[PAE18-06] Study of exoplanet atmospheres with next-gen space observatories (JWST, Ariel)

★Invited Papers

*Quentin Changeat1 (1.University of Groningen)

Keywords:Exoplanet Atmospheres, Space Telescopes, JWST, Ariel

The characterization of exoplanet atmospheres has entered a transformative era with the advent of next-generation space observatories. The James Webb Space Telescope (JWST) is already providing unprecedented insights into atmospheric composition, cloud dynamics, and thermal structures, while the upcoming Ariel mission will conduct a large-scale survey to reveal the chemical diversity of exoplanets. In this talk, I will discuss recent breakthroughs in exoplanet atmospheric studies, highlighting key results from JWST and the expected contributions of Ariel. By leveraging advanced spectroscopy and novel data analysis techniques, these missions are revolutionizing our understanding of planetary formation, habitability, and the broader context of exoplanetary science.
