摘要 下一代凌日巡天（NGTS）是一项针对凌日系外行星的新型地面巡天。我们的主要目标是找到第一个具有统计意义的海王星和超级地球样本，这些样本的亮度足以确认径向速度。通过测量精确的质量和半径，我们将限制跨越气态巨行星和类地行星之间过渡的行星的整体成分和内部结构。我们最亮的系外行星也适合使用 VLT、JWST 和 E-ELT 等大型设施进行大气特征分析。 NGTS 建设于 2013 年 6 月开始，调查预计于 2014 年开始。
Abstract The Next Generation Transit Survey (NGTS) is a new ground-based survey for transiting exoplanets. Our primary goal is to find the first statistically-significant sample of Neptunes and super-Earths that are bright enough for radial velocity confirmation. By measuring precise masses and radii we will constrain the bulk composition and internal structure of planets that span the transition between the gas giants and terrestrial planets. Our brightest exoplanets will also be suitable for atmospheric characterisation with large facilities such as the VLT, JWST and the E-ELT. NGTS construction began in June 2013, and the survey is due to commence in 2014.
