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…

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…

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…
