论文摘要
我们分析了大量公民科学数据，并确定了八个热木星系统，这些系统显示出与恒定轨道时期偏差的证据：HAT-P-19 B，HAT-P-32 B，TRES-1 B，TRES-1 B，TRES-2 B，TRES-5 B，TRES-5 B，WASP-4 B，WASP-4 B，WASP-10 B，WASP-10 B和WASP-12 B。后一种系统已经众所周知，可以表现出有力的潮汐轨道衰减证据，并作为本研究的重要控制。我们确定的其他几个系统在文献中存在争议的时期漂移，从而使这里的结果可以作为独立分析。公民科学数据来自外部运输数据库（ETD），该数据库是一个全球项目，该项目由捷克天文学学会的可变星和系外行星部分于2008年建立。 ETD拥有超过400个行星和12,000个贡献的观察结果，涉及15年的观测，这可能是研究近距离热木星的长期轨道演变的潜力。我们使用结果来讨论目标的优先级以进行后续调查，这对于确认时期漂移及其原因是必要的。
We analyze a large number of citizen science data and identify eight Hot Jupiter systems that show evidence for deviations from a constant orbital period: HAT-P-19 b, HAT-P-32 b, TrES-1 b, TrES-2 b, TrES-5 b, WASP-4 b, WASP-10 b, and WASP-12 b. The latter system is already well known to exhibit strong evidence for tidal orbital decay and serves as an important control for this study. Several other systems we identify have disputed period drifts in the literature, allowing the results here to serve as an independent analysis. The citizen science data are from the Exoplanet Transit Database (ETD), which is a global project established in 2008 by the Variable Star and Exoplanet Section of the Czech Astronomical Society. With over 400 planets and 12,000 contributed observations spanning 15 years, the ETD is brimming with potential for studying the long-term orbital evolution of close-in Hot Jupiters. We use our results to discuss prioritization of targets for follow up investigations, which will be necessary to confirm the period drifts and their causes.
