Scattering of a Long Cosmic String by a Rotating Black Hole
Martin Snajdr, Valeri Frolov, Jean-Pierre DeVilliers
The scattering of a straight, infinitely long string by a rotating black hole is considered. We assume that a string is moving with velocity v and that initially the string is para…
Three-Dimensional Hydrodynamic Simulations of Accretion Tori in Kerr Spacetimes
Jean-Pierre De Villiers, John F. Hawley
This paper presents results of three-dimensional simulations of global hydrodynamic instabilities in black hole tori, extending earlier work by Hawley to Kerr spacetimes. This stud…
Gravitational Scattering of Cosmic Strings by Non-Rotating Black Holes
Jean-Pierre De Villiers, Valeri Frolov
This paper discusses the gravitational scattering of a straight, infinitely long test cosmic string by a black hole. We present numerical results that probe the two-dimensional par…
Scattering of Straight Cosmic Strings by Black Holes: Weak Field Approximation
Jean-Pierre De Villiers, Valeri Frolov
The scattering of a straight, infinitely long string moving with velocity by a black hole is considered. We analyze the weak-field case, where the impact parameter ()…
Gravitational Capture of Cosmic Strings by a Black Hole
Jean-Pierre De Villiers, Valeri P. Frolov
The gravitational interaction of an infinitely long cosmic string with a Schwarzschild black hole is studied. We consider a straight string that is initially at a great distance an…
Rigidly Rotating Strings in Stationary Spacetimes
V. Frolov, S. Hendy, J. P. De Villiers
In this paper we study the motion of a rigidly rotating Nambu-Goto test string in a stationary axisymmetric background spacetime. As special examples we consider the rigid rotation…
