'Infrared Observations of Exoplanet Atmospheres'

Transiting extrasolar planets offer the unique possibility to constrain the mass, radius, and atmospheric properties of these objects. Because of their temperatures (>700 K, and typically hotter) the atmospheres of these planets are predicted to contain diverse molecular species; for this reason, and because these planets emit the bulk of their radiation in the near- to mid-infrared, infrared observations offer the potential to constrain the composition, structure, and perhaps the origin of their atmospheres. I will discuss some new results from the Spitzer Space Telescope, but will focus on my efforts to exploit the potential of ground-based NIR spectroscopy: initial results for several systems, lessons learned, and the great promise of multi-object spectrographs, which are poised to revolutionize the field.
