IAU G5: Transiting Giant Planet Atmospheres: Physics, Chemistry, and First JWST Observations
Abstract
Unlike the giant planets in the solar system, "hot Jupiter" giant exoplanets are subject to intense stellar irradiation, which drives their atmospheres from ~100 K (in the solar system) to ~1000 to 3000 K. In this talk I will review several aspects of their atmospheric physics and chemistry, with a particular emphasis on the cooler "warm Jupiters" below 1000 K where we expect to see some interesting transitions in atmospheric chemistry and clouds with JWST. I will discuss new JWST spectra and modeling work on 1100 K exoplanet WASP-39b, which will be published in Nature in a few days time, as part of the JWST Early Release Science (ERS) program. The spectra show some expected things but also some very interesting surprises!
