SiTian项目
The SiTian project
摘要：
四天是一个雄心勃勃的地基全天空光学监测项目，由中国科学院开发。这个概念是一个由数十个1米级望远镜组成的综合网络，部分部署在中国，部分部署在世界各地的其他地点。主要的科学目标是在不到1天的时间尺度上探测、识别和监测光学瞬变（如引力波事件、快速射电暴、超新星）;思天还将为活动星系核、类星体、变星、行星、小行星和微透镜事件的研究提供宝贵的数据。为了实现这些目标，“四田”将每30分钟扫描至少10,000平方度的天空，直到探测极限为$V \approx 21$。扫描将在3个光学波段同时产生光变曲线。此外，四田将包括至少三个4米望远镜，专门用于最有趣的目标的后续光谱学。我们计划到2030年完成72台望远镜的安装，并在2032年开始全面的科学运作。
英文摘要：
SiTian is an ambitious ground-based all-sky optical monitoring project, developed by the Chinese Academy of Sciences. The concept is an integrated network of dozens of 1-m-class telescopes deployed partly in China and partly at various other sites around the world. The main science goals are the detection, identification and monitoring of optical transients (such as gravitational wave events, fast radio bursts, supernovae) on the largely unknown timescales of less than 1 day; SiTian will also provide a treasure trove of data for studies of AGN, quasars, variable stars, planets, asteroids, and microlensing events. To achieve those goals, SiTian will scan at least 10,000 square deg of sky every 30 min, down to a detection limit of $V \approx 21$ mag. The scans will produce simultaneous light-curves in 3 optical bands. In addition, SiTian will include at least three 4-m telescopes specifically allocated for follow-up spectroscopy of the most interesting targets. We plan to complete the installation of 72 telescopes by 2030 and start full scientific operations in 2032.
