From spinning to non-spinning cosmic string spacetimes

Abstract

We analyse the properties of a fluid generating a spinning cosmic string spacetime with flat limiting cases corresponding to a constant angular momentum in the infinite past and static configuration in the infinite future. The spontaneous loss of angular momentum of a spinning cosmic string due to particle emission is discussed. The rate of particle production between the spinning and non-spinning cosmic string spacetimes is calculated.Comment: 11 pages, 1 figure, LaTeX To appear in Class. Quantum Gra
