Uncertainties in the production of p nuclides in SN Ia determined by Monte Carlo variations

TL;DR

This paper investigates how nuclear physics uncertainties affect the predicted abundances of p-nuclides in Type Ia supernovae using Monte Carlo simulations on tracer data.

Contribution

It introduces a Monte Carlo post-processing method to quantify the impact of reaction rate uncertainties on p-nuclide production in supernova models.

Findings

Reaction rate uncertainties significantly influence p-nuclide abundance predictions.

Monte Carlo variations identify key nuclear reactions affecting p-nuclide synthesis.

The study provides a quantitative assessment of uncertainties in supernova nucleosynthesis models.

Abstract

Several thousand tracers from a 2D model of a thermonuclear supernova were used in a Monte Carlo post-processing approach to determine p-nuclide abundance uncertainties originating from nuclear physics uncertainties in the reaction rates.
