Research Abstract

We developed a two-dimensional spectro-polarimetoric observation method to detect unsolved chromospheric jets and heating phenomena effectively and to derive their physical parameters, particularly the magnetic and velocity fields, as accurately as possible. Using observational data coordinated with other ground-based instruments and the solar observing satellite Hinode, we newly revealed that the jets have a large line-of-sight velocity and often twin structure and uni-polar magnetic elements at their feet show vortex and encountering motion. Our results suggest a new type of magnetic reconnection mechanism in the chromospheres and its contribution to the chromospheric heating.
