  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.
