Exoplanet Atmosphere Characterization in the Run-Up to JWST 

Laura Kreidberg - Harvard University 

I will discuss the current state of the art in exoplanet atmosphere studies from space. The talk will focus on several case studies -- WASP-43b, WASP-12b, WASP-103b, and GJ 1214b -- for which we have obtained JWST-quality spectra using intensive observing campaigns with the Hubble and Spitzer Space Telescopes.

I will describe the implications of these results for the planets' current climates as well as their formation and evolutionary histories. Finally, I will discuss prospects for future characterization efforts with JWST and beyond.

Coffee and Donuts will be served at 2:00pm in 4054 McPherson Lab.
