A catalogue of (411) Algol-type (semi-detached) binary stars is presented in the form of five separate tables of information. The catalogue has developed from an earlier version...

Between 1996 and 2003 we obtained 226 high resolution spectra of 16 stars in the field of the young open cluster NGC 6913, to constrain its main properties and study its...

In a first report on the results of a multi-site campaign in 2001 of photometric and spectroscopic observations of the active semi-detached Algol-type system RZ Cas, we...

New and complete UBV light curves and times of minimum are presented for the Algol type eclipsing binary V477 Cygni (Sp. A3V+F5V, m_v_=8.5, P=2.347days). The binary orbit of the...

An analysis of new spectroscopic and photoelectric UBV observations, satisfactorily covering the whole orbital period of V436 Per, together with existing data allowed us to...

We present the analysis of new BVR light curves for the active star SV Cam. The Roche model with spotted areas on the hotter primary component fits satisfactorily all filter...

We present the results of a systematic search for pulsating components in Algol-type eclipsing binary systems. A total number of 14 eclipsing binaries with A-F spectral type...

New light and radial-velocity curves of V497 Cep, a binary in the open cluster NGC 7160, were obtained and the linear ephemeris of the system was refined to HJD(Min...

The data files includes photometric observations of the eclipsing binary system IU Aurigae. New photometric observations were made on 13 nights at the Ankara University...

Here we present the first Johnson-Cousins VR_C_ light curves of the over-contact binary star GSC 3822-1056. A period study and the light curve solution are also given. An...

We present new accurate CCD uvby light curves for the LMC eclipsing binaries HV 982 and HV 12578, and for the SMC systems HV 1433 and HV 11284 obtained at the Danish 1.5m...

Photometric observations in the R and I bands of the detached M-type double-lined eclipsing binary CU Cnc have been acquired and analysed. The photometric elements obtained from...

The semi-detached eclipsing binary system BP Muscae has been analysed using the Wilson-Devinney program. The physical and orbital parameters have been determined through a...

HD 553 was discovered as an eclipsing binary by Hipparcos. Here, we present the first radial velocity curve for this system. It is found, that HD 553 is a double-lined...

We present photometric observations of the eclipsing binary GR Tau made in 1985, 1993, 1998, 2000 and 2001.

File table1.dat contains the photometric uvby data of the eclipsing binary hypergiant R81 (B2.5 Ia-O) of the Large Magellanic Cloud. The data have been obtained with the Danish...

Spectroscopic orbits of the 12 eclipsing binary systems, TW And, CD And, RS Ari, RU Cnc, TW Cnc, UU Cnc, V788 Cyg, AW Her, MM Her, RV Lib, EW Ori and ZZ UMa are obtained from...

The data file (v899her.dat) includes photometric observations of the eclipsing binary system V899 Herculis. The observations were carried out at the Ankara University...

New BVR light curves and times of minimum light for the short period RS CVn system SV Cam were analysed to derive the physical parameters of the system and the parameters of the...

The present study deals with the problem of the estimation of the orbital and physical parameters for the EB-type eclipsing binary RY Sct, based on the interpretation of new...
