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…

Exact Mass Conservation in Binary Neutron Star Merger Simulations

Boris Daszuta, Sebastiano Bernuzzi, Joan Fontbuté +4

A long-standing problem in the simulation of neutron star spacetimes is the treatment of vacuum regions outside the stars. The use of an artificial low-density atmosphere is a comm…

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…

Turbulent Dynamo Action in Binary Neutron Star Mergers

Eduardo M. Gutiérrez, David Radice, Jacob Fields +1

Binary neutron star mergers are expected to generate intense magnetic fields that power relativistic and non-relativistic outflows and shape their multimessenger signatures. These…

Turbulence in Magnetised Neutron Stars

William Cook, Raj Kishor Joshi, Sebastiano Bernuzzi +2

The magnetic field configuration in the interior of neutron stars and its stability are open problems and may be impacted by the influence of a turbulent cascade within the star. A…

Thermal Effects in Binary Neutron Star Mergers

Jacob Fields, Aviral Prakash, Matteo Breschi +3

We study the impact of finite-temperature effects in numerical-relativity simulations of binary neutron star mergers with microphysical equations of state and neutrino transport in…
