标题： A serendipitous all sky survey for bright objects in the outer solar system

摘要： 我们使用来自卡特琳娜巡天和斯廷宁弹簧巡天的七年的观测数据，这些数据覆盖了大部分北半球和南半球的银纬高于20度的区域，以寻找外太阳系中偶然成像的移动天体。 这些缓慢移动的天体在这两个快速拍摄的小行星巡天项目中会表现为静止的暂现源，因此我们开发了方法，利用间隔数月而不是通常数小时的单次观测来发现外太阳系中的天体。 虽然我们独立发现了外太阳系中8个已知的明亮天体，其中最暗的为$V=19.8\pm0.1$，但没有发现新的天体。 我们发现，对于$V\lesssim 19.1$（南半球为$V\lesssim18.6$），该巡天在外围超过25AU的天体探测效率接近100%，而在银河平面未被勘测的区域中，存在一个或多个同样亮度的剩余外太阳系天体的概率约为32%。 显示英文摘要

摘要： We use seven year's worth of observations from the Catalina Sky Survey and the Siding Spring Survey covering most of the northern and southern hemisphere at galactic latitudes higher than 20 degrees to search for serendipitously imaged moving objects in the outer solar system. These slowly moving objects would appear as stationary transients in these fast cadence asteroids surveys, so we develop methods to discover objects in the outer solar system using individual observations spaced by months, rather than spaced by hours, as is typically done. While we independently discover 8 known bright objects in the outer solar system, the faintest having $V=19.8\pm0.1$, no new objects are discovered. We find that the survey is nearly 100% efficient at detecting objects beyond 25 AU for $V\lesssim 19.1$ ($V\lesssim18.6$ in the southern hemisphere) and that the probability that there is one or more remaining outer solar system object of this brightness left to be discovered in the unsurveyed regions of the galactic plane is approximately 32%.
