论文摘要
纬度密度搜索利用了Subaru望远镜上的超级表面胶卷，发现外部太阳系中的60个移动物体，其中54个具有30 au以上的半毛轴。 The images were acquired in exceptional seeing (0.4") and reached a detection limit of m_r~=25.2. The two night arcs were used to calculate orbits which are poorly constrained, however, the distance and inclination are the parameters best constrained by short arcs and a reasonable determination can be made of which objects are cold classical TNOs and which are dynamically excited. We identify 10 objects as likely cold classical objects. We searched all of the使用尾随点扩散函数减法方法检测二进制源，并鉴定出一个分离为0.34英寸的二进制对象，而次要的二进制对象则是初级亮度为17％的次级对象（2.0个幅度较大）。这是样品中最亮的TNO，即先前已知的对象471165（2010 HE79），它具有动态激发的轨道。由于观看良好，此搜索对二进制敏感，分离为0.34英寸，亮度为> = 50％，是7个物体的主要亮度，包括一个冷时光，这给出了〜17％的固有二进制分数（1 of 6）（1 of 6），用于在我们的检测范围内动态激发的对象，以确定两种complient fight fight fight fight fight interive。密度搜索是一种有用的工具，可以更广泛地应用于识别二进制TNO和跟踪已知的二进制TNO轨道。
The Latitude Density Search utilized Hyper Suprime-Cam on Subaru Telescope to discover 60 moving objects in the outer Solar System, 54 of which have semi-major axes beyond 30 AU. The images were acquired in exceptional seeing (0.4") and reached a detection limit of m_r~=25.2. The two night arcs were used to calculate orbits which are poorly constrained, however, the distance and inclination are the parameters best constrained by short arcs and a reasonable determination can be made of which objects are cold classical TNOs and which are dynamically excited. We identify 10 objects as likely cold classical objects. We searched all of the detections for binary sources using a trailed Point Spread Function subtraction method, and identified one binary object with a separation of 0.34" and a secondary with 17% the brightness of the primary (2.0 magnitudes fainter). This is the brightest TNO in the sample, the previously known object 471165 (2010 HE79), which has a dynamically excited orbit. Because of the excellent seeing, this search was sensitive to binaries with 0.34" separation and a brightness of >=50% the primary brightness for 7 objects, including one cold classical. This gives an intrinsic binary fraction of ~17% (1 of 6) for the dynamically excited objects within our detection limits. The trailed point spread function subtraction method to identify binaries, fit the two components, and determine the sensitivity limits, used in the Latitude Density Search is a useful tool that could be more broadly applied to identify binary TNOs and track known binary TNO orbits.
