Abstract We present the nucleosynthesis of magneto-rotational supernovae (MR-SNe) including neutrino-driven and magneto-rotational-driven ejecta based, for first time, on two-dimensional simulations with accurate neutrino transport. The models analysed here have different rotation magnetic fields, allowing us to explore impact these two key ingredients. transport is critical analyse slightly ne...

Because of their neutron-richness and association with supernovae, postexplosion protoneutron star winds are thought to be a likely astrophysical site for rapid neutron capture nucleosynthesis (the r-process). However, the most recent models of spherical neutrino-driven protoneutron star winds do not produce robust r-process nucleosynthesis for ‘canonical’ neutron stars with a gravitational mas...

We study the nucleosyntheses of the light elements Li and B and the rprocess elements in Type II supernovae in the lights of the progress in neutrino spectrum modeling and the studies of galactic chemical evolution. We investigate the influence of total energy, Eν , and decay time, τν of supernova neutrinos on these two nucleosynthesis processes. Common models of the neutrino spectra are adopte...
