Silane-Methane Competition in Sub-Neptune Atmospheres as a Diagnostic of Metallicity and Magma Oceans
Kaustubh Hakim, Dan J. Bower, Fabian L. Seidler +1
The James Webb Space Telescope is characterising the atmospheres of sub-Neptunes. The presence of magma oceans on sub-Neptunes is expected to strongly alter the chemistry of their…

Diversity of low-mass planet atmospheres in the C-H-O-N-S-Cl system with interior dissolution, nonideality, and condensation: Application to TRAPPIST-1e and sub-Neptunes
Dan J. Bower, Maggie A. Thompson, Kaustubh Hakim +2
A quantitative understanding of the nature and composition of low-mass rocky (exo)planet atmospheres during their evolution is needed to interpret observations. The magma ocean sta…

The effect of a biosphere on the habitable timespan of stagnant-lid planets and implications for the atmospheric spectrum
Dennis Höning, Ludmila Carone, Philipp Baumeister +6
Temperature-dependent biological productivity controls silicate weathering and thereby extends the potential habitable timespan of Earth. Models and theoretical considerations indi…
