cds-question@unistra.frmultiple-starsorbitsstellar-massesBased on positional observations and measurements of radial velocities, the orbits of 850 wide visual double stars have been determined. The parameters of the log-normal distributions for the histograms of orbital periods, stellar masses, and semi-major axes in astronomical units have been obtained. The eccentricity histogram for binary stars with orbital periods less than 400 years follows a normal distribution centered at e=0.545+/-0.029. For stars with longer periods, this distribution obeys the law f=2e, with accuracy to errors. The mass-to-luminosity relation for stars with well-determined masses is given by: logL_{sun}_=4.33logM_{sun}_-0.11, where L_{sun}_ and M_{sun}_ are the luminosity and mass of the star in units of the solar luminosity and mass, respectively.2025RAA....25a5016Ihttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/RAA/25.A5016CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/wds : The Washington Visual Double Star Catalog (Mason+ 2001-2020)I/355 : Gaia DR3 Part 1.
