Abstract
Discoveries of planets in binary star systems showed that planetary companions are not restricted to single stars and led to a growing interest in understanding planetary formation processes in general. In binary star systems, the proto-planetary disk is truncated due to the secondary star which has strong influence on the formation of planets.
Despite numerous scientific studies thereto, we are still faced with many open questions regarding where and how a planet can grow in such environments as there are many parameters that affect the outcome of hydrodynamical simulations.
In contrast thereto, terrestrial planet formation using gravitational N-body simulations can be easily performed. In either case, the architecture of a binary star -- giant planet system influences the formation and evolution of additional planets. Furthermore, resonances play an important role for accretion processes and for the final set up of a planetary system.
