Fitting Formulas for Determining the Existence of S-type and P-type   Habitable Zones in Binary Systems: First Results
  We present initial work about attaining fitting formulas for the quick determination of the existence of S-type and P-type habitable zones in binary systems. Following previous work, we calculate the limits of the climatological habitable zone in binary systems (which sensitively depend on the system parameters) based on a joint constraint encompassing planetary orbital stability and a habitable region for a possible system planet. We also consider updated results on planetary climate models previously obtained by Kopparapu and collaborators. Fitting equations based on our work are presented for selected cases.
