Atmospheric dynamics of temperate sub-Neptunes. Part I: dry dynamics
Hamish Innes, Raymond T. Pierrehumbert
Sub-Neptunes (planets with radii between 2 and 4 R) are abundant around M-dwarf stars, yet the atmospheric dynamics of these planets is relatively unexplored. In this pa…
Convection modeling of pure-steam atmospheres
Xianyu Tan, Maxence Lefevre, Raymond Pierrehumbert
Condensable species are crucial in shaping planetary climate. A wide range of planetary climate systems involve understanding non-dilute condensable substances and their influence…
Inferring Shallow Surfaces on sub-Neptune Exoplanets with JWST
Shang-Min Tsai, Hamish Innes, Tim Lichtenberg +4
Planets smaller than Neptune and larger than Earth make up the majority of the discovered exoplanets. Those with H-rich atmospheres are prime targets for atmospheric characteri…
A multispecies pseudoadiabat for simulating condensable-rich exoplanet atmospheres
R. J. Graham, Tim Lichtenberg, Ryan Boukrouche +1
Central stages in the evolution of rocky, potentially habitable planets may play out under atmospheric conditions with a large inventory of non-dilute condensable components. Varia…
Beyond runaway: initiation of the post-runaway greenhouse state on rocky exoplanets
Ryan Boukrouche, Tim Lichtenberg, Raymond T. Pierrehumbert
The runaway greenhouse represents the ultimate climate catastrophe for rocky, Earth-like worlds: when the incoming stellar flux cannot be balanced by radiation to space, the oceans…
Simulating gas giant exoplanet atmospheres with Exo-FMS: Comparing semi-grey, picket fence and correlated-k radiative-transfer schemes
Elspeth K. H. Lee, Vivien Parmentier, Mark Hammond +5
Radiative-transfer (RT) is a fundamental part of modelling exoplanet atmospheres with general circulation models (GCMs). An accurate RT scheme is required for estimates of the atmo…
3D convection-resolving model of temperate, tidally-locked exoplanets
Maxence Lefèvre, Martin Turbet, Raymond Pierrehumbert
A large fraction of known terrestrial-size exoplanets located in the Habitable Zone of M-dwarfs are expected to be tidally-locked. Numerous efforts have been conducted to study the…
Evidence for disequilibrium chemistry from vertical mixing in hot Jupiter atmospheres. A comprehensive survey of transiting close-in gas giant exoplanets with warm-Spitzer/IRAC
C. Baxter, J-M. Désert, S-M. Tsai +10
[Abridged] Aims. We present a large atmospheric study of 49 gas giant exoplanets using infrared transmission photometry with Spitzer/IRAC at 3.6 and 4.5um. Methods. We uniformly an…
Vertically resolved magma ocean-protoatmosphere evolution: H, HO, CO, CH, CO, O, and N as primary absorbers
Tim Lichtenberg, Dan J. Bower, Mark Hammond +4
The earliest atmospheres of rocky planets originate from extensive volatile release during magma ocean epochs that occur during assembly of the planet. These establish the initial…
