论文摘要
由于相对较短的观察序列和这些任务的寿命短，因此即使在太空望远镜的世纪中，还要在太空望远镜的世纪中确定长期黯然失色的二进制文件仍然是一个挑战。过渡系外行星调查卫星（TESS）空间望远镜是补充以前的基于空间观测值的合适工具。在本文中，我们报告了通过Corot和Tess太空望远镜测量的Eclipse Piming Piming变化（ETV）分析的第一个结果。在1428个EB候选人中，我们发现了4个新的潜在三重候选者，为此，通过众所周知的轻轨效应（LTTE）对ETV进行了分析和拟合。其中一个显示了其折叠光曲线的显着相移，这需要额外的注意。在本文中，我们还提出了一些其他系统，这些系统显示出大量的ETV信号，这些系统可以通过传质或APSidal运动来解释。
Identifying long-period eclipsing binaries with space-based photometry is still a challenge even in the century of space telescopes due to the relatively short observation sequences and short lifetime of these missions. The Transiting Exoplanet Survey Satellite (TESS) space telescope is an appropriate tool to supplement previous space-based observations. In this paper we report the first results of the eclipse timing variation (ETV) analyses of eclipsing binaries (EBs) measured by CoRoT and TESS space telescopes. Among the 1428 EB candidates we found 4 new potential triple candidates, for which ETV was analysed and fitted by the well-known light-travel-time effect (LTTE). One of them shows significant phase shift in its folded light curve which required extra care. In this paper we also present some other systems showing significant ETV signals that could be explained by mass transfer or apsidal motion.
