Catalogue of the field contact binary stars
Abstract
Abstract. 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 systems the ephemeris for the primary minimum, minimum and maximum visual brightness and equato-rial coordinates are given. If available, photometric elements, (m1 +m2) 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. Key words: contact binaries – photometry – orbital period 1.
