Abstract / short description:
Summary: The majority of stars reside in binary star systems. During their formation a sufficiently close binary star system is still surrounded by a circumbinary disc from which there is still material being accreted onto the binary. The orbital motion of the binary transfers angular momentum to the disc and a central inner cavity forms. These cavities have been directly detected in some special systems and the high spatial resolution capabilities of ALMA will allow to investigate more of these sources in even higher detail. A very active recent research topic is the formation and evolution of the circumbinary planets in these discs as observed by the Kepler-mission. Clearly, the structure and dynamics of the circumbinary disc is strongly influenced by the properties of the binary star. In this project we plan to perform new two- and three-dimensional hydrodynamical simulations to elaborate the detailed structure of the disc. In particular the inner regions close to the stars are in the focus of this research. Given the disc physics we will perform evolutionary simulations of embedded planets and compare their final configuration with the results of the Kepler mission, in order to understand their formation process.
