Are planets like the "To'ul'hian Worlds" from Orion's Arm plausible?

+0
−0

The Orion's Arm Universe Project includes a description of what they call "To'ul'hian Worlds", planets that are (in the simplest of terms) a cross between Earth and Venus.

I'm working on designing a similar planet for an unconnected story, and this OAUP page is the closest thing to a reference for my setting that I've found so far.

@galactic_analyzer suggests that the OAUP world's COâ‚‚ atmosphere is problematic, and I'd prefer an Earth-like nitrox atmosphere anyway, so for this question let's make that replacement.

Could a planet like this exist in real life? If not, what specifically causes problems with the concept?

The key points are:

  • surface pressure of 10 to 100 bars
  • surface temperature of 100 to 200 degrees Celsius
    • Note: at 10 bar, maximum temperature is 180°C; at 200°C, minimum pressure is 16 bar
  • liquid water at the planet's surface
  • an active carbon cycle
  • develops oxygen-producing airborne life
  • atmosphere includes thermosphere and ozone layer
  • atmosphere consists primarily of carbon dioxide nitrox
