We propose to measure with PACS the broadband far-infraredspectrum of some young A- and F-type main sequence stars with known,exceptionally luminous, mid-infrared emission. Such stars are uncommonbut are of special interest because they point to and delineate the era ofrocky terrestrial planet formation. Herschel observations will establishwhether cool dusty regions analogous to the Suns Kuiper Belt regionaccompany inner regions where terrestrial planet formation is occurring.

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.
