31 -- Spectra of Asteroid Belts, Kuiper Belts, and Giant Planets

Description
Ongoing observations from the Spitzer Space Telescope include photometry and spectroscopy of material in the asteroid and Kuiper Belts of nearby main sequence stars, as well as photometry and spectroscopy of hot Jupiters (transits and complete light curves). The debris disk data, along with IR spectra of comets within our own solar system, are leading to our improved understanding of nature and distribution of volatiles in other solar systems, information critical to understanding the origin of these species on the early Earth. The transit spectroscopy of hot Jupiters is revealing the presence (and absence) of water vapor in a number of planets. We will discuss Spitzer observations, as well as present talks on the dramatic role that NASA's next flagship mission in astrophysics, the James Webb Space Telescope, will play in advancing our understanding of volatiles and organic material in extrasolar planetary systems.
