Neutron star evolution with the Bemfica-Disconzi-Noronha-Kovtun viscous hydrodynamics framework
Harry L. H. Shum, Fernando Abalos, Yago Bea +3
The recently proposed first-order viscous relativistic hydrodynamics formulation by Bemfica, Disconzi, Noronha, and Kovtun (commonly known as the BDNK formulation) has been shown t…
Nonlinear Stability of Rotating Hairy Black Holes
Juan A. Carretero, Philippe Grandclément, Carlos Palenzuela +1
Rotating hairy black holes (RHBHs) are axisymmetric equilibrium solutions of the Einstein--Klein--Gordon equations, consisting of a spinning black hole surrounded by a toroidal dis…
Impact of magnetic field gradients on the development of the MRI: Applications to binary neutron star mergers and proto-planetary disks
T. Celora, C. Palenzuela, D. Viganò +1
The magneto-rotational instability (MRI) is widely believed to play a central role in generating large-scale, poloidal magnetic fields during binary neutron star mergers. However,…
MHDuet : a high-order General Relativistic Radiation MHD code for CPU and GPU architectures
Carlos Palenzuela, Miguel Bezares, Steven Liebling +12
We present MHDuet, an open source evolution code for general relativistic magnetohydrodynamics with neutrino transport. The code solves the full set of Einstein equations coupled t…
Robustness of Magnetic Field Amplification in Neutron Star Mergers
Ricard Aguilera-Miret, Jan-Erik Christian, Stephan Rosswog +1
The dynamics of a binary neutron stars merger is governed by physics under the most extreme conditions, including strong spacetime curvature, ultra-high matter densities, luminous…
Implications of Magnetic Flux-Disk Mass Correlation in Black Hole-Neutron Star Mergers for GRB sub-populations
Manuel R. Izquierdo, Carlos Palenzuela, Steven Liebling +2
We perform numerical relativity simulations of black hole-neutron star (BH-NS) mergers with a fixed mass ratio of , varying the BH spin to produce a wide range of post-merge…
