On The Enlargement Of Habitable Zones Around Binary Stars in Hostile Environments


Circumbinary star system

We investigate the hypothesis that the size of the habitable zone around hardened binaries in dense star-forming regions increases. Our results indicate that this hypothesis is essentially incorrect.

Although certain binary star configurations permit extended habitable zones, such setups typically require all orbits in a system to be near circular. In all other cases planets can only remain habitable if they display an extraordinarily high climate inertia.
