论文摘要
我们根据NASA Transiting系外行星调查卫星（TESS）的数据为382个行星提供了一个过境时间和更新胚层数据库，并以前报道的过境时间以半自动化的方式从文献中划出。总体而言，我们的数据库包含382个系统的8,667个运输时间测量。目录中的大约240个行星是热木星（即，质量为$> $> $> $ 0.3 $ m _ {\ rm jup} $的行星，苔丝已经观察到的$ <rm jup} $，周期$ <$ <$ <$ <10天）。新的ephemerides对于安排后续观察和寻找长期更改很有用。 WASP-12仍然是唯一可以牢固检测到周期更改的系统。我们评论其他感兴趣的案例，例如一些具有暗示性（但尚未令人信服的）时期变化的系统，以及在NGTS-11系统中检测第二个过境星球的证据。光曲线，过境时间，临时性和定时残差的汇编以及生成它们的Python代码（访问https://transit-timing.github.io）。
We provide a database of transit times and updated ephemerides for 382 planets based on data from the NASA Transiting Exoplanet Survey Satellite (TESS) and previously reported transit times which were scraped from the literature in a semi-automated fashion. In total, our database contains 8,667 transit timing measurements for 382 systems. About 240 planets in the catalog are hot Jupiters (i.e. planets with mass $>$0.3$M_{\rm Jup}$ and period $<$10 days) that have been observed by TESS. The new ephemerides are useful for scheduling follow-up observations and searching for long-term period changes. WASP-12 remains the only system for which a period change is securely detected. We remark on other cases of interest, such as a few systems with suggestive (but not yet convincing) evidence for period changes, and the detection of a second transiting planet in the NGTS-11 system. The compilation of light curves, transit times, ephemerides, and timing residuals are made available online, along with the Python code that generated them (visit https://transit-timing.github.io).
