Understanding Solar Energetic Events Using the Next Generation Coronagraph: High-resolution Imaging with Diagnostic Capability
Abstract
What is the mechanism for CME initiation? Soon for the first time coronagraphs will image and resolve
the magnetic field structural changes in the Corona that lead to the onset of Coronal Mass Ejections (CMEs). The data provided by these instruments will for the first time provide a time sequence of high-resolution images showing the looptop regions where reconnection leading to flares and the acceleration of energetic particles takes place. These data will enable the determination of the CME initiation mechanism, without which it is impossible to understand the physics of the triggering of energetic events on the Sun. The determination of the cause of flare onset would be major step toward advance forecasting of CME’s that drive the radiation environment in near Earth space, and the solar system in general. These data will also show the magnetic connectivity of the low corona out to the orbit of Solar Probe Plus and Solar Orbiter.- Publication:
