A 3D picture of moist-convection inhibition in hydrogen-rich atmospheres: Implications for K2-18 b
Jérémy Leconte, Aymeric Spiga, Noé Clément +9
While small, Neptune-like planets are among the most abundant exoplanets, our understanding of their atmospheric structure and dynamics remains sparse. In particular, many unknowns…
The Impact of Turbulent Vertical Mixing in the Venus Clouds on Chemical Tracers
Maxence Lefèvre, Emmanuel Marcq, Franck Lefèvre
Venus clouds host a convective layer between roughly 50 and 60 km that mixes heat, momentum, and chemical species. Observations and numerical modelling have helped to understand th…
Venus boundary layer dynamics: eolian transport and convective vortex
Maxence Lefèvre
Few spacecraft have studied the dynamics of Venus' deep atmosphere, which is needed to understand the interactions between the surface and atmosphere. Recent global simulations sug…
Cloud-convection feedback in brown dwarfs atmosphere
Maxence Lefèvre, Xianyu Tan, Elspeth K. H. Lee +1
Numerous observational evidence has suggested the presence of active meteorology in the atmospheres of brown dwarfs. A near-infrared brightness variability has been observed. Cloud…
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…
Characterising atmospheric gravity waves on the nightside lower clouds of Venus: a systematic analysis
J. E. Silva, P. Machado, J. Peralta +3
We present the detection and characterisation of mesoscale waves on the lower clouds of Venus using images from the Visible Infrared Thermal Imaging Spectrometer onboard the Europe…
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…
Ariel: Enabling planetary science across light-years
Giovanna Tinetti, Paul Eccleston, Carole Haswell +313
Ariel, the Atmospheric Remote-sensing Infrared Exoplanet Large-survey, was adopted as the fourth medium-class mission in ESA's Cosmic Vision programme to be launched in 2029. Durin…
TRAPPIST Habitable Atmosphere Intercomparison (THAI) workshop report
Thomas J. Fauchez, Martin Turbet, Denis E. Sergeev +31
The era of atmospheric characterization of terrestrial exoplanets is just around the corner. Modeling prior to observations is crucial in order to predict the observational challen…
Mesoscale modeling of Venus' bow-shape waves
Maxence Lefèvre, Aymeric Spiga, Sébastien Lebonnois
The Akatsuki instrument LIR measured an unprecedented wave feature at the top of Venusian cloud layer. Stationary bow-shape waves of thousands of kilometers large lasting several E…
VUV-absorption cross section of carbon dioxide from 150 to 800 K and applications to warm exoplanetary atmospheres
Olivia Venot, Yves Bénilan, Nicolas Fray +9
Most exoplanets detected so far have atmospheric T significantly higher than 300K. Often close to their star, they receive an intense UV photons flux that triggers important photod…
