# Asymmetric Nuclear Light Clusters In Supernova Matter

## TL;DR

This paper investigates the role of light nuclear clusters, especially unstable isotopes like H4, in supernova core collapse, highlighting their impact on neutrino interactions and stellar dynamics.

## Contribution

It introduces the consideration of unstable isotope H4 in supernova matter models, emphasizing its influence on neutrino processes and core collapse dynamics.

## Key findings

- Light clusters have a minor effect on thermodynamic quantities.
- Neutrino heating and neutronization are significantly affected by light clusters.
- Pressure changes due to clusters are minimal, but neutrino interactions are impacted.

## Abstract

We explore the appearance of light clusters at high densities of collapsing stellar cores. Special attention is paid to the unstable isotope H4, which was not included in previous studies. The importance of light clusters in the calculation of rates for neutrino matter interaction is discussed. The main conclusion is that thermodynamic quantities are only weakly sensitive to the chemical composition. The change in pressure and hence the direct change in collapse dynamics will be minor. But the change in neutrino heating and neutronization processes can be significant.
