BSN. II. The First Light Curve Study of Eight Total Eclipsing Contact Binary Stars with Shallow Fillout Factors [PDF]
Astronomical JournalThis study provides the first comprehensive analysis of eight total-eclipse W Ursae Majoris-type contact binary systems. Ground-based photometric multiband observations were conducted at a Mexican observatory, and new times of minima were extracted.

The Astrophysical Journal, 1981 Densities, corrected primary colors, minimum periods, inferred masses, luminosities, and specific angular momenta are computed from data on 37 W Ursae Majoris systems. A-type systems, having lower densities and angular momenta than the W-type systems, are shown to be evolved, and a new class of contact binary is identified, the OO Aquilae systems ...

The evolution of binary stars into contact states [PDF]
Space Science Reviews, 1989 AbstractGood-quality empirical results on 62 short-period binary stars recently summarised by Hilditch & Bell (1987) and Hilditch, King & McFarlane (1988) are discussed in terms of evolutionary paths from detached to semi-detached and contact states.

Contact binary stars. I - an X-ray survey
The Astrophysical Journal, 1984 X-ray emission from a contact binary star was first detected by the HEAO 1 satellite in 1977. Spectroscopic observations of 44i Boo and VW Cep by IUE established the presence of high-temperature chromospheric and transition region emission lines in the spectra of these stars.

The uniqueness of determination of the photometric mass ratio of contact binary stars with applications to selected binaries [PDF]
Contributions of the Astronomical Observatory Skalnaté Pleso. We have used a Roche-geometry code to pre-generate light curves of contact binary stars using only mass ratio q , fill out f of the Roche lobes, and the inclination i of the orbital plane.

A Method of Measuring Gamma-Velocities of Contact Binary Stars [PDF]
International Astronomical Union Colloquium, 1999 AbstractGamma-velocities of bright contact binary stars (VW Cep, SW Lac, AB And, OO Aql) have been computed using cross-correlation. The template spectra were synthesized with a newly developed computer code WGMODEL.
