Habitability of Earth-type Planets and Moons in the Kepler-16 System    [PDF]

Billy Quarles, Zdzislaw E. Musielak, Manfred Cuntz
We demonstrate that habitable Earth-type planets and moons can exist in the Kepler-16 system by investigating their orbital stability in the standard and extended habitable zone (HZ). We find that Earth-type planets in S-type orbits are possible within the standard HZ in direct vicinity of Kepler-16b, thus constituting habitable exomoons. However, Earth-mass planets cannot exist in P-type orbits around the two stellar components within the standard HZ. Yet, P-type Earth-mass planets can exist superior to the giant planet in the extended HZ pertaining to considerably enhanced back-warming in the planetary atmosphere if facilitated. We briefly discuss the potential detectability of such habitable Earth-type moons and planets positioned in S-type and P-type orbits, respectively.
