These figures and videos show the habitable zones around the circumbinary planet-hosting systems of Kepler 16, Kepler 34, Kepler 35, Kepler 38, Kepler 47, Kepler 64, and Kepler 453. The related calculations of the boundaries of the habitable zone can be found in Haghighipour & Kaltenegger (2013) and Kaltenegger & Haghighipour (2013). Each system is displayed for different constellations of the binary system. The video shows the habitable zone for one orbit of the binary. The dashed line corresponds to the inner boundary of stable planetary orbits and has been calculated using the stability criterion given by Holman & Wiegert (1999).

The Kepler 453 system is described in Welsh et. al (2015). The orbits of stars and planets in those figures are N-body integrations of the observed data.

If you want to create similar figures for different systems try out the interactive website for habitable zones in multiple star systems. Similar figures of multiple star systems can be found at the website for habitable zones in multiple star stars.

You are welcome to use any of the figures and movies on this website in your papers, presentations and for teaching. In that case, please include the following in the text of your paper/presentation: Figure/Movie courtesy of Tobias Müller (Institute for Astronomy & Astrophysics, University of Tübingen) obtained from P-type HZ calculator (http://astro.twam.info/hz-ptype, Kaltenegger & Haghighipour (2013), and Haghighipour & Kaltenegger (2013)).

Due to the huge number of movies on this website, it may take a while to load them all. Please be patient.
