We consider a local cosmic string described by the Abelian-Higgs model in the framework of scalar-tensor gravities. We nd the metric of the cosmic string in the weakeld approximation. The propagation of particles and light is analysed in this background. This analysis shows that the (unperturbed) cosmic string in scalar-tensor theory presents some analogous… (More)
