Abstract

A precise analytic expression is obtained for calculation of the spotted stars light variations in the case of arbitrary radius of the spot and arbitrary inclination of the rotation axis of the star with reference to the line of sight by adopting a linear law for limb darkening of both the star and the spot but with different coefficients of darkening. The results obtained can be used for the calculation of the light curves of the spotted stars with an arbitrary number of spots on the surface of the star.
