  • We present a nucleosynthesis calculation of a 25 M-circle dot star of solar composition that includes all relevant isotopes up to polonium. We follow the stellar evolution from hydrogen burning till iron core collapse and simulate the explosion using a `piston` approach. We discuss the influence of two key nuclear reaction rates, C-12(alpha, gamma)O-16 and Ne-22(alpha, n)Mg-25, on stellar evolution and nucleosynthesis. The former significantly influences the resulting core sizes (iron, silicon… CONTINUE READING
