cds-question@unistra.freclipsing-binary-starsastronomical-modelsstellar-atmospheresWe present monochromatic, passband-specific, and bolometric limb-darkening coefficients for a linear as well as nonlinear logarithmic and square root limb-darkening laws. These coefficients, including the bolometric ones, are needed when modeling binary star light curves with the latest version of the Wilson-Devinney light curve program. We base our calculations on the most recent ATLAS stellar atmosphere models for solar chemical composition stars with a wide range of effective temperatures and surface gravities. We examine how well various limb-darkening approximations represent the variation of the emerging specific intensity across a stellar surface as computed according to the model. For binary star light curve modeling purposes, we propose the use of a logarithmic or a square root law. We design our tables in such a manner that the relative quality of either law with respect to another can be easily compared. Since the computation of bolometric limb-darkening coefficients first requires monochromatic coefficients, we also offer tables of these coefficients (at 1221 wavelength values between 0.09 nm and 160 {mu}m) and tables of passband-specific coefficients for commonly used photometric filters.1993AJ....106.2096Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/106/2096CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/106/2096https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/106/2096http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/106/2096https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/106/2096https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/106/2096http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/106/2096GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/AJ/106/2096/table1Bolometric limb-darkening coefficientsrecnoRecord number assigned by the VizieR team.
