Alpha process nucleosynthesis and sensitivity analysis in SiRoP

Abstract

The r-process nucleosynthesis (in explosive astrophysical events) is responsible for about half of the heavy elements observed in the universe. However, r-process outputs in the literature are difficult to replicate and vary across studies due to differences in nuclear mass models or initial conditions (e.g., seed nuclei). We will review the SiRoP code for $r$-process nucleosynthesis, which now includes an alpha-capture module that allows for a variety of initial conditions and a nuclear sensitivity module to test how changes in nuclear masses affect $r$-process abundance patterns. Additionally, we will examine how different sensitivity metrics influence this behavior.
