Using this website, you can calculate the habitable zones of single, binary and multiple star systems (for single stars use the multiple star option with only one star. You can then compare the results with the HZ Gallery and the HZ Calculator). The methodology for calculating the HZ is described in Müller & Haghighipour (2014). The HZ can be calculated using the models by Kopparapu et. al (2014) (assuming Mplanet = 1 MEarth), Kopparapu et. al (2013), Selsis et. al (2007), or Kasting et. al (1993). The stability radii in the binary cases are calculated using the formulae given by Holman & Wiegert (1999).

Movies of time-dependent habitable zones can be found at http://astro.twam.info/hz-ptype and http://astro.twam.info/hz-multi.
