Cosmic strings and Einstein-Rosen soliton waves Garriga Torres, Jaume Verdaguer Oms, Enric, 1950- Relativitat general (Física) Matèria interstel·lar Solitons Cordes còsmiques Solucions numèriques General relativity (Physics) Interstellar matter Solitons Cosmic strings Numerical solutions We consider all generalized soliton solutions of the Einstein-Rosen form in the cylindrical context. They are Petrov type-I solutions which describe solitonlike waves interacting with a line source placed on the symmetry axis. Some of the solutions develop a curvature singularity on the axis which is typical of massive line sources, whereas others just have the conical singularity revealing the presence of a static cosmic string. The analysis is based on the asymptotic behavior of the Riemann and metric tensors, the deficit angle, and a C-velocity associated to Thornes C-energy. The C-energy is found to be radiated along the null directions. 2010-05-06T09:58:17Z 2010-05-06T09:58:17Z 1987 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 0556-2821 https://hdl.handle.net/2445/12405 79603 eng Reproducció digital del document publicat en format paper, proporcionada per PROLA i http://dx.doi.org/10.1103/PhysRevD.36.2250 Physical Review D, 1987, vol. 36, núm. 8, p. 2250-2258 http://dx.doi.org/10.1103/PhysRevD.36.2250 (c) The American Physical Society, 1987 info:eu-repo/semantics/openAccess 9 p. application/pdf The American Physical Society Articles publicats en revistes (Física de la Matèria Condensada)
