Carbon dioxide at the outer edge of the habitable zone

Atmospheric constraints for the CO2 partial pressure on terrestrial planets near the outer edge of the habitable zone

Various effects of stellar insolation, etc.

One potentially interesting consequence:
As has been shown above (Fig. 3), for planets orbiting within the HZ of K-G-F stars there is a region of liquid surface CO2 combined with surface temperatures above 273 K, i.e. liquid surface H2O. This means that it is possible to form H2O-CO2 oceans.
