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…
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…
Hydrogenated atmospheres of lava planets: atmospheric structure and emission spectra
Aurélien Falco, Pascal Tremblin, Sébastien Charnoz +2
Hot rocky super-Earths are thought to be sufficiently irradiated by their host star to melt their surface and thus allow for long-lasting magma oceans. Some processes have been pro…
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…
The role of interior dynamics and differentiation on the surface and atmosphere of lava planets
Charles-Édouard Boukaré, Daphné Lemasquerier, Nicolas Cowan +5
Lava planets are rocky exoplanets that orbit so close to their host star that their day-side is hot enough to melt silicate rock. Their short orbital periods ensure that lava plane…
The effect of a small amount of hydrogen in the atmosphere of ultrahot magma-ocean planets: atmospheric composition and escape
Sébastien Charnoz, Aurélien Falco, Pascal Tremblin +3
Here we investigate how small amounts of hydrogen (much smaller than the mass of the exoplanet) above a magma ocean on a rocky exoplanet may modify the atmospheric chemistry and at…
Toward a multidimensional analysis of transmission spectroscopy. Part III: Modelling 2D effects in retrievals with TauREx
Tiziano Zingales, Aurélien Falco, William Pluriel +1
New-generation spectrographs dedicated to the study of exoplanetary atmospheres require a high accuracy in the atmospheric models to better interpret the input spectra. Thanks to s…
Toward a multidimensional analysis of transmission spectroscopy. Part I: Computation of transmission spectra using a 1D, 2D, or 3D atmosphere structure
Aurélien Falco, Tiziano Zingales, William Pluriel +1
Considering the relatively high precision that will be reached by future observatories, it has recently become clear that one dimensional (1D) atmospheric models, in which the atmo…
Towards multi-dimensional analysis of transmission spectroscopy. Part II: Day-night induced biases in retrievals from hot to ultra-hot Jupiters
William Pluriel, Jeremy Leconte, Vivien Parmentier +4
Hot Jupiters are very good targets for transmission spectroscopy analysis. Their atmospheres have a large scale height implying a high signal to noise ratio. As these planets orbit…
