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 relationships between the orbital period and some parameters of W Ursae Majoris (W
UMa)-type systems are presented in this study. To investigate the relationships, we …

Period cut-off and period–colour relation are two special characters of W UMa-type contact
binaries. In the past, many authors noted these two properties, however, a comprehensive …

We present a detailed light-curve analysis of publicly available V-band observations of 62
binary stars, mostly contact binaries, obtained by the All Sky Automated Survey (ASAS)-3 …

We present results of the modelling of multicolour light curves of 10 contact binary systems:
V376 And, V523 Cas, CC Com, BX Dra, FG Hya, UZ Leo, XY Leo, AM Leo, EX Leo and RT …

Secondary components of W UMa-type contact binaries (CBs) have many special
properties, two of them are excess in radius and luminosity. In order to make these …

From the 100-day TESS observations, we comprehensively studied the variations of the light
curve and orbital period for EE Cet. It is found that an 83.2-day oscillation occurs in the …

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 …

We performed photometric and spectroscopic studies on four W Ursae Majoris eclipsing
binaries (V384 Ser, AQ Psc, V480 Gem and 2MASS J07095549+ 3643564). The binaries …

High-precision light curves were extracted from TESScut images. Together with APOGEE
and LAMOST medium-resolution spectra, a joint study was made for six early K-type contact …
