标题： A Pan-STARRS Search for Distant Planets: Part 1

摘要： 我们开展了基于全景巡天望远镜和快速反应系统1（Pan-STARRS1）的遥远行星搜寻工作。 我们通过向Pan-STARRS1源表注入各向同性的控制样本——一组合成探测，来校准我们的搜寻方法，这提供了一个比在图像级别注入合成源更精确的替代方案。 我们发现，我们的方法能够探测到广泛的距离范围以及所有运动速率和方向。 我们识别出692个太阳系天体（其中109个尚未列入小行星中心数据库），其中包括642个柯伊伯带天体（TNOs），其中有23颗是矮行星。 就探测数量而言，尽管我们并未明确搜寻距太阳小于80天文单位的天体，但这次搜寻仍是迄今为止第三大最成功的柯伊伯带巡天任务。 虽然我们没有找到第九行星或任何其他行星天体，但我们能够表明，第九行星剩余的参数空间高度集中在银河平面内。 显示英文摘要

摘要： We present a search for distant planets in Pan-STARRS1. We calibrated our search by injecting an isotropic control population of synthetic detections into Pan-STARRS1 source catalogs, providing a high-fidelity alternative to injecting synthetic sources at the image level. We found that our method is sensitive to a wide range of distances, as well as all rates and directions of motion. We identified 692 solar system objects (109 of which are not yet listed in the Minor Planet Center's database), including 642 TNOs, 23 of which are dwarf planets. By raw number of detections, this makes our search the third most productive Kuiper Belt survey to date, in spite of the fact that we did not explicitly search for objects closer than 80 au. Although we did not find Planet Nine or any other planetary objects, we were able to show that the remaining parameter space for Planet Nine is highly concentrated in the galactic plane.
