- Abstract
Wide binary star systems with circumstellar exoplanets are generally believed to be conducive to habitable planets. We demonstrate that in the presence of a giant planet secular perturbations can affect the habitable zone for a wide range of system parameters. Such perturbations lead to enhanced eccentricities of terrestrial planets and are detrimental to sustain habitable conditions on the planet. We develop a diagnostic tool based on analytical models that allows an easyidentification of observed binary systems lacking habitable conditions from a dynamical point of view.
