On the properties of contact binary stars [PDF]
, 2004 A catalogue of light curve solutions of contact binary stars has been compiled. It contains the results of 159 light curve solutions. Properties of contact binary stars were studied by using the catalogue data. As it is well known since Lucy's (1968a,b)

AROSATSurvey of Contact Binary Stars [PDF]
, 2006 Contact binary stars are common variable stars which are all believed to emit relatively large fluxes of x-rays. In this work we combine a large new sample of contact binary stars derived from the ROTSE-I telescope with x-ray data from the ROSAT All-Sky ...

Contact Binary Stars as Standard Candles [PDF]
, 1995 The orbital period is a measure of the size of a contact binary star and can be combined with color to predict its luminosity to a fraction of stellar magnitude.

From a Dinuclear System to Close Binary Cosmic Objects
Astronomy, 2023 Applying the ideas from microscopic objects to macroscopic stellar and galactic systems, the evolution of compact di-stars and di-galaxies is studied in the mass asymmetry coordinate. The formation of stable binary systems is analyzed.

Fractal Measures and Nonlinear Dynamics of Overcontact Binaries [PDF]
, 2019 Overcontact binary stars are systems of two stars where the component stars are in contact with each other. This implies that they share a common envelope of gas.
