Abstract:
Suites of instruments aboard the Solar Dynamics Observatory (SDO) and the Solar-Terrestrial Relations Observatory (STEREO) spacecraft offer a set of new observations from multiple viewpoints that can be combined with theory and numerical modeling to provide a better understanding of CME initiation and energy release in eruptive flares. In situ observations of heavy ion charge state composition are a direct measure of the plasma properties in the CME source region in the corona. The ionic charge state composition of ejecta material is determined by the temperature and density evolution of plasma during eruptive flares. We will investigate the flare contribution to CME heating by examining the relationship between observed profiles of flare emission and the corresponding in situ ionic charge state observations. We will demonstrate the feasibility of using multi-wavelength EUV observations of the eruptive flare as constraints in the modeling of CME plasma evolution and its ionic charge state composition.
