Geodesics in spacetimes containing cosmic strings
Abstract
A systematic study of geodesics in spacetimes containing cosmic strings is presented. Different models of spacetime of a single string as well as models of asymptotically conical spacetimes describing isolated matter systems pierced by cosmic strings are studied. Geodesics in the flat conical, conical Schwarzschild and LenseThirring spacetimes are described in detail. The problem of twobody motion in the presence of a cosmic string is also discussed. Many new kinematical effects arising from the conical structure of spacetime are found.
