Cataloging Debris Disks within 100pc

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

尽管在过去三十年间已发现数百个碎片盘，但这些恒星在年龄、距离、可靠性以及尘埃特征水平等方面呈现出广泛的多样性。邻近的碎片盘因其亮度更高、尺寸更大而尤为引人注目，相较于更远的同类碎片盘。通过收集文献中所有已知的碎片盘（约1800个），我们以统一的方式重新分析了这些碎片盘，采用了最先进的球面拟合方法，并纳入了包括WISE在内的新数据。在此重新分析的基础上，我们选取了123个位于附近（距离小于100光年）的可靠碎片盘，其中近一半的碎片盘仅在一个波段内进行了尘埃过剩的测量。为了限制这些邻近碎片盘的尘埃特性，我们请求使用赫歇尔/PACS获取100和160微米的测量数据。本拟议研究的结果将是一个包含已知100光年内碎片盘的完整清单，其中尘埃特性得到完全约束。这样一个清单将成为任何未来使用ALMA、SOFIA、SPICA等设施进行碎片盘研究的不可或缺的资源。[截断！请参阅实际数据以获取全文][截断！请参阅实际数据以获取全文]
