Stationary cosmic string loops in the universe
Abstract:We describe the electromagnetic and gravitational radiation from cosmic string loops with an electromagnetic current and their evolution to the stationary (vorton) state. The upper bounds on gravitational and electromagnetic radiation are found and the oscillation damping time of closed chiral strings is estimated. The analytical dependence of energy of the string with time is obtained in the case of radially oscillating ring. We found the minimal length of string that oscillates up to the present time and discuss some astrophysical applications of vortons.
