Coupled Photochemical-Climate Modeling of Plausible Tenuous Outgassed Atmospheres on the TRAPPIST-1 Planets

Andrew Lincowski, David Brain, David Crisp, Megan Gialluca, Parker Hinton, Trent Thomas, Victoria Meadows

Tenuous atmospheres on the TRAPPIST-1 planets can persist if water and CO2 outgassing balances high escape rates.

✓ Portable graph bundle live · download bundle · merged state

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

we show that tenuous atmospheres on the TRAPPIST-1 planets are likely possible, supported by constant plausible rates of water and/or CO2 outgassing against assumed high escape rates (up to ~10^30 s^{-1}).

C2weakest assumption

The assumption that escape rates reach up to 10^30 s^{-1} and that outgassing rates can be sustained at levels that exactly balance them over long timescales.

C3one line summary

Tenuous outgassed H2O and CO2 atmospheres on TRAPPIST-1 planets are possible at 10^-4 to 1 bar and match JWST transmission data, with potential habitability on d and e.
