Extending the Next Generation Transit Survey into the infrared

我们将购买一台近红外摄像机，用于下一代凌日巡天。下一代凌日巡天是一个由STFC支持的设施，由12个20厘米镜面望远镜组成，配备了优化的520-890纳米波长范围内的相机。NGTS进行了广泛的系外行星调查，并有针对性地观察了来自美国宇航局TESS任务的单次凌日事件、星团和明亮恒星。NGTS由莱斯特大学、华威大学、贝尔法斯特女王大学、剑桥大学、日内瓦大学和德国劳姆法赫特中心（DLR）组成的财团运营。总部设在英国的财团都以机构资金支持该设施，并通过助学金和奖学金获得STFC科学支持，以利用NGTS的科学成果。所有的数据最终都会公开，并由欧洲南方天文台存档。我们还通过Zooniverse主办的行星猎人NGTS公民科学计划公开了我们的数据。有了这个相机，我们不仅可以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特征。对于最亮的目标，我们将能够同时获得标准NGTS设置的光学光曲线，以及近红外光曲线，使我们能够确定有关过境物体及其母星的更多信息。

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.
