Abstract

Stars with mass more than about 10 M⊙ are known to culminate their evolution as supernova explosion and a huge number of neutrinos should be emitted from the collapsing core. Previous studies for Type II supernovae have revealed that a fraction of the neutrinos can interact with stellar material and induce some characteristic nucleosynthesis of light elements ( ⁷Li, ¹¹B, ¹⁹F) and heavy elements ( ¹³⁸La, ¹⁸⁰Ta). We studied the neutrino-processed nucleosynthesis in Type Ib(c) supernovae whose progenitors have lost their H-rich (and He) envelopes before explosions. We found that Type Ib/c supernovae can produce ¹¹B as much as Type II supernovae.
