We will purchase a near-infrared camera for use on the Next Generation Transit Survey. The Next Generation Transit Survey is an STFC supported facility consisting of 12 20cm mirror telescopes fitted with cameras optimised for operation in the 520-890 nm wavelength range. NGTS has conducted wide field exoplanet surveys, and targeted observations of single transit events from NASA's TESS mission, star clusters and bright stars. NGTS is operated by a consortium consisting of the University of Leicester, University of Warwick, Queen's University Belfast, University of Cambridge, University of Geneva and the Deutsches Zentrum fuer Luft- in Raumfahrt e.V. (DLR). The UK based consortium all supported the facility with institutional funding and have received STFC science support via Grants and Studentships to exploit the scientific results from NGTS. All data eventually becomes public and is archived by the European Southern Observatory. We also make our data public via the PlanetHunters NGTS citizen science programme hosted by Zooniverse.With this camera we will not only be able to discover new planets around other stars, but also the so called failed stars: brown dwarfs and extremely low mass eclipsing binaries but also contribute towards their characterisation. For the brightest targets we will be able to get simultaneous light curves in the optical with the standard NGTS setup, and in the near-infrared allowing us to determine more information about the transiting object and its parent star.

我们将购买一台近红外摄像机，用于下一代交通调查。下一代凌日巡天是STFC支持的设施，由12个20厘米镜面望远镜组成，配有优化的相机，可在520-890 nm波长范围内运行。NGTS进行了广泛的系外行星调查，并有针对性地观测了来自NASA TESS使命、星星团和明亮恒星的单次凌日事件。NGTS由一个财团运营，该财团由莱斯特大学、沃里克大学、贝尔法斯特女王大学、剑桥大学、日内瓦大学和德国航空航天中心组成。总部设在英国的联合体都支持该设施与机构的资金，并已收到STFC的科学支持，通过赠款和助学金，利用科学成果从NGTS。所有数据最终都会公开，并由欧洲南方天文台存档。我们还通过由Zooniverse主办的PlanetHunters NGTS公民科学计划公开我们的数据。有了这台相机，我们不仅能够发现其他恒星周围的新行星，还可以发现所谓的失败恒星：褐矮星和极低质量的食双星，而且还有助于它们的表征。对于最亮的目标，我们将能够在标准NGTS设置的光学中获得同步的光变曲线，并且在近红外中，使我们能够确定关于凌日物体及其母星星的更多信息。
