cds-question@unistra.frastronomical-modelsstellar-atmosphereseclipsing-binary-starssolar-system-planetsTransiting exoplanets provide unparalleled access to the fundamental parameters of both extrasolar planets and their host stars. We present limb-darkening coefficients (LDCs) for the exoplanet hunting CoRot and Kepler missions. The LDCs are calculated with ATLAS stellar atmospheric model grids and span a wide range of T_eff_, logg, and metallically [M/H]. Both CoRot and Kepler use wide nonstandard photometric filters, and are producing a large inventory of high- quality transiting lightcurves, sensitive to stellar limb darkening. Comparing the stellar model limb darkening to results from the first seven CoRot planets, we find better fits are found when two model intensities at the limb are excluded in the coefficient calculations. This calculation method can help to avoid a major deficiency present at the limbs of the 1D stellar models.2010A&A...510A..21Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/510/A21CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/363/1081 : Non-linear limb-darkening law for LTE models I (Claret 2000)J/A+A/401/657 : Non-linear limb-darkening law for LTE models II (Claret 2003)J/A+AS/114/247 : Limb-darkening coefficients for R I J H K (Claret+ 1995)J/A+A/335/647 : Limb-darkening coefficients for ubvyUBVRIJHK (Claret 1998)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/510/A21https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/510/A21http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/510/A21https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/510/A21https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/510/A21http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/510/A21GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/510/A21/table1Limb-darkening coefficients for CoRoTrecnoRecord number assigned by the VizieR team.
