Conservative Initial Mapping For Multidimensional Simulations of Stellar Explosions
Ke-Jung Chen, Alexander Heger, Ann Almgren
Mapping one-dimensional stellar profiles onto multidimensional grids as initial conditions for hydrodynamics calculations can lead to numerical artifacts, one of the most severe of…
The Hydrodynamic Origin of Neutron Star Kicks
J. Nordhaus, T. Brandt, A. Burrows +1
We present results from a suite of axisymmetric, core-collapse supernova simulations in which hydrodynamic recoil from an asymmetric explosion produces large proto-neutron star (PN…
High-Resolution Simulations of Convection Preceding Ignition in Type Ia Supernovae Using Adaptive Mesh Refinement
A. Nonaka, A. J. Aspden, M. Zingale +3
We extend our previous three-dimensional, full-star simulations of the final hours of convection preceding ignition in Type Ia supernovae to higher resolution using the adaptive me…
From Convection to Explosion: End-to-End Simulation of Type Ia Supernovae
A. Nonaka, A. S. Almgren, J. B. Bell +3
We present our end-to-end capability for computing the convective phase through the explosion phase of Type Ia supernovae. We compute the convective phase up to the time of ignitio…
Multidimensional Simulations of Thermonuclear Supernovae from the First Stars
Ke-Jung Chen, Alexander Heger, Ann Almgren
Theoretical models suggest that the first stars in the universe could have been very massive, with typical masses 100 \Msun. Many of them might have died as energetic the…
CASTRO: A New Compressible Astrophysical Solver. II. Gray Radiation Hydrodynamics
W. Zhang, L. Howell, A. Almgren +2
We describe the development of a flux-limited gray radiation solver for the compressible astrophysics code, CASTRO. CASTRO uses an Eulerian grid with block-structured adaptive mesh…
