Wiggly Strings in Linearized Brans-Dicke Gravity
Andres Arazi, Claudio Simeone
Abstract
The metric around a wiggly cosmic string is calculated in the linear approximation of Brans-Dicke theory of gravitation. The equations of motion for relativistic and non-relativistic particles in this metric are obtained. Light propagation is also studied and it is shown that photon trajectories can be bounded.
