Variable stars detection in the field of open cluster NGC 188
Fang-Fang Song, Hu-Biao Niu, Ali Esamdin +2
This work presents the charge-coupled device (CCD) photometric survey of the old open cluster NGC 188. Time-series V-band photometric observations were conducted for ten nights in…
Binary open clusters in the Gaia data
Fangfang Song, Ali Esamdin, Qingshun Hu +1
Context. Observations indicate that the fraction of potential binary star clusters in the Milky Way is either the same or lower than that of the Magellanic Clouds. The unprecedente…
Investigating Variable Stars in the Open Cluster NGC 1912 and Its Surrounding Field
Chunyan Li, Ali Esamdin, Yu Zhang +6
In this work, we studied the variable stars in the open cluster NGC 1912 based on the photometric observations and DR2 data. More than 3600 CCD frames in B, V, R filters wer…
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.…
Pulsations of the High-Amplitude Scuti Star YZ Bootis
Taozhi Yang, Ali Esamdin, Jianning Fu +5
We present a study on the pulsations of the high-amplitude Scuti star YZ Boo based on photometric observations in Johnson and bands with both the Nanshan 1-m telescope…
A study of variable stars in the open cluster NGC 1582 and its surrounding field
Fang-Fang Song, Ali Esamdin, Lu Ma +4
This paper presents the Charge-Coupled Device time-series photometric observations of the open cluster NGC 1582 and its surrounding field with Johnson B, V and R filters by using N…
