Kinds of stellar nucleosynthesis :

• explosive nucleosynthesis (3 facts) - The nucleosynthetic processes which are thought to occur in supernovae. These explosive processes are thought to produce the nuclei from neon up to and including the e-process nuclei and possibly the r-process nuclei. Explosive carbon burning occurs for a temperature of about 2 × 10⁹ K and a density of 10⁴-10⁷ g cm^-3 and produces nuclei from neon to silicon. Explosive oxygen burning occurs for a temperature of about 4 × 10⁹ K and produces nuclei from silicon to calcium, and the e-process occurs at a temperature greater than 5 × 10⁹ K and produces the iron peak nuclei., The nucleosynthesis processes that are believed to occur in supernovae. Explosive carbon burning occurs at a temperature of about 2 × 10⁹ K and produces the nuclei from neon to silicon. Explosive oxygen burning occurs near 4 × 10⁹ K and produces nuclei between silicon and calcium in atomic weight. At higher temperatures, still heavier nuclei, up to and beyond iron, are produced.
