Abstract

Core-collapse supernovae are considered to produce some kinds of light elements via the neutrino-process and previous studies were limited to Type II supernovae. We demonstrate hydrodynamic simulation of Type Ic supernova (SN Ic) explosions and estimate the amounts of the light elements produced via the neutrino-process and also the subsequent spallation reactions. We find that the neutrino-process in some SN Ic models produces significant amounts of boron and that high-temperature mu- and tau-neutrinos and their anti-neutrinos, reasonably suggested from the compact structure of SN Ic progenitors, enhance the light element production through the neutralcurrent reactions, which may imply an important role of SNe Ic in the Galactic chemical evolution.
