论文摘要

我们完成对KMTNET隔离剂鉴定的所有2018年原场微覆盖行星的分析。在具有清晰行星解决方案的10个以前未发表的事件中，有8个是明确的行星，或者很可能是行星本质上是行星的：Ogle-2018-Blg-1126，KMT-2018-Blg-2004，Ogle-2018-Blg-2018-Blg-1647 OGLE-2018-BLG-1212和KMT-2018-BLG-2718。再加上4个先前发表的新的Anomalyfinder事件和12个先前出版的行星（或在制备中）被眼睛发现的行星，这将是由Anomalyfinder发现或回收的2018年24个Prime-Field Planets。这项工作与在2018年亚电场行星上准备的论文一起为行星质量比率函数的首次统计分析基于基于KMTNET数据中确定的行星的基础。通过系统地应用Hwang等人的启发式分析。（2022）对于每个事件，我们在其形式主义中确定了统一所谓的近距/宽/宽/外部/外部变性所需的小修改，这是由

We complete the analysis of all 2018 prime-field microlensing planets identified by the KMTNet AnomalyFinder. Among the 10 previously unpublished events with clear planetary solutions, 8 are either unambiguously planetary or are very likely to be planetary in nature: OGLE-2018-BLG-1126, KMT-2018-BLG-2004, OGLE-2018-BLG-1647, OGLE-2018-BLG-1367, OGLE-2018-BLG-1544, OGLE-2018-BLG-0932, OGLE-2018-BLG-1212, and KMT-2018-BLG-2718. Combined with the 4 previously published new AnomalyFinder events and 12 previously published (or in preparation) planets that were discovered by eye, thismakes a total of 24 2018 prime-field planets discovered or recovered by AnomalyFinder. Together with a paper in preparation on 2018 sub-prime planets, this work lays the basis for the first statistical analysis of the planet mass-ratio function based on planets identified in KMTNet data. By systematically applying the heuristic analysis of Hwang et al. (2022) to each event, we identify the small modification in their formalism that is needed to unify the so-called close/wide and inner/outer degeneracies, as conjectured by
