Scientific paper

An analytical solution of the direct photometric problem for stars with nonhomogeneous temperature spots was developed. Following the suggestion of Mullan (1974, 1984) who has postulated a steady change of temperature as a necessary condition for the origin of spots, the scheme adopted a gradual change of the spot temperature from the center of a spot to its outskirts. The results are intended for the solution of the corresponding inverse problem that will be used to obtain information concerning the mechanisms responsible for the spot origin.
