Description Our knowledge of planetary systems outside of ours is confined almost entirely to cases where the planets are close to the star. A critical stage in the development of the Solar System was the stabilization of the orbits of Jupiter and Saturn far from the Sun. What are the characteristics of other planetary systems at large radii? Planetary debris disks provide our best tool to answer this question. However, our interpretation of these systems is currently crippled by the lack, in most cases, of more information beyond a few photometric points on a spectral energy distribution. Such data can be fitted by a broad variety of quite different disk models. Resolved Herschel images of disks can provide much better constraints on models and can lead to sufficient understanding of the general behavior to help interpret even those systems where resolved images are not possible. We have identified 17 bright disks that show marginally resolved structures in Spitzer data, suggesting a radial size of cold planetesimal belt 3 to 10 times larger than our own Kuiper Belt. Since the disk mass is proportional to the disk diameter and covering factor of the dust, these systems are likely to be associated with the most massive planetary systems, making them the possible sites where the richest, most massive and extended families of planets will form. We propose to image these disks that can be resolved well at PACS 70 micron but not in any existing Herschel programs. We will use the resolved images as well as the photometric data obtained with SPIRE to probe: (1) the properties of cold planetesimal belts as signposts of ice giants at large orbits, and (2) the diversity of outermost planetesimal zones around other stars and the underlying causes.

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.
