Description Debris disks are the signposts of planetary systems: collisions
among asteroidal and cometary parent bodies maintain the
observed dust population against losses to radiation pressure
and P-R drag. While hundreds of debris disks are known from
far-IR excecss emission around main sequence stars, the best-
understood systems are the virgul20 that are spatially resolved.
Disk images establish the size scale of an exoplanetary system.
They can reveal central holes, rings, gaps, warps, and asymmetries
in the dust distribution which indicate the presence of planetary
perturbers. Disk images at different wavelengths are sensitive to
dust grains of different sizes, and thus provide a way to trace dust
transport and segregation processes.

In spring 2011 we discovered large new debris disk in HST
coronagraphic images. The new system is an eccentric ring with
a sharp inner edge and cleared central zone, and thus is remarkably
similar to the classic Fomalhaut debris ring. Spitzer only detected
the system at a single wavelength. We propose PACS and SPIRE
imaging photometry to fully establish the spatial and spectral
properties of this new debris system, and of three other
HST-detected debris disks that lack Herschel measurements.
Simultaneous modeling of the far-IR images, SEDs, and HST images
of these disk will provide important constraints on the physical
properties and dynamical state of their constituent dust.
Our small program will complete Herschel.s legacy dataset for
the key subsample of bright disks that are detected in
scacttered light,

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 µm range, bridging the gap between earlier infrared space missions and groundbased facilities.
