Description
Neutrinos can play an important role in the synthesis of nuclides in high energy astrophysical processes involving compact objects, such as core-collapse supernovae or binary neutron star mergers, where neutrinos can experience collective flavor oscillations driven by neutrino-neutrino interactions. Here, we seek to explore the possible influences of neutrino interactions on the heavy-element nucleosynthesis including νp-process and r-process in supernova environments with different astrophysical conditions and neutrino inputs. We find that the potential impact is particularly strong in high-entropy, proton-rich conditions, where neutrino interactions can nudge an initial νp process neutron rich, introducing a new neutrino-induced neutron capture process "νi process".
