cds-question@unistra.frastronomical-modelsstellar-atmosphereslate-type-starsWe compute the emergent stellar spectra from the UV to far infrared for different viewing angles using realistic 3D model atmospheres for a large range in stellar parameters to predict the stellar limb darkening. We have computed full 3D LTE synthetic spectra based on 3D radiative hydrodynamic atmosphere models from the Stagger-grid in the ranges: Teff from 4000 to 7000K, logg from 1.5 to 5.0, and [Fe/H], from -4.0 to +0.5. From the resulting intensities at different wavelength, we derived coefficients for the standard limb darkening laws considering a number of often-used photometric filters. Furthermore, we calculated theoretical transit light curves, in order to quantify the differences between predictions by the widely used 1D model atmosphere and our 3D models.2015A&A...573A..90Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/573/A90CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/557/A26 : STAGGER-grid of 3D stellar models.
