Locations of the stable and habitable zones in our system, as discussed in Sect. 5. The distances are the initial orbital distance of the planet measured from the centre of mass of the two stars. The purple zone is the region in which stable planetary orbits are not possible. Planets in the red regions are not habitable because they are either too hot or too cold for the formation of liquid water. The blue, green, and yellow regions show the locations of the permanently habitable zones, the extended habitable zones, and the average habitable zone, respectively. The solid and dotted vertical lines show the inner and outer limits of the classical habitable zone calculated using the method of Kopparapu et al. (2014) for single stars, assuming a central star bolometric luminosity equal to the sums of the bolometric luminosities of the two stars in our binary system.
