High precision CCD observations of six totally eclipsing contact binaries were presented
and analyzed. It is found that only one target is an A-type contact binary (V429 Cam), while …

New CCD photometric light curves in the B and V bands of the neglected W UMa–type
eclipsing variable star CU Tauri are presented. The O'Connell effect in the V light curve …

CCD photometric light curves in the B and V bands obtained in 2001 and in the V band
obtained in 2002 of AH Cnc in the old open cluster M67 are presented. It is shown that AH …

CCD photometric observations of AD Cancri obtained from 2000 March 7 to 2004 December
20 are presented. Variations of the light levels at the primary minimum and both maxima are …

The first photometric solutions of the very short period (VSP) close binary DD Comae
Berenices (P= 0 fd 26920811) based on our new complete (IR) C light curves are derived by …

We investigated the statistical properties of both cool and hot starspots in eclipsing binary
stars. The starspot and binary parameters for contact and semi-detached systems were …

ABSTRACT CCD photometric observations of the newly discovered close binary, EM
Piscium, obtained from 2006 December 4 to 2008 January 7, are presented. The light curves …

We construct a sample of 9380 contact binaries (W UMa systems) by using the Catalina
Real-Time Transient Survey Variables Sources Catalogue. By measuring brightness change …

BV photometric light curves of the eclipsing binary IK Per were obtained during three nights
in 2002 December. The photometric elements were computed using the Wilson-Devinney …

New photometric observations and their investigation of the W UMa-type binary, BI CVn, are
presented. The variations of the orbital period were analyzed based on 12 new determined …
