Analytical Limb-darkening Elliptical or Spherical – ALDES
Description
ALDES provides intensity maps (images) or 1d intensity profiles for spherical or elliptical stars showing the limb darkening (LD) effect. Different LD laws are offered: uniform disk, linear, power law, quadratic, square root, logarithmic and four-parameter. The coefficients for each LD law should be provided by the user. If necessary, in the "Documentation and acknowledgments" there are some useful references providing several values of LD coefficients for different LD laws, stellar types, and spectral domains. The analytical forms of the LD laws are also given. The specific intensity maps are normalized such that the center of the image is equal to 1.
The ALDES model was created by A. Domiciano de Souza and N. Bruot.
Limb darkening (LD) coefficients for different LD laws, stellar types, and spectral domains can be found for example in the following papers and catalogues:
