The James Webb Space Telescope recently provided the first evidence of atmospheres around rocky exoplanets. The interpretation of spectroscopic observations and the climate predictions remain however limited by the lack of experimental data.

Experimental photochemistry can provide crucial insights into the chemical mechanisms shaping the evolution of habitable worlds as well as provide fundamental data to characterize the optical properties of photochemical hazes. Atmospheric modeling allows us to evaluate the importance of specific mechanisms on climate, chemistry and observations taking into account the complex interactions between interior, surface and atmosphere.

During this seminar, I will present the different types of observables expected in JWST spectra of rocky exoplanet atmospheres and discuss the information they can provide on the habitability and interior properties of these planets.
