Abstract

Wagner et al. (2016) reported the discovery of a Jovian planet within a triple-star system by using direct imaging. In their paper they suspect the planet might be on an unstable orbit. Due to the discovery by direct imaging the orbital parameters of the system (distances and eccentricities) possess large uncertainties. Therefore in our work we tested different dynamical configurations to determine the stable regions in the system HD 131399 by varying the distances and the eccentricities of the stellar and the planetary components. Using different numerical methods we could show that stable regions remain for almost all possible orbital parameters. Additionally we also investigated the possible habitability of the system HD 131399.
