Dynamics and habitability in circumstellar planetary systems of known binary stars

We present a survey on exoplanetary systems of binary stars with stellar separations less than 100 au. For a sample of 11 binaries that harbour detected circumstellar giant planets, we investigate the frequency of systems with secular resonances (SR) affecting the habitable zone (HZ). SR are connected to dynamically unstable or chaotic regions by enforcing highly eccentric motion. We apply a semi-...
