H-alpha Polarimetry and Magnetic Field Structure in the Chromosphere

Y. Hanaoka

We have developed a high-precision polarimeter with ferroelectric liquid crystals, and it enables us to get full-Stokes polarization data of the chromosphere in the H-alpha line with the precision of the order of 10^-4. It revealed that polarization data taken at different wavelengths in the H-alpha wing show the magnetic field information at different height in the chromosphere. This means that three dimensional magnetic field structure in the chromosphere can be inferred from the H-alpha polarimetry data.
