Nonlinear evolution of r-modes in rotating relativistic stars
Jose A. Font, Nikolaos Stergioulas
A numerical study of nonlinear r-modes in isentropic, rapidly rotating relativistic stars, via 3-D general-relativistic hydrodynamical evolutions, is presented. On dynamical timesc…
Riemann Solvers in General Relativistic Hydrodynamics
J. M. Ibanez, M. A. Aloy, J. A. Font +3
Our contribution concerns with the numerical solution of the 3D general relativistic hydrodynamical system of equations within the framework of the 3+1 formalism. We summarize the…
Numerical simulations of relativistic wind accretion on to black holes using Godunov-type methods
Jose A. Font, Jose M. Ibanez, Philippos Papadopoulos
We have studied numerically the so-called Bondi-Hoyle (wind) accretion on to a rotating (Kerr) black hole in general relativity. We have used the Kerr-Schild form of the Kerr metri…
General Relativistic Hydrodynamics with Special Relativistic Riemann Solvers
Jose A. Pons, Jose A. Font, Jose M. Ibanez +2
We present a general and practical procedure to solve the general relativistic hydrodynamic equations by using any of the special relativistic Riemann solvers recently developed fo…
