Subject: Exploration of Nucleosynthesis in Low Mass Supernovae

In the low mass supernovae (~8 times solar masses), the shocked ejecta from the protoneutron star undergoing extremely high temperature and density enhances the production of heavy elements (A>56). We find that even in environments with equal number of protons and neutrons, some proton-rich nuclei could be synthesized in significant amounts compared to the solar abundance. When the neutrino interactions on light nuclei are taken into consideration, the protons and neutrons from the spallation reactions were observed to further improve the yields of heavy nuclei.
