An analysis of the fragmentation of observing time at the Muztagh-ata site
Gu Wen-bo, Xu Jing, Feng Guo-jie +5
Cloud cover plays a pivotal role in assessing observational conditions for astronomical site-testing. Except for the fraction of observing time, its fragmentation also wields a sig…
Photometric calibration of the Stellar Abundance and Galactic Evolution Survey (SAGES): Nanshan One-meter Wide-field Telescope g, r, and i band imaging data
Kai Xiao, Haibo Yuan, Bowen Huang +16
In this paper, a total of approximately 2.6 million dwarfs were constructed as standard stars, with an accuracy of about 0.01-0.02 mag for each band, by combining spectroscopic dat…
The Stellar Abundances and Galactic Evolution Survey (SAGES) -- -- I. General Description and the First Data Release (DR1)
Zhou Fan, Gang Zhao, Wei Wang +35
The Stellar Abundances and Galactic Evolution Survey (SAGES) of the northern sky is a specifically-designed multi-band photometric survey aiming to provide reliable stellar paramet…
Site-testing at the Muztagh-ata Site.V. Nighttime Cloud Amount during the Last Five Years
Jing Xu, Guo-jie Feng, Guang-xin Pu +12
The clarity of nights is the major factor that should be carefully considered for optical/infrared astronomical observatories in site-testing campaigns. Cloud coverage is directly…
KIC 10417986: Spectroscopic confirmation of the nature of the binary system with a δ Scuti component
Guo-Jie Feng, Ali Esamdin, Jian-Ning Fu +9
KIC 10417986 is a short orbital period (0.0737 d) ellipsoidal variable star with a δ Scuti and γ Doradus hybrid pulsations component discovered by Kepler. The ground-based spectros…
The Wide-field Photometric System of the Nanshan One-meter Telescope
Chunhai Bai, Guojie Feng, Xuan Zhang +9
The Nanshan One-meter Wide-field Telescope (NOWT) is a prime focus system located at Nanshan Station of Xinjiang Astronomical Observatories (XAO). The field of view(FOV) was design…
Site-testing at Muztagh-ata site I: Ground Meteorology and Sky Brightness
Jing Xu, Ali Esamdin, Jin-xin Hao +28
Site-testing is crucial for achieving the goal of scientific research and analysis of meteorological and optical observing conditions is one of the basic tasks of it. As one of thr…
Site-testing at Muztagh-ata site II: Seeing statistics
Jing Xu, Ali Esamdin, Jin-xin Hao +28
In this article, we present a detailed analysis of the statistical properties of seeing for the Muztagh-ata site which is the candidate site for hosting future Chinese Large Optica…

Lu Feng, Jin-Xin Hao, Zi-Huang Cao +35
The Large Optical/infrared Telescope (LOT) is a ground-based 12m diameter optical/infrared telescope which is proposed to be built in the western part of China in the next decade.…
Pulsations of the SX Phe Star BL Camelopardalis
Peng Zong, Ali Esamdin, Jian Ning Fu +6
We carried out photometric observations of the SX Phe star BL Cam in 2014, 2017 and 2018 using Nanshan 1-m telescope. In addition to the dominated frequency of 25.5790(3) cd…
A Weak Modulation Effect Detected in the Light Curves of KIC 5950759: Intrinsic or Instrumental Effect?
Taozhi Yang, A. Esamdin, Fangfang Song +8
In this paper, the high-precision light curves of target KIC 5950759 are analyzed. The Fourier analysis of the long cadence light curve reveals 3 independent frequencies.…
