Abstract:
To study the flare energetic and energy partition in flare-CME events, we investigate the scaling relationships between several physical parameters during ~40 flare-CME events. We measured the total reconnection fluxes by summing up the photospheric magnetic fluxes swept by spreading flare ribbons. The peak of GOES X-ray radiance is found to be strongly related to the reconnection flux, ribbon distance, and ribbon length. The plasma energetic during each flare is quantified by comparing the 0D EBTEL model with the multi-wavelength observations of the solar corona in EUV and soft X-ray. Based on such measurements, we provide a comprehensive evaluation of various energies in these solar eruptions, including flare radiation, magnetic energy, and CME mechanical energy, and determine the scalings among them.
