VizieR Online Data Catalog: Center-to-limb polarization of FGK stars (Kostogryz+, 2016)
Abstract
Calculated center-to-limb variations of intensity (limb darkening) for different stellar parameters with spherical atmosphere model approximation. All intensities are normalized to the intensity in the center of stellar disks, therefore, in the centre of the disks (mu=1.0), I(mu)/I(1.0)=1.0. The parameters of spherical Phoenix stellar model atmospheres we considered here are the following: effective temperature is in the range of 4000K-7000K with the step of 100K and for logg=1.0-5.5 with the step of 0.5. All calculations are made for such wavelengths: 4000Å, 4500Å, 5000Å, 6000Å, 7000Å. We also present the position of the stellar limb and calculated stellar radius.
