A positivity-preserving adaptive-order finite-difference scheme for GRMHD
Nils Deppe, Lawrence E. Kidder, Saul A. Teukolsky +6
We present an adaptive-order positivity-preserving conservative finite-difference scheme that allows a high-order solution away from shocks and discontinuities while guaranteeing p…
SpECTRE: A Task-based Discontinuous Galerkin Code for Relativistic Astrophysics
Lawrence E. Kidder, Scott E. Field, Francois Foucart +11
We introduce a new relativistic astrophysics code, SpECTRE, that combines a discontinuous Galerkin method with a task-based parallelism model. SpECTRE's goal is to achieve more acc…
Magnetic effects on the low-T/|W| instability in differentially rotating neutron stars
Curran D. Muhlberger, Fatemeh Hossein Nouri, Matthew D. Duez +6
Dynamical instabilities in protoneutron stars may produce gravitational waves whose observation could shed light on the physics of core-collapse supernovae. When born with sufficie…
Black hole-neutron star mergers: effects of the orientation of the black hole spin
Francois Foucart, Matthew D. Duez, Lawrence E. Kidder +1
The spin of black holes in black hole-neutron star (BHNS) binaries can have a strong influence on the merger dynamics and the postmerger state; a wide variety of spin magnitudes an…
Equation of state effects in black hole-neutron star mergers
Matthew D. Duez, Francois Foucart, Lawrence E. Kidder +2
The merger dynamics of a black hole-neutron star (BHNS) binary is influenced by the neutron star equation of state (EoS) through the latter's effect on the neutron star's radius an…
