Until recently, debris disk identification and study has been accomplishedmostly with the 30 year old IRAS all-sky survey (and small number of pointedobservations by Spitzer) and it has been limited to larger cold disks. Studyof warm debris disks can provide important information concerning terrestrialplanet formation and evolution, however, their identification andcharacterization has been restriected to a very small number of discovered warmdebris disks (N<10). The Wide-Field Infrared Explorer (WISE) has surveyed theentire sky at mid-IR wavelenghts, and the WISE survey provides almost 100 timesbetter photometric sensitivity than IRAS and approximately 10 timesbetterpositional accuracy. Using this improved information and sophisticatedtarget selection criteria, we have identified a complete, well-defined group of30 nearby (d < 100 pc) Hipparcos main-sequence stars showing the indication ofwarm debris disks. With nine of these stars being observed as part of anexisting Herschel program, we propose to observe the remaining 21 stars tocomplete a census of warm debris disks in the solar neighborhood. With HerschelPACS measurements at 70 and 160 micron, we can fully constrain dust temperatureand dust quantity around this rare group of stars.

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.
