Nucleosynthesis in Early Neutrino Driven Winds

TL;DR

This paper examines nucleosynthesis in early neutrino-driven winds from supernovae, showing that proton-rich winds cannot produce certain molybdenum isotopes and neutron-rich bubbles do not significantly contribute to nucleosynthesis.

Contribution

It provides new insights into the role of nuclear parameters and the limited contribution of neutron-rich bubbles in supernova nucleosynthesis.

Findings

Proton-rich winds cannot produce solar Mo92 and Mo94.

Neutron-rich bubbles do not significantly contribute to nucleosynthesis.

Nuclear parameters critically influence isotope synthesis.

Abstract

Nucleosynthesis in early neutrino winds is investigated. Presented is a brief overview of two recent problems of supernova nucleosynthesis. In the first part we investigate the effect of nuclear parameters on the synthesis of Mo92 and Mo94. Based on recent experimental results, we find that the proton rich winds of the model investigated here can not be the source of solar Mo92 and Mo94. In the second part we investigate the nucleosynthesis from neutron rich bubbles and show that they do not contribute to the overall nucleosynthesis.
