摘要

我们介绍了韩国秘阳阿里郎天文台(MAAO)的 0.7 米望远镜系统。通过系统集成和调度程序,0.7 米望远镜系统可在夜间完全由机器人操作,无需人工干预。利用 0.7 米望远镜系统,我们通过观测标准恒星获得了大气消光系数和零点星等。结果发现,大气消光系数适中,但有时也会因天气条件而增加。在天气晴朗的条件下,对于一个总综合时间为 10 分钟的点光源,测得的 5σ 极限星等可低至 BVRI = 19.4-19.6 AB 等,这表明其性能与在类似规格和天空条件下运行的其他观测设施相当。我们预计,新建立的亚洲天文观测台 0.7 米望远镜系统将为天文学观测研究做出重大贡献。特别是该系统具有机器人观测能力,尽管其主要职责是供公众观赏,但可广泛用于瞬变的时间序列观测。

The Robotic MAAO 0.7 m Telescope System: Performance and Standard Photometric System
We introduce a 0.7 m telescope system at the Miryang Arirang Astronomical Observatory (MAAO), a public observatory in Miryang, Korea. System integration and a scheduling program enable the 0.7 m telescope system to operate completely robotically during nighttime, eliminating the need for human intervention. Using the 0.7 m telescope system, we obtain atmospheric extinction coefficients and the zero-point magnitudes by observing standard stars. As a result, we find that atmospheric extinctions are moderate but they can sometimes increase depending on the weather conditions. The measured 5σ limiting magnitudes reach down to BVRI = 19.4–19.6 AB mag for a point source with a total integrated time of 10 minutes under clear weather conditions, demonstrating comparable performance with other observational facilities operating under similar specifications and sky conditions. We expect that the newly established MAAO 0.7 m telescope system will contribute significantly to the observational studies of astronomy. Particularly, with its capability for robotic observations, this system, although its primary duty is for public viewing, can be extensively used for the time-series observation of transients.

期刊介绍: The Publications of the Astronomical Society of the Pacific (PASP), the technical journal of the Astronomical Society of the Pacific (ASP), has been published regularly since 1889, and is an integral part of the ASP''s mission to advance the science of astronomy and disseminate astronomical information. The journal provides an outlet for astronomical results of a scientific nature and serves to keep readers in touch with current astronomical research. It contains refereed research and instrumentation articles, invited and contributed reviews, tutorials, and dissertation summaries.
