The relation between explosive events and photospheric magnetic fields
Abstract
The relationship between explosive events and photospheric magnetic fields in a quiet region is studied by high resolution data obtained with EIS and SOT on board Hinode. Data from quiet regions near the disk center were selected and reduced in this paper. He II λ 256.32 (log Te = 4.7) and other emission lines from the transition region were analyzed to find a signature of explosive events. Many line-broadening features are found in the transition region, while they are not found in the coronal emission lines such as Fe XII λ 195.12. Spectropolarimeter (SP) allowed us to study photospheric magnetic fields with unprecedentedly high resolution. In addition, the evolution of magnetic fields was captured by Narrowband filter imager (NFI). The result indicates that explosive events occurred around magnetic field patches in the network.
