Zusammenfassung

The main objective of this project is to consider models of mixed objects, which consist not only of ordinary matter but of a scalar field as well, and to study their properties. In doing so, it is assumed using scalar fields which could both drive the current accelerated expansion of the Universe as well as create boson stars. In the first case, it is possible to consider configurations consisting of phantom/ghost scalar fields that may lead to the presence of nontrivial (wormhole) topology. Such star-plus-wormhole systems will have new physical properties that distinguish them from ...
