Abstrakt

We present a study on S-type planets in binary star systems with separations a < 100 AU. For systems with at least one detected giant planet we determine the location of (linear) secular resonances with that planet by means of a semi-analytical method. We demonstrate that under some conditions, e.g. when the secondary star is at about 20 AU, the habitable zone can be perturbed or completely destabilized in these systems.
