Abstract

• Finding that the outflow of matter from L$_2$ and resulting angular momentum loss is the principal cause of the long term period decrease.
• Discovery of the systemic velocity changes and finding of the solution for the third body with the orbital period of 398 days, which explains both systemic velocity changes and the variations found in (O--C)$_2$ diagram.
• Transitions from the quiescent to active phase of the contact system can be explained by the tidal forces exerted by the common influence of the third body and fourth body with the orbital period of 16.85 years (found from the light-time effect). This solution is supported by the pronounced variations of the light curve following the periastron passage of the fourth body.

T. Pribulla, J.M. Kreiner, J. Tremko: "Catalogue of the field contact binary stars" (sumbitted to CAOSP)

The catalogue of 361 galactic contact binaries is presented. Enlisted contact binaries are divided into five groups according to the type and quality of the available observations and parameters. For all systems the ephemeris for the primary minimum, minimum and maximum visual brightness and equatorial coordinates are given. If available, photometric elements, $(m_1 + m_2) \sin^3 i$, spectral type, parallax and magnitude of the O'Connell effect are also given. Photometric data for several systems are augmented by new observations. The quality of the available data is assessed and systems requiring modern light-curve solutions are selected. Selected statistical properties of the collected data are discussed.
