Research Division Seminar
IAU G5: Transiting Giant Planet Atmospheres: Physics, Chemistry, and First JWST Observations

Dr. Jonathan Fortney

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!
