Although many hundreds of debris disks have been discovered overthe past three decades, these stars are widely diversed in termsof ages, distances, reliabilities, levels of dustcharacterization, etc. Nearest debris disks are most interestingbecause they are brighter and larger than more distant similardebris disks. By collecting all known debris disks in theliterature, we re-analyzed all debris disks (about 1800) in ahomogeneous way using the state-of-the-art photosphere fittingmethod and including the newest available data including WISE. Out of thisreanalysis, we selected 123 nearby (d<100c) bona-fide debris diskswhere almost a half of them have a dust excess measurement at onlyone passband. To constrain dust properties for these nearby debrisdisks, we request to obtain 100 and 160 micron measurements withHerschel/PACS. The result of this proposed study will be acomplete inventory of known debris disks within 100pc with fullyconstrained dust properties. Such an inventory will be anindispensable asset for any future debris disk studies with ALMA,SOFIA, SPICA, etc. |
