论文摘要
我们在开普勒字段中识别可能以运输时序变化（TTV）为特征的目标，并且可以通过过境外系仪卫星（TESS）检测到。尽管与开普勒相比，苔丝过渡的信噪比降低了，但我们从14、15、26、40和41的13个系统中恢复了48次转移。我们发现有力的有力证据表明，非传输驱动器绕开普勒-396（KOI-2672）（KOI-2672）（KOI-2672）（KOI-2672）（KOI-2672）（KOI-2672）（KOI-2672）（KOI-2672）（KOI-2672）（KOI-2672）并探索了该系统中的第三个行星，以解释该系统的三个可能的跨度跨度。 We update the ephemerides and mass constraints where possible at KOI-70 (Kepler-20), KOI-82 (Kepler-102), KOI-94 (Kepler-89), KOI-137 (Kepler-18), KOI-244 (Kepler-25), KOI-245 (Kepler-37), KOI-282 (Kepler-130), KOI-377（Kepler-9），KOI-620（Kepler-51），KOI-806（Kepler-30），KOI-1353（KEPLER-289）和KOI-1783（Kepler-1662）。
We identify targets in the Kepler field that may be characterized by transit timing variations (TTVs) and are detectable by the Transiting Exoplanet Survey Satellite (TESS). Despite the reduced signal-to-noise ratio of TESS transits compared to Kepler, we recover 48 transits from 13 systems in Sectors 14, 15, 26, 40 and 41. We find strong evidence of a nontransiting perturber orbiting Kepler-396 (KOI-2672) and explore two possible cases of a third planet in that system that could explain the measured transit times. We update the ephemerides and mass constraints where possible at KOI-70 (Kepler-20), KOI-82 (Kepler-102), KOI-94 (Kepler-89), KOI-137 (Kepler-18), KOI-244 (Kepler-25), KOI-245 (Kepler-37), KOI-282 (Kepler-130), KOI-377 (Kepler-9), KOI-620 (Kepler-51), KOI-806 (Kepler-30), KOI-1353 (Kepler-289) and KOI-1783 (Kepler-1662).
