论文摘要
对外太阳系中最遥远的库珀带物体的聚类的研究暗示了海王星以外的行星可能存在，被称为九（P9）。最近的努力限制了P9轨道元素的参数空间，从而创建了假设P9的合成目录。通过检查许多天空调查中这种目录的潜在恢复，可以进一步限制P9的参数空间，从而为更具针对性的搜索提供了方向。我们研究了整个六年的黑暗能源调查（DES）恢复在Brown和Batygin（2021a）中恢复九个人群的合成行星的能力[ARXIV：2108.09868]。我们发现，在100,000个模拟对象中，有11,709个穿越广泛的调查足迹，其中1187（87.0％）被回收。这将排除在考虑行星九个行星之后的另外5％的参数空间。
Studies of the clustering of the most distant Kuiper belt objects in the outer solar system have hinted at the possible existence of a planet beyond Neptune referred to as Planet Nine (P9). Recent efforts have constrained the parameter space of the orbital elements of P9, allowing for the creation of a synthetic catalog of hypothetical P9s. By examining the potential recovery of such a catalog within numerous sky surveys, it is possible to further constrain the parameter space for P9, providing direction for a more targeted search. We examine the ability of the full six years of the Dark Energy Survey (DES) to recover a synthetic Planet Nine population presented in Brown and Batygin (2021a) [arXiv:2108.09868]. We find that out of 100,000 simulated objects, 11,709 cross the wide DES survey footprint of which 10,187 (87.0%) are recovered. This rules out an additional 5% of the parameter space after accounting for Planets Nine that would have been detected by both the Zwicky Transient Facility and DES.
