Author currie, t.
Description We propose sensitive PACS and SPIRE imaging photometry of four stars with important debris disks yet to be imaged with Herschel. Two of these stars (EF Cha and HD 165014) have warm debris disks *and* complex mid-IR spectral structures that provide evidence for critical terrestrial planet formation processes: the formation of large, differentiated bodies and terrestrial water delivery. Two (HD 15115 and HD 61005) have colder, extended Kuiper belt-like disks with newly discovered structures likely induced by massive jovian planets. Our PACS imaging of the first sample will help determine whether these terrestrial planet-forming systems also have Kuiper belts, features crucial to interpreting the planet-forming potential of these systems. Our PACS-SPIRE imaging of HD 15115 and HD 61005 will spatially resolve their disks to identify additional signatures of embedded planets and will constrain the disk far-IR slope and thus shed light on the collisional states of two debris disks perturbed by a planets.

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.
