Although many hundreds of debris disks have been discovered over the past three decades, these stars are widely diversed in terms of ages, distances, reliabilities, levels of dust characterization, etc. Nearest debris disks are most interesting because they are brighter and larger than more distant similar debris disks. By collecting all known debris disks in the literature, we re-analyzed all debris disks (about 1800) in a homogeneous way using the state-of-the-art photosphere fitting method and including the newest available data including WISE. Out of this reanalysis, we selected 123 nearby (d<100[c) bona-fide debris disks where almost a half of them have a dust excess measurement at only one passband. To constrain dust properties for these nearby debris disks, we request to obtain 100 and 160 micron measurements with Herschel-PACS. The result of this proposed study will be a complete inventory of known debris disks within 100pc with fully constrained dust properties. Such an inventory will be an indispensable asset for any future debris disk studies with ALMA, SOFIA, SPICA, etc. |
