We have compiled a catalogue of light curve solutions of contact binary stars. It contains the results of 159 light curve solutions. The properties of contact binary stars were studied using the catalogue data. 
As is well known since Lucy's ([CITE],b) and Mochnacki's ([CITE]) studies, primary components transfer their own energy to the secondary star via the common envelope around the two stars. This transfer was parameterized by a transfer parameter (ratio of the observed and intrinsic…

Statistics of 700 Individually Studied W UMa Stars

We present a statistical study of the largest bibliographic compilation of stellar and orbital parameters of W UMa stars derived by light-curve synthesis with Roche models. The compilation includes

Analysis of dual band and survey photometry of two low mass ratio contact binary systems

. The study presents photometric analysis of the completely eclipsing contact binary systems TYC 8351-1081-1 and ASAS J210406-0522.3. TYC 8351-1081-1 is an extremely low mass ratio (q = 0.086) system

Physical parameters of 62 eclipsing binary stars using the ASAS-3 data$-$I

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 project between

Modelling of W UMa-type variable stars

Most of the stars in the sky are binary or multiple star systems. In only a small percentage of binary systems are the two stars far enough apart to be able to resolve the individual stars. The

Distribution of physical parameters for 380 contact binaries in the Kepler field

We present the physical parameters (p, T, q, i, f) of 380 Kepler contact binary systems (hereafter called CBs). A statistical study on the CBs is carried out based on a Kepler photometric database.

The First Photometric Investigation of the Neglected Contact Binary LP Comae

In this paper, we present the first complete photometric light curves in the B, V, and R passbands of the neglected contact binary LP Com. Based on the Wilson–Devinney code, it has been found that

Chromospheric activity in bright contact binary stars

Context. Studying chromospheric activity of contact binaries is an effective way of revealing the magnetic activity processes of these systems. One efficient but somewhat neglected method for this

The First Photometric Study of the Short-period Shallow Contact System LO Comae

In this paper, the first complete photometric light curves in the B, V, and R passbands for an eclipsing binary LO Com are presented, and the photometric solution for the LO Com is derived by

Catalogue of the field contact binary stars

A catalogue of 361 galactic contact binaries is presented. Listed contact binaries are divided into five groups according to the type and quality of the available observations and parameters. For all

Observed Properties of Contact Binary Systems

A group of close eclipsing systems, which continues to pose a challenge in many subjects of modern astrophysics, is that of contact binaries. In this study, using the most recent observational data

The structure of contact binaries

In a preceding paper a simple model for contact binaries has been proposed, based on the usual assumption that the energy sources/sinks caused by the interaction of the components occur only in the

ABSOLUTE MAGNITUDE CALIBRATION FOR THE W UMA-TYPE SYSTEMS BASED ON HIPPARCOS DATA

Hipparcos parallax data for 40 contact binary stars of the W UMa-type (with epsilon MV < 0.5) are used to derive a new, (B-V)-based absolute-magnitude calibration of the form MV = MV(log P,B-V). The

Observational tests of theories of contact binaries

Two recent theories of the structure of contact binaries are subjected to a wide variety of observational tests. One theory, according to which a W UMa system at or near zero-age cannot achieve

Contact binary stars

Data on 37 W Ursae Majoris systems have been collected. Densities, corrected primary colors, minimum periods, inferred masses, luminosities, and specific angular momenta are computed. The A-type

Abstract The GCVS (General Catalogue of Variable Stars) project, initiated, on behalf of the IAU, by P. P. Parenago and B. V. Kukarkin in the fourties, is now facing the necessity of serious changes

The structure equations of contact binaries

The structure equations of contact binaries are discussed. An equation for the transfer of mass between the com- ponents is derived. Serious uncertainties concern only the transfer of energy. They
