AsterX: a new open-source GPU-accelerated GRMHD code for dynamical spacetimes
Jay V. Kalinani, Liwei Ji, Lorenzo Ennoggi +10
We present AsterX, a novel open-source, modular, GPU-accelerated, fully general relativistic magnetohydrodynamic (GRMHD) code designed for dynamic spacetimes in 3D Cartesian coordi…
Modeling Solids in Nuclear Astrophysics with Smoothed Particle Hydrodynamics
Irina Sagert, Oleg Korobkin, Ingo Tews +4
Smoothed Particle Hydrodynamics (SPH) is a frequently applied tool in computational astrophysics to solve the fluid dynamics equations governing the systems under study. For some p…
Modeling Neutron Star Oscillations in a Fixed General Relativistic Background Including Solid Crust Dynamics
Bing-Jyun Tsao, Irina Sagert, Oleg Korobkin +4
Measurements of the gravitational-wave signals from neutron star mergers allow scientists to learn about the interior of neutron stars and the properties of dense nuclear matter. T…
Conservation of Angular Momentum in the Fast Multipole Method
Oleg Korobkin, Hyun Lim, Irina Sagert +5
Smoothed particle hydrodynamics (SPH) is positioned as having ideal conservation properties. When properly implemented, conservation of total mass, energy, and both linear and angu…
Source term method for binary neutron stars initial data
Bing-Jyun Tsao, Roland Haas, Antonios Tsokaros
The initial condition problem for a binary neutron star system requires a Poisson equation solver for the velocity potential with a Neumann-like boundary condition on the surface o…
Hamilton-Jacobi hydrodynamics of pulsating relativistic stars
John Ryan Westernacher-Schneider, Charalampos Markakis, Bing Jyun Tsao
The dynamics of self-gravitating fluid bodies is described by the Euler-Einstein system of partial differential equations. The break-down of well-posedness on the fluid-vacuum inte…
