Scientific paper

The main acceleration phase of coronal mass ejections (CMEs) is the direct manifestation of the dominant magnetic driving forces. Thus, quantifying CME kinematics is fundamental for understanding the driving mechanisms of CMEs and for testing theoretical models of CME initiation, eruption, and propagation. We investigate the main acceleration phase of CMEs using information theoretic model selection to estimate the velocity and acceleration of complex trajectories. This approach permits the objective characterization and classification of CME dynamics. The entire catalog of CMEs observed by Large Angle Spectrometric Coronagraph (~12,000 events) has been examined, augmented with observations of eruptive prominences observed by the Extreme Ultraviolet Imaging telescope, Nobeyama Radioheliograph, Big Bear Solar Observatory, and Kanzelhöehe Solar Observatory. A subset of the CMEs that exhibit clear well-resolved main phase acceleration are analyzed in detail. The statistics of the magitude and time-scale of the main phase acceleration are discussed as well as the relative timing of the acceleration with respect to the GOES X-ray flux.
