Epicyclic oscillations in the Hartle-Thorne external geometry
Gabriela Urbancová, Martin Urbanec, Gabriel Török +3
The external Hartle-Thorne geometry, which describes the space-time outside a slowly-rotating compact star, is characterized by the gravitational mass , angular momentum and…
Tidal disruptions by rotating black holes: relativistic hydrodynamics with Newtonian codes
Emilio Tejeda, Emanuel Gafton, Stephan Rosswog +1
We propose an approximate approach for studying the relativistic regime of stellar tidal disruptions by rotating massive black holes. It combines an exact relativistic description…
An analytic toy model for relativistic accretion in Kerr spacetime
Emilio Tejeda, Paul A. Taylor, John C. Miller
We present a relativistic model for the stationary axisymmetric accretion flow of a rotating cloud of non-interacting particles falling onto a Kerr black hole. Based on a ballistic…
Role of electric charge in shaping equilibrium configurations of fluid tori encircling black holes
Jiří Kovář, Petr Slaný, Zdeněk Stuchlík +3
Astrophysical fluids may acquire non-zero electrical charge because of strong irradiation or charge separation in a magnetic field. In this case, electromagnetic and gravitational…
Analytic solutions to the accretion of a rotating finite cloud towards a central object - II. Schwarzschild spacetime
Emilio Tejeda, Sergio Mendoza, John C. Miller
We construct a general relativistic model for the accretion flow of a rotating finite cloud of non-interacting particles infalling onto a Schwarzschild black hole. The streamlines…
Kinetic description of quasi-stationary axisymmetric collisionless accretion disk plasmas with arbitrary magnetic field configurations
Claudio Cremaschini, John C. Miller, Massimo Tessarotto
A kinetic treatment is developed for collisionless magnetized plasmas occurring in high-temperature, low-density astrophysical accretion disks, such as are thought to be present in…
