cds-question@unistra.frastronomical-modelsstellar-atmospheresphotometryOne of the biggest problems we can encounter while dealing with the limb-darkening coefficients for stellar atmospheric models with spherical symmetry is the difficulty of adjusting both the limb and the central parts simultaneously. In particular, the regions near the drop-offs are not well reproduced for most models, depending on Teff, log g, or wavelength. Even if the law with four terms is used, these disagreements still persist. Here we introduce a new method that considerably improves the description of both the limb and the central parts and that will allow users to test models of stellar atmospheres with spherical symmetry more accurately in environments such as exoplanetary transits, eclipsing binaries, etc.2018A&A...618A..20Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/618/A20CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/363/1081 : Non-linear limb-darkening law for LTE models (Claret, 2000)J/A+A/529/A75 : Limb-darkening coefficients (Claret+, 2011)J/A+A/546/A14 : Limb-darkening for CoRoT, Kepler, Spitzer (Claret+, 2012)J/A+A/600/A30 : Limb-darkening for TESS satellite (Claret, 2017)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/618/A20https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/618/A20http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/618/A20https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/618/A20https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/618/A20http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/618/A20GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/618/A20/TESSqa,b quadratic LDCs, PHOENIX models for TESSrecnoRecord number assigned by the VizieR team.
