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…
