These figures and videos illustrate the habitable zones around multiple star systems using the examples of KIC 4150611, KIC 4150611 Limit1, KIC 4150611 Limit2, KID 5653126, KID 5653126 Case 1, KID 5653126 Case 2, Figure Eight Orbit, Figure Eight Scaled, Equilateral Triangle Circular and Equilateral Triangle Eccentric. For each system a video and a few snapshots of the habitable zone are provided. For some of the system you can switch between different videos where, for instance, stellar orbits or stability limits are also included.

The calculations of the HZ in multiple star systems (including the examples above) have been fully explained in Müller & Haghighipour (2014). If you would like to create similar figures for different systems try the interactive website for habitable zones in multiple star systems. Similar figures for circumbinary habitable zones can be found at our website for habitable zones in P-type binary systems.

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 cite Müller & Haghighipour (2014).

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