The extraneous eclipses on binary light curves: KIC 5255552, KIC 10091110, and KIC 11495766
J. Zhang, S. B. Qian, S. M. Wang +3
Aims. We aim to find more eclipsing multiple systems and obtain their parameters, thus increasing our understanding of multiple systems. Methods. The extraneous eclipses on the \te…
Photometric and period investigation of the late F-type overcontact binary II UMa
X. Zhou, S. -B. Qian, J. Zhang +2
II UMa is a late F-type (F5) contact binary with a close-in tertiary and a distant visual companion. According to the four-color ( ) light curves' solutions of II…
The first photometric analysis of the overcontact binary MQ UMa with an additional component
X. Zhou, S. -B. Qian, W. -P. Liao +3
The first V Rc Ic bands light curves of MQ UMa are presented and analyzed using the Wilson-Devinney (W-D) program. It is discovered that MQ UMa is an A-subtype contact binary with…
Photometric Investigation of the Total-Eclipsing Contact Binary V12 in the Intermediate-age Open Cluster NGC 7789
S. -B. Qian, A. Essam, J. -J. Wang +3
NGC 7789 is an intermediate-age open cluster with an age that is similar to the mean age of contact binary stars. V12 is a bright UMa-type binary star with an orbital period of 0.3…
Optical flares and flaring oscillations on the M-type eclipsing binary CU Cnc
Qian S. -B., J. Zhang, L. -Y. Zhu +7
We report here the discovery of an optical flare observed in R band from the red-dwarf eclipsing binary CU Cnc whose component stars are at the upper boundary of full convection (M…
CCD Photometric Study of the Contact Binary TX Cnc in the Young Open Cluster NGC 2632
Liu Liang, Qian Shengbang, BOONRUCKSAR Soonthornthum +3
TX Cnc is a member of the young open cluster NGC 2632. In the present paper, four CCD epochs of light minimum and a complete V light curve of TX Cnc are presented. A period investi…
High Fill-Out, Extreme Mass Ratio Overcontact Binary Systems. X. The new discovered binary XY Leonis Minoris
S. -B. Qian, L. Liu, L. -Y. Zhu +3
The new discovered short-period close binary star, XY LMi, was monitored photometrically since 2006. It is shown that the light curves are typical EW-type and show complete eclipse…
