Modeling Volcanic Plume Heights Across Exoplanet Atmospheres: Insights from TRAPPIST-1

Prabal Saxena, Thomas Fauchez

A 1D model adapted for exoplanets predicts that volcanic plumes frequently reach low-pressure levels suitable for detection in transmission observations.

Claims

C1strongest claim

These results provide a physically grounded framework for predicting whether and how volcanic emissions might be detected on rocky exoplanets, including-but not limited to-those experiencing strong tidal heating.

C2weakest assumption

The 1D plume model assumptions (vent thermodynamics, buoyant entrainment, and vertically varying static stability) originally developed for Venus and Mars transfer without major revision to the diverse exoplanet background states explored.

C3one line summary

A Python port of a classic volcanic plume model is applied to exoplanet conditions, identifying parameter regions where plumes reach low-pressure altitudes and become potentially detectable.
