New limits to moist greenhouse worlds. Is Tohul in danger?
#1
So, I found this paper: The Effect of High Nitrogen Pressures On The Habitable Zone and an Appraisal of Greenhouse States

This seems very applicable to Tohul, a moist greenhouse with a thick nitrogen atmosphere. 

I haven't read through it completely yet, but according to the paper, higher nitrogen pressures extend the inner edge of the habitable zone inwards. What's really interesting, and problematic for Tohul, is that moist greenhouses may only be possible around A-type stars, which probably wouldn't last long enough for a sophont race to arise. 

If this turns out to be the case, then Tohul may need to be drastically altered.
