The Scattering Polarization of the Ly? Lines of H I and He II Taking into Account Partial Frequency Redistribution and J-state Interference Effects
Original language description
We relax both approximations and show that the joint action of partial frequency redistribution and J-state interference produces much more complex fractional linear polarization (Q/I) profiles, with large amplitudes in their wings. Such wing polarization signals turn out to be very sensitive to the temperature structure of the atmospheric model, so that they can be exploited for constraining the thermal properties of the solar chromosphere. Finally, we show that the approximation of CRD without J-stateinterference is however suitable for estimating the amplitude of the linear polarization signals in the core of the lines, where the Hanle effect operates.
