BVRI light curves of GR Boo
We present BVRI light curves with complete phase coverage for the short-period (p=0.377day) eclipsing binary star GR Boo. We carried out the observations using the SARA 90cm... -
V2480 Cyg V and R light curves
We present the photometric analysis of the detached eclipsing binary V2480 Cyg. After taking the photometric data, the light curve was analyzed in PHOEBE software, which uses... -
LY And photometric followup
We present a low-dispersion spectrum and two sets of CCD photometric light curves of the eclipsing binary LY And for the first time. The spectrum of LY And was classified as G2.... -
AS CrB BVRI light curves
The first high-precision BVRI light curves of the eclipsing binary AS CrB were presented and were analyzed by the 2015 version of the W-D code. It is found that AS CrB is an... -
OQ Dra V light curve
The present study is an analysis of V-band CCD observations of new W UMa contact binary OQ Dra. To carry out the analysis, Primary and secondary minimum were obtained and new... -
V1044 Her VR differential photometry
We present new CCD photometric observations of V1044 Her obtained on May 22, 23 and 24, 2015. From our data, we derived five new light curve minimum times. Combining our new... -
AQ Boo VRI differential light curves
We obtained the first VRI CCD light curves of the short-period contact eclipsing binary AQ Boo, which was observed on March 22 and April 19 in 2014 at Xinglong station of... -
Time of minima of BX Peg
We presented BVRcIc light curves of BX Peg obtained by the Weihai Observatory 1.0m telescope of Shandong University. The W-D code was used to analyze the four color light... -
VIr light curves of GK Aqr
We made the first VRI CCD light curves of the short-period contact eclipsing binary GK Aqr, which was observed on October 5 and 8, 2013 at Xinglong station of National... -
ZZ Cyg times of minima
We present new photometry of the eclipsing binary ZZ Cyg. From all accumulated eclipsing times, we constructed the (O-C) curve, which can be described by a downward parabola... -
V873 Per BVR light curves
We present a photometric study of a weak-contact binary V873 Per. New observations in BVR filter bands showed asymmetric light curves to be a negative type of the O'Connell... -
V441 Lac VRI light curves
We present the first multi-color VRI CCD light curves of a short-period eclipsing binary star v441 Lac in this paper. We obtained our light curves on Oct. 4 and 8, 2013 at... -
Time minima of EP Aur
We present new observations for the eclipsing binary EP Aurigae, which were performed by using three small telescopes in China from 2003 December to 2014 January. With the... -
Light curves of 8 Algol-type systems
Analyzing available photometry from the Super WASP and other databases, we performed the very first light curve analysis of eight eclipsing binary systems V537 And, GS Boo, AM... -
BVRcIc light curves of LU Lac
LU Lac is a neglected W UMa binary star in photometric investigations. In this paper, we present BVRI CCD photometric light curves obtained on one night in 2012. The first... -
V729 Cyg UBVRI light curves
We present multicolor photometry of the massive interacting close binary system V729 Cyg. The light variations of V729 Cyg were observed in the Bessel U, B, V, R and I bands... -
BVR light curves of V1191 Cyg
We present the analysis of photometric and spectroscopic variation, and orbital period study of the late-type contact binary system V1191 Cyg. The system is found to be a... -
Eclipsing times of BE Cep
New photometry for the eclipsing binary BE Cephei was performed from 2008 to 2011. -
GO Cyg BV light curves
In this study, we present long term photometric variations of the close binary system GO Cyg. Modelling of the system shows that the primary is filling Roche lobe and the... -
PP Lac TESS light curves
In this study we aim to reveal the starspot behaviour in the contact binary PP Lac, using the clues from the eclipse timing variation (ETV) nature of the system, obtained from...
