| Outline of Final Research Achievements |
Magnetohydrodynamic waves in the solar chromosphere transfer magnetic energy stored in the solar photosphere and the convection zone to the upper atmosphere, i.e., the chromosphere and the corona. Therefore, it is important to study the waves to solve the acceleration of the solar wind, or heating in the solar chromosphere and the corona. However, it is yet unclear how much energy is transferred by the waves. Magnetic structures extending from the photosphere into the chromosphere determines the amount of the transferred energy, because reflections, refractions, interferences, and growths to the shock of the waves depends on it. In this study, we developed a spectropolarimeter on the Domeless Solar Telescope at Hida Observatory, which enable us to measure multi wavelength ranges simultaneously, in order to measure the magnetic structures.
