A Fully Explicit Integrator for Modeling Astrophysical Reactive Flows
Parker Johnson, Michael Zingale, Eric T. Johnson +2
Simulating complex astrophysical reacting flows is computationally expensive -- reactions are stiff and typically require implicit integration methods. The reaction update is often…
A Framework for Exploring Nuclear Physics Sensitivity in Numerical Simulations
Zhi Chen, Eric T. Johnson, Max Katz +3
We describe the AMReX-Astrophysics framework for exploring the sensitivity of astrophysical simulations to the details of a nuclear reaction network, including the number of nuclei…
pynucastro 2.1: an update on the development of a python library for nuclear astrophysics
Alexander Smith Clark, Eric T. Johnson, Zhi Chen +5
pynucastro is a python library that provides visualization and analyze techniques to classify, construct, and evaluate nuclear reaction rates and networks. It provides tools that a…
Sensitivity of Simulations of Double Detonation Type Ia Supernova to Integration Methodology
Michael Zingale, Zhi Chen, Melissa Rasmussen +4
We study the coupling of hydrodynamics and reactions in simulations of the double detonation model for Type Ia supernovae. When assessing the convergence of simulations, the focus…
