N2 - 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 set-ups 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.
