We present the results of a statistical study of the magnetic structure of upper main sequence chemically peculiar stars. We have modelled a sample of 34 stars, assuming that the magnetic morphology is described by the superposition of a dipole and a

We present a generalized frequency redistribution function for the polarized two-term atom in an arbitrary magnetic field. This result is derived within a new formulation of the quantum problem of coherent scattering of polarized radiation by atoms i

A system of four differential equations for the radiative transfer of polarized light is derived by a density matrix technique. Calculations regarding radiation are completely developed while no assumptions are made about the material system interact

The general properties of the transfer equations for polarized radiation are discussed in detail and some relevant symmetries about the absorption matrix and the emission vector are deduced. A geometrical picture of the process of radiative transfer

The interaction between a material system and an arbitrarily polarized radiation field is investigated by a density matrix technique, to obtain the radiative rates for the statistical equilibrium equations. No assumptions are made about the nature of

A general formalism is presented to obtain an analytical solution of the radiative transfer equations for polarized radiation when the absorption Mueller matrix for the Stokes parameters is constant along the ray-path. The formalism is then applied t

Magnetic intensification is proposed as a mechanism to explain the general features of the variable broad-band linear polarization emerging from rotating magnetic stars. This mechanism is studied in detail, and some efforts are made to investigate th
