Dynamics of Relativistic Flows
(arXiv, 200405)Dynamics of relativistic outflows along the rotation axis of a Kerr black hole is investigated using a simple model that takes into account the relativistic tidal force of the central source as well as the Lorentz force ... 
Relativistic motion of spinning particles in a gravitational field
(arXiv, 200505)The relative motion of a classical relativistic spinning test particle is studied with respect to a nearby free test particle in the gravitational field of a rotating source. The effects of the spincurvature coupling force ... 
Tidal acceleration of ultrarelativistic particles
(EDP Sciences, 200505)We investigate the motion of free relativistic particles relative to the ambient medium around a gravitationally collapsed system. If the relative speed exceeds a critical value given by c/√2, the gravitational tidal ... 
Tidal dynamics in Kerr spacetime
(Institute of Physics, 200605)The motion of free nearby test particles relative to a stable equatorial circular geodesic orbit about a Kerr source is investigated. It is shown that the nonlinear generalized Jacobi equation can be transformed in this ... 
Ultrarelativistic motion: inertial and tidal effects in Fermi coordinates
(Institute of Physics, 200412)Fermi coordinates are the natural generalization of inertial Cartesian coordinates to accelerated systems and gravitational fields. We study themotion of ultrarelativistic particles and light rays in Fermi coordinates ...
