Description Debris disks are analogs of our Kuiper Belt in the periphery of the Solar System, but are surrounding other main sequence stars. Comets in the Kuiper Belt, and more generally planetesimals in a debris disk, are left over from the early phase of planet formation according to the ..core-accretion" theory and are connected to a planetary system orbiting closer in. Differently, an alternative theory for the formation of giant planets distant from their star invokes ..gravitational instabilities.. in young, large, and massive protoplanetary disks, and predicts no left over planetesimal in a peripheral disk at the end this fast process. Hence, existence and sizes of debris disks are a central question in planet formation theory. The PLANCK in-orbit observatory is conducting the first all-sky survey in the submillimeter and offers the first opportunity for an unbiased survey of very large, and cold debris disks. We have used the existing PLANCK data to identify debris disk candidates spatially unresolved with the PLANCK beam (4.2.). We propose to confirm their nature by spatially resolving them with the Herschel SPIRE camera, and to determine their sizes by imaging and dust temperature by sampling their SED at 250, 350 and 500 mu m. If successful, we would have identified a new population of very large, and cold debris disks characterized by distant planetesimals from their central star, supporting the ..core-accretion.. theory for giant planet formation.

Mission Description Herschel was launched on 14 May 2009! It is the fourth 'cornerstone' mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 ┬Ám range, bridging the gap between earlier infrared space missions and groundbased facilities.
