我们在这里介绍SPECULOOS，一个新的系外行星过境搜索，基于1 m级机器人望远镜网络，目标是~1200个超冷（光谱类型M7及以后）矮星，在红外线（K-mag ≤ 12.5）中足够明亮，可能使气候温和的类地行星的大气特征与下一代设施，如詹姆斯韦伯太空望远镜。该项目的最终目标是揭示最低质量恒星和褐矮星周围温带类地行星的频率，探测其整体成分、大气和表面条件的多样性，并评估其潜在的可居住性。
We present here SPECULOOS, a new exoplanet transit search based on a network of 1m-class robotic telescopes targeting the ~1200 ultracool (spectral type M7 and later) dwarfs bright enough in the infrared (K-mag ≤ 12.5) to possibly enable the atmospheric characterization of temperate terrestrial planets with next-generation facilities like the James Webb Space Telescope. The ultimate goals of the project are to reveal the frequency of temperate terrestrial planets around the lowest-mass stars and brown dwarfs, to probe the diversity of their bulk compositions, atmospheres and surface conditions, and to assess their potential habitability.
