| Description |
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. |
