Motion of test particles in the cosmic string space-time with dark string — Betti Hartmann¹ and •Valeria Kagramanova² — ¹Jacobs University Bremen — ²Carl von Ossietzky Universität Oldenburg

We study geodesics in the space-time of an Abelian-Higgs string coupled to a dark string. The dark strings are a prediction of dark matter models that could explain the excess of electronic production in the galaxy. The Abelian-Higgs string and the dark string are coupled through the U(1) fields. We investigate the influence of the parameters of the model on the properties of the test particles motion and on the classification of orbits.
