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 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…
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…
