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…
Unraveling the non-equilibrium chemistry of the temperate sub-Neptune K2-18 b
A. Y. Jaziri, O. Sohier, O. Venot +1
The search for habitable, Earth-like exoplanets faces major observational challenges due to their small size and faint signals. M-dwarf stars offer a promising avenue to detect and…
