The study of exoplanets is undergoing a revolution, with current telescopes capable of probing the atmospheres of distant worlds in unprecedented detail. My current project aims to bridge the gap between observational data and existing modeling efforts by developing high-resolution atmospheric simulations that incorporate chemical disequilibrium processes. Adopting an observation-centered approach, I will simulate the transmission spectra of transit exoplanets while building on the theoretical foundations of state-of-the-art photochemical kinetics models. Within the scope of the GAPS collaboration, I will conduct simulations of the expected transmission spectra of HD 209458 b under various chemical disequilibrium regimes, investigating species-by-species changes in the expected observed spectrum over the duration of the transit and probing for the presence of morning-evening limb asymmetries.
