Abstract:
An efficient method has been developed for solving the inverse problem of
Doppler-Zeeman mapping of magnetic, chemically peculiar stars. A
regularized iteration method is used to simultaneously solve the integral
equations for the Stokes I, V, Q and U parameters. The validity of
analytical fits to the local profiles of the Stokes parameters is
substantiated. The algorithm had been tested on models and makes it possible
to obtain simultaneously, from the observed Stokes profiles, a map of the
distribution of a chemical element and the parameters of an arbitrarily
shifted magnetic dipole.
