Abstract
We derive fitting formulae for the quick determination of the existence of
S-type and P-type habitable zones in binary systems. Based on previous work, we
consider 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. Additionally, we employ updated results on planetary climate
models obtained by Kopparapu and collaborators. Our results are applied to four
P-type systems (Kepler-34, Kepler-35, Kepler-413, and Kepler-1647) and two
S-type systems (TrES-2 and KOI-1257). Our method allows to gauge the existence
of climatological habitable zones for these systems in a straightforward manner
with detailed consideration of the observational uncertainties. Further
applications may include studies of other existing systems as well as systems
to be identified through future observational campaigns.
