Axisymmetric Bondi-Hoyle accretion onto a Schwarzschild Black Hole: shock cone vibrations
F. D. Lora-Clavijo, F. S. Guzman
We study numerically the axisymmetric relativistic Bondi-Hoyle accretion of a supersonic ideal gas onto a fixed Schwarzschild background space-time described with horizon penetrati…
Revisiting spherically symmetric relativistic hydrodynamics
F. S. Guzman, F. D. Lora-Clavijo, M. D. Morales
In this paper we revise two classical examples of Relativistic Hydrodynamics in order to illustrate in detail the numerical methods commonly used in fluid dynamics, specifically th…
Is the flip-flop behaviour of accretion shock cones on to black holes an effect of coordinates?
A. Cruz-Osorio, F. D. Lora-Clavijo, F. S. Guzman
We study numerically the relativistic Bondi-Hoyle accretion of an ideal gas onto a Kerr fixed background space-time on the equatorial plane with s-lab symmetry. We use both Kerr-Sc…
Behavior of Phantom Scalar Fields near Black Holes
F. D. Lora-Clavijo, J. A. Gonzalez, F. S. Guzman
We present the accretion of a phantom scalar field into a black hole for various scalar field potentials in the full non-linear regime. Our results are based on the use of numerica…
Charged Annular Disks and Reissner-Nordström Type Black Holes from Extremal Dust
F. D. Lora-Clavijo, P. A. Ospina-Henao, J. F. Pedraza
We present the first analytical superposition of a charged black hole with an annular disk of extremal dust. In order to obtain the solutions, we first solve the Einstein-Maxwell f…
