Query: Dilatonic, Chiral Cosmic Strings   In this work, we deal with the chiral string model for which the world-sheet
current is null in the framework of a scalar-tensor gravity. Our main goal is
to analyse the impact of such a current on the gravitational macroscopic
effects. For the purpose of this analysis, we first study the gravitational
properties of the spacetime generated by this string in the presence of a
dilaton field. Then, we carry out an investigation of the mechanism of
formation and evolution of wakes in this framework, showing the explicit
contribution of the chirality to this effect.
