Astronomy Colloquium - "Probing the Weather on Distant Worlds"
The number of planets detected outside of our solar system has
increased at an almost exponential rate over the past 10 years with
currently more than 1800 confirmed exoplanets. Slowly, we are
beginning to characterize the physical properties of these planets
including their atmospheric composition, thermal structure, and global
circulation patterns. Here I discuss the combination of sophisticated
three-dimensional atmospheric models with space-based observations to
probe weather patterns in exoplanet atmospheres. I will focus on
recent phase-curve and eclipse-mapping observations with the Spitzer
Space Telescope aimed at characterizing the global circulation
patterns of extrasolar planets. The combination of these observations
with atmospheric models will hopefully shed new light on the
radiative, dynamic, and chemical process that are at work in these
atmospheres beyond our solar system.
