A broad exploration of climate and observability of close-in rocky exoplanets: applications to Ross 128 b
Mathilde Houelle, Emeline Bolmont, Christophe Lovis +4
VLT/RISTRETTO, ELT/ANDES and ELT/PCS will soon enable atmospheric characterization of non-transiting, small rocky exoplanets orbiting closer than the inner edge of the Habitable Zo…
Atmospheric asymmetries in WASP-121 b revealed by rotational transits detected with JWST
Cyril Gapp, Aurélien Falco, Thomas M. Evans-Soma +6
Close-in exoplanets are tidally locked to their host star and thus exhibit extreme atmospheric temperature gradients. It has been theorized that the fraction of star light absorbed…
Detection of stratospheric HCN and tropospheric CO in Uranus and the implication for their sources
T. Cavalié, R. Moreno, C. Lefour +16
Uranus belongs to the category of ice giants that are common in our Galaxy. However, Uranus is one of the least explored and understood planets in our Solar System. This work aims…
Next-generation Exo-REM atmospheric models: application to VHS 1256 b to emulate patchy clouds
Alice Radcliffe, Benjamin Charnay, Anne-Marie Lagrange +7
Condensate clouds are a defining feature of brown dwarf and exoplanet atmospheres, producing a broad range of colours on the CMD and giving rise to spectral features such as the di…
Latitudinal variations in Neptune's temperature profile observed with ALMA
Óscar Carrión-González, Raphael Moreno, Emmanuel Lellouch +5
Despite the low solar irradiation it receives, Neptune shows a very active atmosphere with some of the most intense dynamics observed in Solar System atmospheres. Characterizing th…
Coupled atmospHere Interior modeL Intercomparison (CHILI) Protocol Version 1.0: A CUISINES Intercomparison Project of Magma Ocean Models
Tim Lichtenberg, Laura Schaefer, Joshua Krissansen-Totton +23
Spectroscopic characterization of rocky exoplanets with the James Webb Space Telescope has brought the origin and evolution of their atmospheres into the focus of exoplanet science…
First JWST thermal phase curves of temperate terrestrial exoplanets reveal no thick atmosphere around TRAPPIST-1 b and c
Michaël Gillon, Elsa Ducrot, Taylor J. Bell +30
We report JWST/MIRI 15 m phase curves of TRAPPIST-1 b and c, revealing thermal emission consistent with their irradiation levels, assuming no efficient heat redistribution. We f…
Constraints on the possible atmospheres on TRAPPIST-1 b: insights from 3D climate modeling
Alice Maurel, Martin Turbet, Elsa Ducrot +13
JWST observations of the secondary eclipse of TRAPPIST-1 b at 12.8 and 15 microns revealed a very bright dayside. These measurements are consistent with an absence of atmosphere. P…
Storms and convection on Uranus and Neptune: impact of methane abundance revealed by a 3D cloud-resolving model
Noé Clément, Jérémy Leconte, Aymeric Spiga +8
Uranus and Neptune have atmospheres dominated by molecular hydrogen and helium. In the upper troposphere, methane is the third main molecule and condenses, yielding a vertical grad…
Radiative-convective models of the atmospheres of Uranus and Neptune: heating sources and seasonal effects
G. Milcareck, S. Guerlet, F. Montmessin +10
The observations made during the Voyager 2 flyby have shown that the stratosphere of Uranus and Neptune are warmer than expected by previous models. In addition, no seasonal variab…
Signature of the atmospheric asymmetries of hot and ultra-hot Jupiters in lightcurves
Aurélien Falco, Jérémy Leconte, Alexandre Mechineau +1
With the new generation of space telescopes such as the James Webb Space Telescope (JWST), it is possible to better characterize the atmospheres of exoplanets. The atmospheres of H…
Modeling Atmospheric Lines By the Exoplanet Community (MALBEC) version 1.0: A CUISINES radiative transfer intercomparison project
Geronimo L. Villanueva, Thomas J. Fauchez, Vincent Kofman +15
Radiative transfer (RT) models are critical in the interpretation of exoplanetary spectra, in simulating exoplanet climates and when designing the specifications of future flagship…
The radiative and dynamical impact of clouds in the atmosphere of the hot Jupiter WASP-43 b
Lucas Teinturier, Benjamin Charnay, Aymeric Spiga +6
Hot Jupiters exhibit large day-night temperature contrasts. Their cooler nightsides are thought to host clouds. However, the exact nature of these clouds, their spatial distributio…
Nightside clouds and disequilibrium chemistry on the hot Jupiter WASP-43b
Taylor J. Bell, Nicolas Crouzet, Patricio E. Cubillos +80
Hot Jupiters are among the best-studied exoplanets, but it is still poorly understood how their chemical composition and cloud properties vary with longitude. Theoretical models pr…
ARES VI: Viability of one-dimensional retrieval models for transmission spectroscopy characterization of exo-atmospheres in the era of JWST and Ariel
Adam Yassin Jaziri, William Pluriel, Andrea Bocchieri +10
Observed exoplanet transit spectra are usually retrieved using 1D models to determine atmospheric composition while planetary atmospheres are 3D. With the JWST and future space tel…
Doppler wind measurements in Neptune's stratosphere with ALMA
Óscar Carrión-González, Raphael Moreno, Emmanuel Lellouch +6
Neptune's tropospheric winds are among the most intense in the Solar System, but the dynamical mechanisms that produce them remain uncertain. Measuring wind speeds at different pre…
Early Release Science of the Exoplanet WASP-39b with JWST NIRSpec G395H
Lili Alderson, Hannah R. Wakeford, Munazza K. Alam +89
Measuring the abundances of carbon and oxygen in exoplanet atmospheres is considered a crucial avenue for unlocking the formation and evolution of exoplanetary systems. Access to a…
