Talk by Joe Carson, College of Charleston

I present two ongoing surveys to directly image extrasolar planets in infrared light. The ground-based survey component involves a Subaru Telescope adaptive optics search for mid-separation (>20AU) gas-giant planets around early type stars. The space-based component entails the use of the Spitzer Space Telescope to search for wide separation (>100AU) planets and brown dwarfs around stars that are already known to harbor inner planets (<3AU), as determined from Doppler spectroscopy surveys. I describe the current status of these surveys as well as show preliminary results.
