摘要:

下一代凌日巡天计划(NGTS)是一项新的地基巡天计划,旨在寻找正在凌日的海王星和超级地球。通过覆盖至少16倍于开普勒的天空面积,我们将发现恒星周围的小行星,它们足够明亮,可以确认径向速度,确定质量和大气特征。NGTS仪器将由12个独立指向的20厘米望远镜阵列组成,配有红敏CCD相机。它将在ESO Paranal天文台建造,从而受益于最佳的光度条件以及与VLT和E-ELT的后续协同作用。我们的设计已经通过两个原型仪器的操作进行了验证,展示了亚mmag光度精度的白噪声特性。详细的模拟显示,大约30颗明亮的超级地球和多达200颗海王星可能被发现。我们的科学行动将于2014年开始。

英文摘要:

The Next Generation Transit Survey (NGTS) is a new ground-based sky survey designed to find transiting Neptunes and super-Earths. By covering at least sixteen times the sky area of Kepler we will find small planets around stars that are sufficiently bright for radial velocity confirmation, mass determination and atmospheric characterisation. The NGTS instrument will consist of an array of twelve independently pointed 20cm telescopes fitted with red-sensitive CCD cameras. It will be constructed at the ESO Paranal Observatory, thereby benefiting from the very best photometric conditions as well as follow up synergy with the VLT and E-ELT. Our design has been verified through the operation of two prototype instruments, demonstrating white noise characteristics to sub-mmag photometric precision. Detailed simulations show that about thirty bright super-Earths and up to two hundred Neptunes could be discovered. Our science operations are due to begin in 2014.
