pynucastro 3: A community library for nuclear astrophysics
Zhi Chen, Khanak Bhargava, Eric T. Johnson +8
We describe the latest release of pynucastro: a community python library for nuclear astrophysics. The goal of the pynucastro project is to build the tools needed to interactively…
AMReX-Astrophysics Microphysics: A set of microphysics routines for astrophysical simulation codes based on the AMReX library
Astro Microphysics Team, Khanak Bhargava, Abigail Bishop +15
The AMReX-Astrophysics Microphysics library provides a common set of microphysics routines (reaction networks and associated physics, equations of state, and various transport coef…
Multi-dimensional Models of Mixed H/He Flames in X-ray Bursts
Eric T. Johnson, Michael Zingale
We investigate the properties of mixed H/He flames in X-ray bursts using 2D hydrodynamic simulations. We find that as the initial hydrogen abundance of the atmosphere increases, th…
Numerical Treatment of Shock-Induced Nuclear Burning in Double Detonation Type Ia Supernovae
Ryan Brady, Michael Zingale
We present a benchmark problem to assess the treatment of shock-induced nuclear burning in the context of double detonation Type Ia supernovae. In a stratified white dwarf model, w…
Multidimensional Nova Simulations with an Extended Buffer and Lower Initial Mixing Temperatures
Alexander Smith Clark, Michael Zingale
A classical nova is a thermonuclear runaway initiated on a white dwarf accreting solar-like material from its stellar companion. Once the white dwarf accretes enough mass, the pres…
3D Convective Urca Process in a Simmering White Dwarf
Brendan Boyd, Alan Calder, Dean Townsley +1
A proposed setting for thermonuclear (Type Ia) supernovae is a white dwarf that has gained mass from a companion to the point of carbon ignition in the core. In the early stages of…
