Exoplanetary Atmospheres : Theory and Simulation

Kevin Heng (University of Bern) Thursday June 19th - 11am IPAG Seminar Room - IPAG

With the detection of exoplanets now a firmly established cottage industry, attention has turned to the characterization of their atmospheres. Initial efforts have focused on hot, large exoplanets : hot Jupiters and directly imaged exoplanets. In this seminar, I will review a ’tasting menu’ with three components, so as to give a flavor of my group’s activities at the University of Bern, Switzerland. First, I will summarize observational highlights from a theorist’s perspective. Second, I will review theoretical ideas and outstanding puzzles. Third, I will describe why current climate simulators are inadequate for the study of hot exoplanets and the steps we need to take to upgrade them. I will end with perspectives on the future, including the search for more exoplanets around bright stars and why we should abandon (or at least, talk less about) the idea of habitable zones. Technical topics covered include radiative transfer, atmospheric retrieval and general circulation models.
