Investigation of Limb darkening for short period AB Andromeda eclipsing binary star

Abstract

This work deal with characterizing the limb darkening coefficients for the
short period binary stars AB Andromeda to determine the size,
luminosities and masses of the Individual stars as well as orbital size and
orientation of the binary system. Calculating limb darkening for
monochromatic pass bounds, the visual rang i.e. intermediate (uvby)
have been calculated and broad bands to the near infrared. Also
bolometric limb darkening coefficients for a linear as well as nonlinear
logarithmic and square root limb darkening law as function of surface
effective temperatures covering a wide range and surface have been
computed. The calculations and computing have been carried out by using
the interpolation program of Van Hamme.
