J/A+A/437/375   Approximate elements of eclipsing binaries    (Dryomova+, 2005)

Catalog of orbital elements, masses and luminosities of short-periodic RS CVn-type eclipsing systems. Dryomova G.N., Perevozkina E.L., Svechnikov M.A. <Astron. Astrophys. 437, 375 (2005)> =2005A&A...437..375D
ADC_Keywords: Binaries, eclipsing ; Combined data Keywords: binaries: eclipsing - catalogs - stars: fundamental parameters Abstract: The new data on the orbital elements, masses and luminosities have been collected for 31 pre-contact binary systems of short-periodic RS CVn type. The results of statistical treatment of the catalogue data pursue the goal of an accurate definition of the properties and evolutionary status of the given class systems. The ages of pre-contact systems have been estimated by isochrone method. Numerous comments and bibliographic references to the catalogue are accessible. File Summary:

Note (1): In the square brackets SP2 computed from the known spectrum SP1 and the ratio J1/J2. Note (2): Note on mass ratio of components is numbered as follows: 0 = if q is found from double-lined spectra; 1 = if q is found from photometrical light-curve; 2 = if q is found by the relation (M-L) with the using mass function from single-lined spectrum. Note (3): Absolute bolometric magnitudes are calculated by their geometrical parameters, spectral and luminosity classes. We used effective temperature scale of Popper, 1980ARA&A..18..115. Note (4): Weight characterizes the reliability of evaluation of photometric and absolute elements in 10-ball scale (highly unreliable elements have weight 0; elements, evaluated with reliability, approaching to reliability of the evaluation of elements by exact methods over their light curves and radial velocity curves have W=9. For systems with certain meaning of SP1 the elements are defined more certainly and they have weight essentially larger than systems with uncertain component spectrum. Note (5): We used evolution models of Maeder & Meynet, 1988A&AS...76..411M.
