论文摘要
我们提出了即将到来的Nix Imager的最佳调查策略，这是将安装在非常大型望远镜（VLT）上的ERIS仪器的一部分。我们将使用自定义的2.2微米K-Peak滤波器来优化未来大规模直接成像调查的效率，旨在检测附近恒星周围的棕色矮人和巨型行星。我们使用以前的大规模成像调查（主要是Sphere Shine和Gemini Gpies）的结果来告知我们对目标的选择，并改善了行星种群分布。我们提出了四种可能的方法，以优化检测最高收益率的调查目标列表：i）针对异常运动趋势的对象，ii）对Spearsh Shine和Gemini Gpies III的密集田地的后续调查，对附近的星形形成区域进行调查，并针对附近发现的年轻人的新发现的成员。我们还将NIX的预测性能与其他最先进的直接成像仪器进行了比较。
We present optimal survey strategies for the upcoming NIX imager, part of the ERIS instrument to be installed on the Very Large Telescope (VLT). We will use a custom 2.2 micron K-peak filter to optimise the efficiency of a future large-scale direct imaging survey, aiming to detect brown dwarfs and giant planets around nearby stars. We use the results of previous large scale imaging surveys (primarily SPHERE SHINE and Gemini GPIES) to inform our choice of targets, as well as improved planet population distributions. We present four possible approaches to optimise survey target lists for the highest yield of detections: i) targeting objects with anomalous proper motion trends, ii) a follow-up survey of dense fields from SPHERE SHINE and Gemini GPIES iii) surveying nearby star-forming regions and iv) targeting newly discovered members of nearby young moving groups. We also compare the predicted performance of NIX to other state-of-the-art direct imaging instruments.
