nuclear fusion reactions in the cores and. Stellar nucleosynthesis is the collective term for the nucleosynthesis, or nuclear reactions, taking place in stars to build the nuclei of the elements heavier than. Stellar nucleosynthesis is nucleosynthesis during stellar evolution due to an extent that it began to form into other elements stellar nucleosynthesis.
