Probing Exoplanetary Chemistry with Ariel: Scientific Priorities and Observational Strategies

Olivia Venot, Yamila Miguel, Robin Baeyens +30

Over the past two decades, increasingly precise observations have revealed that exoplanet atmospheres are chemically diverse and often far from equilibrium, with processes such as…

Possible favored Great Oxidation Event scenario on exoplanets around M-Stars with the example of TRAPPIST-1e

Adam Y. Jaziri, Nathalie Carrasco, Benjamin Charnay

The Great Oxidation Event (GOE), which marked the transition from an anoxic to an oxygenated atmosphere, occurred 2.4 billion years ago on Earth, several hundreds of millions of ye…

Understanding the chemistry of temperate exoplanets atmospheres through experimental and numerical simulations

O. Sohier, A. Y. Jaziri, L. Vettier +3

Characterizing temperate exoplanet atmospheres remains challenging due to their small size and low temperatures. Recent JWST observations provide valuable data, but their interpret…

Investigating aerosols as a way to reconcile K2-18 b JWST MIRI and NIRISS/NIRSpec observations

Adam Yassin Jaziri, Thomas Drant

Recent JWST observations of the temperate sub-Neptune K2-18 b with NIRISS SOSS/NIRSpec G395H and MIRI LRS have yielded apparently inconsistent results: the MIRI spectra exhibit spe…

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…

Homogeneous search for helium in the atmosphere of 11 gas giant exoplanets with SPIRou

R. Allart, P. -B. Lemée-Joliecoeur, A. Y. Jaziri +31

The metastable helium triplet in the near-infrared (10833Å) is among the most important probes of exoplanet atmospheres. It can trace their extended outer layers and constrain mass…

Dynamics of the Great Oxidation Event from a 3D photochemical-climate model

Adam Yassin Jaziri, Benjamin Charnay, Franck Selsis +2

From the Archean toward the Proterozoic, the Earth's atmosphere underwent a major shift from anoxic to oxic conditions, around 2.4 to 2.1 Gyr, known as the Great Oxidation Event (G…

ARES IV: Probing the atmospheres of the two warm small planets HD 106315 c and HD 3167 c with the HST/WFC3 camera

Gloria Guilluy, Amélie Gressier, Sam Wright +27

We present an atmospheric characterization study of two medium sized planets bracketing the radius of Neptune: HD 106315 c (R=4.98 0.23 R) and HD 3167 c…

ARES II: Characterising the Hot Jupiters WASP-127 b, WASP-79 b and WASP-62 b with HST

Nour Skaf, Michelle Fabienne Bieger, Billy Edwards +24

This paper presents the atmospheric characterisation of three large, gaseous planets: WASP-127b, WASP-79b and WASP-62b. We analysed spectroscopic data obtained with the G141 grism…

ARES I: WASP-76 b, A Tale of Two HST Spectra

Billy Edwards, Quentin Changeat, Robin Baeyens +25

We analyse the transmission and emission spectra of the ultra-hot Jupiter WASP-76b, observed with the G141 grism of the Hubble Space Telescope's Wide Field Camera 3 (WFC3). We redu…

On the reservoir of sulphur in dark clouds : chemistry and elemental abundance reconciled

Thomas H. G. Vidal, Jean-Christophe Loison, Adam Yassin Jaziri +3

Sulphur-bearing species are often used to probe the physical structure of star forming regions of the interstellar medium, but the chemistry of sulphur in these regions is still po…
