论文摘要
Sitian是一个雄心勃勃的地面全套光学监测项目，由中国科学院开发。该概念是一个由数十个1-M级望远镜组成的集成网络，部分部署在中国，部分是在世界各地的其他各个地点。主要的科学目标是对光学瞬变的检测，鉴定和监测（例如重力波事件，快速无线电爆发，超新星）在很大程度上未知的时间尺度小于1天； Sitian还将为AGN，类星体，可变恒星，行星，小行星和微透镜事件的研究提供宝藏数据。为了实现这些目标，Sitian将每30分钟至少扫描10,000平方公段的天空，降至$ V \ $ V \ 21美元的检测极限。扫描将在3个光条带中产生同时的光曲线。此外，Sitian将至少包括三个4-M望远镜，专门分配了最有趣的目标的随访光谱。我们计划到2030年完成72台望远镜的安装，并于2032年开始全面的科学操作。
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.
