Chromospheric diagnosis with forward scattering polarization

摘要

Is it physically feasible to perform chromospheric diagnosis using spatialmaps of scattering polarization at the solar disk center? To investigate it wesynthesized polarization maps (in 8542 Angstroms) resulting from MHD solarmodels and NLTE radiative transfer calculations that consider Hanle effect andvertical macroscopic motions. After explaining the physical con- text offorward scattering and presenting our results, we arrive at the definition ofHanle polarity inversion lines. We show how such features can give support fora clearer chromospheric diagnosis in which the magnetic and dynamic effects inthe scattering polarization could be disentangled.
