The Hanle Effect in the Ly? Lines of H I and He II for Measuring the Magnetic Fields of the Solar Transition Region
Original language description
Here we present some theoretical predictions concerning the amplitudes and magnetic sensitivities of the linear polarization signals produced by scattering processes in these strong emission lines of the solar transition region, taking into account radiative transfer and the Hanle effect caused by the presence of organized and random magnetic fields. We find that the line-center amplitudes of the fractional polarization signals vary typically between a fraction of a percent and similar to 1%, dependingon the Ly alpha line under consideration, the scattering geometry and the strength and orientation of the magnetic field.
