The O'Connell effect—the presence of unequal maxima in eclipsing binaries—remains an
unsolved riddle in the study of close binary systems. The Kepler space telescope produced …

Multi-band photometric observations and period investigations of the total eclipsing binary

Asymmetries between the two maxima of the light curves of contact binaries, known as the
O'Connell effect, have been identified using the All Sky Automated Survey, All-Sky …

The phenomenological parameters of eclipsing binary stars, which are the prototypes of the
EA, EB and EW systems are determined using the expert complex of computer programs …

We present a by-product of our long term photometric monitoring of cataclysmic variables.
2MASS J18024395+ 4003309= VSX J180243. 9+ 400331 was discovered in the field of the …

Using ground-based telescopes, the multi-color photometric observations of the contact
binary EF Boo were obtained in 2020, 2023, and 2024. Combining these with 7-sectors of …

The dependence of the test function on the phenomenological parameters used in the"
NAV"(" New Algol Variable") algorithm (Andronov, 2012Ap..... 55.. 536A) is studied. Due to a …

We present an updated catalog of 4680 northern eclipsing binaries (EBs) with Algol-type
light-curve (LC) morphology (ie, with well-defined beginnings and ends of primary and …
