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…
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…
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 Properties and Evolutions of Starspots on Three Detached Eclipsing Binaries in the LAMOST-Kepler survey
Jiaxin Wang, Jianning Fu, Weikai Zong +4
The spotted detached eclipsing binary (DEB) offers insights into starspots on the binary. Three spotted DEBs, KIC 8097825, KIC 6859813, and KIC 5527172, which were observed by the…
Spot and Facula Activity Variations of the Eccentric Detached Eclipsing Binary KIC 8098300 Based on the Time-series Orbital Solutions
Hubiao Niu, Jianning Fu, Jiaxin Wang +1
The LAMOST spectra and light curves are combined to investigate the detached eclipsing binary KIC 8098300, which shows the O'Connell effect caused by spot/facula modu…
Searching for orbital decay in a heartbeat star system KIC 3766353
Jian-Wen Ou, Cong Yu, Chen Jiang +2
Theory suggests that the orbits of a large fraction of binary systems, including planet-star binary systems, shrink by few orders of magnitude after formation. But so far, only one…
Phase II of the LAMOST-Kepler/K2 survey. I. Time series of medium-resolution spectroscopic observations
Weikai Zong, Jian-Ning Fu, Peter De Cat +20
Phase \RNum{2} of the LAMOST-{\sl Kepler/K}2 survey (LK-MRS), initiated in 2018, aims at collecting medium-resolution spectra (; hereafter MRS) for more than s…
An optical and X-ray study of the contact binary, BH Cassiopeiae
Junhui Liu, Ali Esamdin, Yu Zhang +10
We present the revised and high quality CCD time series observations in 2017 and 2018 of the W UMa-type contact binary BH~Cas. The combination of our new determinations of minimum…
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…
Precise determination of stellar parameters of the ZZ Ceti and DAZ white dwarf GD 133 through asteroseismology
J. -N. Fu, G. Vauclair, J. Su +15
An increasing number of white dwarf stars show atmospheric chemical composition polluted by heavy elements accreted from debris disk material. The existence of such debris disks st…
Frequent flare events on the short-period M-type eclipsing binary BX Tri
ChangQing Luo, XiaoBin. Zhang, Kun Wang +8
We present long-term, multi-color photometric monitoring and spectroscopic observations of the short-period M-type eclipsing binary BX Tri. Six flare events were recorded in 4 year…
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.…
Star-disk interactions in multi-band photometric monitoring of the classical T Tauri star GI Tau
Zhen Guo, Gregory J. Herczeg, Jessy Jose +16
The variability of young stellar objects is mostly driven by star-disk interactions. In long-term photometric monitoring of the accreting T Tauri star GI Tau, we detect extinction…
