论文摘要
我们为K2任务的竞选5提出了统一的过境系外行星候选名单。该目录包含75个行星,上面有7个多星际系统(5个双重,1个三重和1个四个四个行星系统)。在我们的搜索范围内,我们发现了8名未被发现的候选人,其余66名候选人重叠了Kruse等人的51%。研究该手动审查5个候选人。为了审查我们的潜在运输信号,我们介绍了外部玩家检测识别(Edi-Vetter),该识别(EDI-VETTER)是一个完全自动化的程序,能够确定是否应将过境信号标记为假阳性或行星候选者。这种自动化使我们能够创建一个统计统一的目录,非常适合行星发生率测量。经过测试后,审核软件能够确保我们的样本在系统的误报方面可靠94.2%。此外,我们在RAW K2数据的光曲线级别注入人造转运,发现管道的最大完整性为70%,审查前为60%,审查后60%。为了方便未来的发生率研究,我们包括对每个目标的恒星噪声(CDPP)的测量值(CDPP)和三透明窗口函数。这项研究是对K2数据集的更大调查的一部分,以及将应用于整个K2数据集的方法。
We present a uniform transiting exoplanet candidate list for Campaign 5 of the K2 mission. This catalog contains 75 planets with 7 multi-planet systems (5 double, 1 triple, and 1 quadruple planet system). Within the range of our search, we find 8 previously undetected candidates with the remaining 66 candidates overlapping 51% of the Kruse et al. study that manually vet Campaign 5 candidates. In order to vet our potential transit signals, we introduce the Exoplanet Detection Identification Vetter (EDI-Vetter), which is a fully automated program able to determine if a transit signal should be labeled as a false positive or a planet candidate. This automation allows us to create a statistically uniform catalog, ideal for planet occurrence rate measurements. When tested, the vetting software is able to ensure our sample is 94.2% reliable against systematic false positives. Additionally, we inject artificial transits at the light-curve-level of the raw K2 data and find the maximum completeness of our pipeline is 70% before vetting and 60% after vetting. For convenience of future occurrence rate studies, we include measurements of stellar noise (CDPP) and the three-transit window function for each target. This study is part of a larger survey of the K2 data set and the methodology which will be applied to the entirety of the K2 data set.
