Scientific paper

We use Spitzer data and the WISE preliminary release to explore the incidence and relationship of warm dust in the habitable zones around exoplanet-host stars. We study the SED of about 300 planet-bearing stars to 1) identify excess emission at 12 and 22 microns (dust at ? and ? K), and 2) perform detailed photosphere-subtractions using Spitzer data of previously known warm disks.
Our project yields, the most extensive catalog of warm disks tracing events in the terrestrial-planet zones around exoplanet-host stars, providing observers an advantage for ground- and space-based follow-up imaging, and to inform next-generation mission designs.
