Research of solar active phenomena by mean of a new plasma diagnosis with spectro-polarimetory

京都大学希达天文台的无圆顶太阳望远镜上研制了一种新的分光偏振计，旨在实现对动态太阳等离子体磁场和电场等物理量的新诊断。在中性氢帕邢系列谱线上观测到了日边色球物质喷射现象（喷流），首次证明了磁场与喷流成一直线，中性氢被磁场高度冻结。

A new spectro-polarimeter was developed on the Domeless Solar Telescope at Hida observatory of Kyoto University aiming for realise new diagnosis of physical quantities such as magnetic field and electric fields of dynamic solar plasma. Chromospheric mass ejection phenomena (jets) occured on the solar limb were observed in spectral lines of Paschen series of neutral hydrogen and it was demonstrated that the magnetic field is aligned with the jets and neutral hydrogen is highly frozen to the magnetic field for the first time.
