Abstract: Summary We present a new method for the solution of the radiative transfer equation in axial symmetry. The three dimensional problem is reduced to a two dimensional one using a set of independent planes. Our extended short characteristics method is applied to the radiative transfer problem in each of the planes using polar coordinates. The method is able to handle a velocity field, which is accounted for using the Doppler shift between neighboring cells. Our method is suitable for studying the stellar wind with rotation, where the symmetry of the problem is naturally axial. Results of test calculations are shown for the case of a stellar wind of a typical B star.
