An HLLD Implementation for General Relativistic Magnetohydrodynamics in AthenaK
Jacob Fields, George N. Wong, James M. Stone
We present an implementation of an HLLD approximate Riemann solver for the AthenaK astrophysics code with support for full general relativistic magnetohydrodynamics via a tetrad fr…
Finite-Solid-Angle Boltzmann Radiation Transport on Dynamical Spacetimes in AthenaK
Hengrui Zhu, Alexander J. Dittmann, Lizhong Zhang +3
We extend the finite-solid-angle general relativistic radiation transport method of C. J. White et al. (2023) to time-dependent spacetimes represented in ADM form. This Valencia-ty…
Turbulent Dynamo Action in Binary Neutron Star Mergers
Eduardo M. Gutiérrez, David Radice, Jacob Fields +1
We perform general-relativistic magnetohydrodynamics zoom-in simulations of the merger of two neutron stars starting with pulsar-like realistic initial magnetic field. We employ un…
Performance-Portable Binary Neutron Star Mergers with AthenaK
Jacob Fields, Hengrui Zhu, David Radice +4
We introduce an extension to the AthenaK code for general-relativistic magnetohydrodynamics (GRMHD) in dynamical spacetimes using a 3+1 conservative Eulerian formulation. Like the…
