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…
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 He Flames in X-ray Bursts to Nuclear Physics
Zhi Chen, Michael Zingale, Kiran Eiden
Through the use of axisymmetric 2D hydrodynamic simulations, we further investigate laterally propagating flames in X-ray bursts (XRBs). Our aim is to understand the sensitivity of…
Comparing Early Evolution of Flames in X-ray Bursts in Two and Three Dimensions
Michael Zingale, Kiran Eiden, Max Katz
We explore the early evolution of flame ignition and spreading on the surface of a neutron star in three-dimensions, in the context of X-ray bursts. We look at the nucleosynthesis…
pynucastro: A Python Library for Nuclear Astrophysics
Alexander Smith Clark, Eric T. Johnson, Zhi Chen +6
We describe pynucastro 2.0, an open source library for interactively creating and exploring astrophysical nuclear reaction networks. We demonstrate new methods for approximating ra…
Dynamics of Laterally Propagating Flames in X-ray Bursts. II. Realistic Burning & Rotation
A. Harpole, N. M. Ford, K. Eiden +4
We continue to investigate two-dimensional laterally propagating flames in type I X-ray bursts using fully compressible hydrodynamics simulations. In the current study we relax pre…
Preparing Nuclear Astrophysics for Exascale
Max P. Katz, Ann Almgren, Maria Barrios Sazo +7
Astrophysical explosions such as supernovae are fascinating events that require sophisticated algorithms and substantial computational power to model. Castro and MAESTROeX are nucl…
Dynamics of Laterally Propagating Flames in X-ray Bursts. I. Burning Front Structure
Kiran Eiden, Michael Zingale, Alice Harpole +3
We investigate the structure of laterally-propagating flames through the highly-stratified burning layer in an X-ray burst. Two-dimensional hydrodynamics simulations of flame propa…
The Castro AMR Simulation Code: Current and Future Developments
M. Zingale, A. S. Almgren, M. Barrios Sazo +7
We describe recent developments to the Castro astrophysics simulation code, focusing on new features that enable our simulations of X-ray bursts. Two highlights of Castro's ongoing…
Toward Resolved Simulations of Burning Fronts in Thermonuclear X-ray Bursts
M. Zingale, K. Eiden, Y. Cavecchi +9
We discuss the challenges of modeling X-ray bursts in multi-dimensions, review the different calculations done to date, and discuss our new set of ongoing simulations. We also desc…
