EFFECT OF THE CORONAL MAGNETIC FIELD AND THE SOLAR WIND VELOCITY FIELD VECTORS ON THE POLARIZATION OF THE O Ⅵ λ1032 LINE

摘要

Numerical computation results of the combination of the Hanle effect (due to the coronal magnetic field) and to the Doppler redistribution effect (due to the solar wind velocity field) on the linear polarization parameters of the O Ⅵ λ1032 coronal line (hereafter D_2 line) are presented. Constraints on the magnetic field and the solar wind velocity field vectors are obtained by comparing the present results and the measurements of the polarization parameters of the O Ⅵ D_2 coronal line by using SUMER/SoHO polari-metric observations done in the south coronal polar hole during the minimum of the solar activity cycle.
