论文摘要
我们完成对KMTNET隔离式识别的所有2018年亚电场微透镜行星的分析。在有清晰行星解决方案的9个以前未发表的事件中，有6个显然是行星（KMT-2018-BLG-0030，KMT-2018-BLG-0087，KMT-2018-BLG-0247，OGLE-2018-BLG-2018-BLG-0298 自然。此外，有8个先前发表的次级田间行星是由Anomleyfinder算法选择的。这项工作与2018年主要场行星的同伴论文（Gould等人2022）一起为基于KMTNET数据中确定的行星对行星质量比率函数进行首次统计分析的基础。正如预期的那样（Zhu等人，2014年），2018年行星中有一半（17/33）可能进入质量比率分析具有非毒事的异常。但是，在5个具有行星 - 宿主质量比$ q <10^{ - 3} $的非燃烧异常中，只有1个是通过Eye发现的（与12个$ Q> 10^{ - 3} $相比，有7个），显示了半自动化的anomalyalyfinder搜索的重要性。
We complete the analysis of all 2018 sub-prime-field microlensing planets identified by the KMTNet AnomalyFinder. Among the 9 previously unpublished events with clear planetary solutions, 6 are clearly planetary (KMT-2018-BLG-0030, KMT-2018-BLG-0087, KMT-2018-BLG-0247, OGLE-2018-BLG-0298, KMT-2018-BLG-2602, and OGLE-2018-BLG-1119), while the remaining 3 are ambiguous in nature. In addition, there are 8 previously published sub-prime field planets that were selected by the AnomalyFinder algorithm. Together with a companion paper (Gould et al. 2022) on 2018 prime-field planets, this work lays the basis for the first statistical analysis of the planet mass-ratio function based on planets identified in KMTNet data. As expected (Zhu et al. 2014), half (17/33) of the 2018 planets likely to enter the mass-ratio analysis have non-caustic-crossing anomalies. However, only 1 of the 5 non-caustic anomalies with planet-host mass ratio $q<10^{-3}$ was discovered by eye (compared to 7 of the 12 with $q>10^{-3}$), showing the importance of the semi-automated AnomalyFinder search.
