Latitudinal chemical and cloud variations in the atmosphere of a brown dwarf
Benjamin Charnay, Sam de Regt, Matthieu Ravet +8
Brown dwarfs are massive analogues of extrasolar giant planets. Compared to exoplanets whose observations are generally limited by the presence of their bright host star, brown dwa…
Phase-dependent chemistry of WASP-43 b revealed with a suite of one-, two-, and three-dimensional models
Robin Baeyens, Julianne I. Moses, Jasmina Blecic +17
Our goal is to investigate the chemistry of the hot Jupiter WASP-43 b in detail using theoretical models, considering the constraints of the James Webb Space Telescope MIRI phase c…
Clouds as the driver of variability and colour changes in brown dwarf atmospheres
Lucas Teinturier, Benjamin Charnay, Aymeric Spiga +1
Brown dwarfs are massive, giant exoplanet analogues subject to variability and colour changes, known as the L/T transition, fundamental for their thermal evolution. The drivers of…
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…
Warm Jupiters around M-dwarfs are great opportunities for extensive chemical, cloud and haze characterisation with JWST
Lucas Teinturier, Elsa Ducrot, Benjamin Charnay
The population of short-period giant exoplanets around M-dwarf stars is slowly rising. These planets present an extraordinary opportunity for atmospheric characterisation and defy…
Simultaneous retrieval of orbital phase resolved JWST/MIRI emission spectra of the hot Jupiter WASP-43b: evidence of water, ammonia and carbon monoxide
Jingxuan Yang, Mark Hammond, Anjali A. A. Piette +14
Spectroscopic phase curves of hot Jupiters measure their emission spectra at multiple orbital phases, thus enabling detailed characterisation of their atmospheres. Precise constrai…
Two-Dimensional Eclipse Mapping of the Hot Jupiter WASP-43b with JWST MIRI/LRS
Mark Hammond, Taylor J. Bell, Ryan C. Challener +21
We present eclipse maps of the two-dimensional thermal emission from the dayside of the hot Jupiter WASP-43b, derived from an observation of a phase curve with the JWST MIRI/LRS in…
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…
ATMOSPHERIX: II- Characterising exoplanet atmospheres through transmission spectroscopy with SPIRou
F. Debras, B. Klein, J. -F. Donati +26
In a companion paper, we introduced a publicly-available pipeline to characterise exoplanet atmospheres through high-resolution spectroscopy. In this paper, we use this pipeline to…
ATMOSPHERIX: I- An open source high resolution transmission spectroscopy pipeline for exoplanets atmospheres with SPIRou
B. Klein, F. Debras, J. -F. Donati +28
Atmospheric characterisation of exoplanets from the ground is an actively growing field of research. In this context we have created the ATMOSPHERIX consortium: a research project…
Mapping the Surface of Partially Cloudy Exoplanets is Hard
Lucas Teinturier, Nicholas Vieira, Elisa Jacquet +4
Reflected light photometry of terrestrial exoplanets could reveal the presence of oceans and continents, hence placing direct constraints on the current and long-term habitability…
