cds-question@unistra.frg-starssolar-system-planetsspectroscopyWe compare limb darkening laws derived from 3D hydrodynamical model atmospheres and 1D hydrostatic MARCS models for the host stars of two well-studied transiting exoplanet systems, the late-type dwarfs HD 209458 and HD 189733. The surface brightness distribution of the stellar disks is calculated for a wide spectral range using 3D LTE spectrum formation and opacity sampling. We test our theoretical predictions using least-squares fits of model light curves to wavelength-integrated primary eclipses that were observed with the Hubble Space Telescope (HST).2012A&A...539A.102Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/539/A102CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/510/A21 : Stellar Limb-Darkening Coefficients (Sing, 2010)J/A+A/526/A71 : C abundances in G and K nearby stars (Da Silva+, 2011)J/A+A/529/A75 : Limb-darkening coefficients (Claret+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/539/A102https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/539/A102http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/539/A102https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/539/A102https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/539/A102http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/539/A102GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/539/A102/hd189733HD 189733 intensitiesrecnoRecord number assigned by the VizieR team.
