Vilnius Photometry of HD211853
New photometric observations of the Wolf-Rayet binary HD 211853 are presented. They were obtained with the 1-m reflector of the Institute of Theretical Physics and Astrophysics... -

Transits observed in OGLE 2001-2003
We present results of an extensive photometric search for planetary and low-luminosity object transits in the Galactic disk stars commencing the third phase of the Optical... -
Parameters of eclipsing binaries
An iterative method has been used to compute the geometric and physical parameters of 1048 eclipsing binary stars. -
UNSW catalog of Variable Stars
We present a new catalogue of variable stars compiled from the data taken for the University of New South Wales Extrasolar Planet Search. From 2004 October to 2007 May, 25... -
M/L relation of intermediate-mass stars
The mass-luminosity relation (MLR) for intermediate-mass stars is based on data on detached main-sequence double-lined eclipsing binaries (DM-DLEB). However, there is a notable... -
BV differential light curves of EQ Tau
We present two new sets of complete light curves of EQ Tauri (EQ Tau) observed in 2000 October and 2004 December. These were analysed, together with the light curves obtained by... -
Ephemeris of V382 Cyg and TU Mus
Up to now, V382 Cyg and TU Mus are the only two discovered O-type overcontact binary stars with periods less than two days (P=1.8855 and 1.3873d). Both systems contain a visual... -
XX Cep BVRI light curves
We obtained CCD photometric observations of the Algol-type semidetached binary XX Cephei (XX Cep) during 15 nights from 2002 September 17 to 2003 February 2, and also on 2005... -
Eclipsing Binary with Eccentric Orbits Catalog
A new catalog of eclipsing binary stars with eccentric orbits is presented. The catalog lists the physical parameters (including apsidal motion parameters) of 124 eclipsing... -
New times of minima of VZ CVn
We present new photometric two-colour observations of the double-lined close binary star VZ CVn. Combining two data sets obtained in 1971-72 and in 2006, the physical parameters... -
Spectra of 5 faint cataclysmic variables
We present medium-resolution VLT/FORS2 spectroscopy of six cataclysmic variables (CVs) discovered by the Sloan Digital Sky Survey (SDSS). We determine orbital periods for SDSS... -
Angular momentum evolution of Algol binaries
We have compiled the well-determined absolute parameters of Algol-type binaries. The lists contain the parameters of 74 detached and 61 semi-detached close binaries. The... -
Catalogue of close binaries
A catalogue of close eclipsing binary systems (detached and semidetached) with at least one of the components located in the delta Scuti region of the Cepheid instability strip... -
Eclipsing binaries in eastern spiral arm of M31
The results of an archival survey are presented using B, V-band imaging of the eastern spiral arm of M31. Focusing on the eclipsing binary star population, a matched-filter... -
U Gem spectroscopy
We present a phase-resolved spectroscopic study of the secondary star in the cataclysmic variable (CV) U Gem. We use our data to measure the radial velocity semi-amplitude,... -
Kinematics of W UMa-type binaries
The kinematics of 129 W Ursae Majoris type binaries (W UMas) were studied. The sample is heterogeneous with different orbits and physically different components from F to K... -
uvby photometry of AB Cas
Table 1 contents 1313 simultaneous measurements collected in each of the four uvby colours of the Stromgren photometric system for the semi-detached Algol-type eclipsing binary...
