This project involves the usage of new scientific CMOS (sCMOS) cameras produced by Andor for high-precision astronomical photometry. sCMOS cameras have recently been tested under laboratory conditions, and the results are extremely promising for astronomical purposes (Karpov et al., 2019). The Next Generation Transit Survey (NGTS; Wheatley et al., 2018) facility is a set of 12 identical 20cm telescopes situated at Paranal Observatory in Chile (one of the best sites in the world). NGTS surveys bright stars with high precision photometry in order to detect transiting "exoplanets" - planets orbiting other stars (e.g. NGTS-1b; Bayliss et al., 2018). We propose to couple a new generation Andor sCMOS detector to an NGTS telescope. The primary goal is, for the first time ever, to obtain high precision photometry of bright stars to detect transiting exoplanets. We will run this experiment alongside another NGTS telescope with an existing CCD camera for comparative purposes. sCMOS detectors have yet to be embraced by the astronomical community, however peer-reviewed publications of in-depth and meaningful on-sky assessments are the key to unlocking such acceptance.

该项目涉及使用Andor为高精​​度天文学光度法制作的新科学CMO（SCMOS）摄像机的使用。 SCMOS摄像机最近在实验室条件下进行了测试，结果对于天文学目的来说是极为有希望的（Karpov等，2019）。下一代运输调查（NGTS; Wheatley等，2018）设施是位于智利Paranal天文台（世界上最好的景点之一）的12个相同的20厘米望远镜。 NGTS以高精度光度法来调查明亮的恒星，以检测绕过其他恒星的跨行星（例如NGTS -1B； Bayliss等，2018）。我们建议将新一代的Andor Scmos检测器与NGTS望远镜相结合。主要目标是有史以来首次获得明亮恒星的高精度光度法以检测过境的系外行星。我们将与另一台NGTS望远镜一起运行此实验，并使用现有的CCD摄像头进行比较。天文学群落尚未接受SCMOS探测器，但是对深度和有意义的对天内评估的同行评审出版物是解锁这种接受的关键。
