Hinode has found many and various chromospheric jets (Ca jets). We must verify whether the mechanisms of such jets are all magnetic reconnection (ubiquitous reconnection ?), and investigate the amount of contribution of such jets to the coronal heating process.
Therefore, we will measure the 3D distributions & evolutions of the velocity field (bidirectional flow, reconnection flow, shock wave), temperature, density and magnetic field configuration around various type of jets, by using the HINODE, the 1m solar telescope at Fuxian Solar Obs (FSO) and a spectrograph of the Domeless Solar Telescope (DST) at Hida Obs.
FSO will provide high-spatial resolution imaging data with the H-alphafiltergraph. Hida observatory will provide highly complementary data sets of multi-line spectroscopic observation to Hinode and FSO i.e., DST will take full spectral line profiles of CaII K, H-alpha and CaII 854nm over a FOV of 50"x150" with a time cadence of 10 sec and a moderately high spatial resolution of 1 arcsec or better. |
