Transport Properties of the MRI in Differentially Rotating Neutron Stars
Harshraj Bandyopadhyay, Peter Hammond, David Radice
We perform three-dimensional, high-resolution, general-relativistic magnetohydrodynamics (GRMHD) simulations of the magnetorotational instability (MRI) in differentially rotating n…
GR-Athena++: Binary Neutron Star Merger Simulations with Neutrino Transport
Boris Daszuta, Sebastiano Bernuzzi, Maximilian Jacobi +4
We present general-relativistic radiation magnetohydrodynamics simulations of binary neutron star mergers performed with GR-Athena++. Neutrino transport is treated using a moment-b…
Magnetic Field Configurations in Binary Neutron Star Mergers II: Inspiral, Merger and Ejecta
William Cook, Eduardo M. Gutiérrez, Sebastiano Bernuzzi +6
We perform a series of simulations of magnetised Binary Neutron Star mergers, with varying magnetic field topologies in the initial data, as well as varying Equations of State, and…
Magnetic Flux Emergence in Binary Neutron Star Remnants
Jacob Fields, David Radice, Peter Hammond
Using high-resolution AthenaK simulations of a twisted toroidal flux tube, we study the flux emergence of magnetic structures in the shear layer of a hot massive neutron star typic…
Magnetic Field Configurations in Binary Neutron Star Mergers I: Post-merger Remnant and Disk
Eduardo M. Gutiérrez, William Cook, David Radice +6
We present a suite of general relativistic magnetohydrodynamic (GRMHD) simulations of binary neutron star (BNS) mergers performed with the code GR-Athena++. We investigate how a di…
Numerical relativity simulations of compact binaries: comparison of cell- and vertex-centered adaptive meshes
Boris Daszuta, William Cook, Peter Hammond +4
Given the compact binary evolution problem of numerical relativity, in the finite-difference, block-based, adaptive mesh refinement context, choices must be made on how evolved fie…
GR-Athena++: General-relativistic magnetohydrodynamics simulations of neutron star spacetimes
William Cook, Boris Daszuta, Jacob Fields +5
We present the extension of GR-Athena++ to general-relativistic magnetohydrodynamics (GRMHD) for applications to neutron star spacetimes. The new solver couples the constrained tra…
Neutrino trapping and out-of-equilibrium effects in binary neutron star merger remnants
Pedro Luis Espino, Peter Hammond, David Radice +5
We study out-of-thermodynamic equilibrium effects in neutron star mergers with 3D general-relativistic neutrino-radiation large-eddy simulations. During merger, the cores of the ne…
