在塞德娜地区寻找遥远的太阳系天体

A Search for Distant Solar System Bodies in the Region of Sedna

Megan E. Schwamb, Michael E. Brown, David L. Rabinowitz

摘要:

本文介绍了利用帕洛玛天文台的1.2米Samuel Oschin望远镜对外太阳系遥远的类塞德娜天体进行的宽视场观测的结果。我们搜索了约12,000平方度,直到R的平均极限星等21.3。总共探测到53个柯伊伯带天体和半人马座,其中25个是在这次调查中发现的。没有额外的塞德娜一样的机构与近日点超过70 AU被发现,尽管一个敏感的议案了~1000 AU。我们对赛德娜轨道上物体的大小和分布进行了限制。

英文摘要:

We present the results of a wide-field survey for distant Sedna-like bodies in the outer solar system using the 1.2-m Samuel Oschin Telescope at Palomar Observatory. We searched ~12,000 square degrees down to a mean limiting magnitude of 21.3 in R. A total number of 53 Kuiper belt objects and Centaurs have been detected; 25 of which were discovered in this survey. No additional Sedna-like bodies with perihelia beyond 70 AU were found despite a sensitivity to motions out to ~1000 AU. We place constraints on the size and distribution of objects on Sedna orbits.
