The habitable zone of Kepler-16: impact of binarity and climate models

We continue to investigate the binary system Kepler-16, consisting of a K-type main-sequence star, a red dwarf, and a circumbinary Saturnianplanet. As part of our study, we describe the system's habitable zone based on different climate models. We also report on stability investigations for possible Earth-mass Trojanswhile expanding a previous study by B. L. Quarles and collaborators given in 2012. For the climate modelswe carefully consider the relevance of the system's parameters. Furthermore, we pursue new stability simulations for the Earth-massobjects starting along the orbit of Kepler-16b. The eccentricity distribution as obtained prefers values close to circular, whereas the inclination distribution remains flat. The stable solutions are distributed near the co-orbital Lagrangian points, thus enhancing the plausibility that Earth-mass Trojansmight be able to exist in the Kepler-16(AB) system.
