The catalogue of 361 galactic contact binaries is presented. Enlisted contact binaries are divided into five groups according to the type and quality of the available...

This catalogue contains information about 44 binaries with known photometric orbit elements and unknown spectroscopic one. Cone search capability for table V/118/catalog (Catalog)

The catalog contains two parts: 96 well known semidetached eclipsing binaries with known photometric and spectroscopic orbits (table1.dat), and 136 semidetached eclipsing...

We present the results of the reduction of our photometric and spectroscopic observations for the eclipsing binary SZ Cam performed with the telescopes at the Astronomical...

The results of a UBVR photometry observations and light curve analysis are presented for eclipsing binary, BZ Mon.

The results of a UBVR photometry observations are presented for eclipsing variable EQ Ori. The binary was observed 1988 with the 1-m telescope at Maidanak Observatory (Uzbekistan).

New photoelectric UBVRI observations of the eclipsing variable V1016 Ori have been obtained with the AZT-11 telescope at Crimean Astrophysical Observatory and with the Zeiss-600...

New uvby-{beta} photometry of the unique binary RY Sct is reported. The results were interpreted using the light-curve synthesis method.

The results of a UBVR photometry observations are presented for eclipsing binaries KV Cyg, V435 Cyg and V699 Cyg. Each binary was observed 1989/91 with the 60 cm telescopes at...

The results of a UBVR photometry observations are presented for eclipsing binary V1481 Cyg in the open cluster NGC 7128. The binary was observed between 1993 and 1995 with the...

Photoelectric UBVR photometry of 2 eclipsing variables are presented. Each binary was observed between 1989 and 1995 with the 60 cm telescopes at the Maidanak Observatory...

We performed photometric, spectroscopic and orbital period investigations of ASASSN-V J015428.67+204247.2 (hereafter, J015428) for the first time. The light curves of VRI bands...

Photometric analysis and spectroscopic study of the long-period low-mass-ratio deep-contact binary KN Per were performed. The light curves of the BV(RI)c band were from the...

New CCD photometry for the eclipsing binary EH Cnc was made from 2009 to 2011, and five new eclipsing times are presented. Through using the updated Wilson-Devinney code, we...

We present the results of new CCD photometry for the contact binary BX Peg, made during three successive months beginning on 2008 September. As do historical light curves, our...

The regions around the celestial poles offer the ability to find and characterize long-term variables from ground-based observatories. We used multi-year Evryscope data to...

The Evryscope is a telescope array designed to open a new parameter space in optical astronomy, detecting short-timescale events across extremely large sky areas simultaneously....

We present UBV photoelectric observations of the W UMa star BF Pav obtained between 1987 and 1993. A time-of-minimum study allows detection of a likely period increase of about...

We present BV light-curve synthetic analyses of three short-period contact (W UMa) binaries: HY Pavonis (P=~0.35days), AW Virginis (P=~0.35days), and BP Velorum (P=~0.26days)....

Continuing the project described by Kato et al. (2009PASJ...61S.395K), we collected times of superhump maxima for 127 SU UMa-type dwarf novae observed mainly during the...
