论文摘要
我们报告了传播系外行星的后续观察，这些观察结果在其过境时间内具有很大的不确定性（> 10分钟），或者三年多未观察到。一个完全机器人的地面望远镜网络，公民天文学家的观察以及苔丝的数据已被用于研究八个行星，完善了它们的占地和轨道数据。这样的后续观察是确保即将到来的地面和空间望远镜的准确过境时间的关键，这些望远镜可能试图表征这些行星的大气。我们发现与所有行星的预期过境时间偏离，过渡发生在1个Sigma不确定性以外的七个行星。使用新获得的观测值，我们随后将其周期完善，并将当前预测的埃菲米利不确定性减少到0.28-4.01分钟。这项工作的很大一部分是由伦敦两所高中的学生完成的，这是年轻的Twinkle学生（Orbyts）计划的原始研究的一部分。
We report follow-up observations of transiting exoplanets that have either large uncertainties (>10 minutes) in their transit times or have not been observed for over three years. A fully robotic ground-based telescope network, observations from citizen astronomers and data from TESS have been used to study eight planets, refining their ephemeris and orbital data. Such follow-up observations are key for ensuring accurate transit times for upcoming ground and space-based telescopes which may seek to characterise the atmospheres of these planets. We find deviations from the expected transit time for all planets, with transits occurring outside the 1 sigma uncertainties for seven planets. Using the newly acquired observations, we subsequently refine their periods and reduce the current predicted ephemeris uncertainties to 0.28 - 4.01 minutes. A significant portion of this work has been completed by students at two high schools in London as part of the Original Research By Young Twinkle Students (ORBYTS) programme.
