Sun: Coronal mass ejection (CMEs)

Sažetak
We present a statistical analysis of the relationship between the acceleration of the leading edge of coronal mass ejections (CMEs) and eruptive prominences (EPs). We study the main acceleration phase of 18 CMEs in which kinematics was measured from the pre-eruption stage up to the post-acceleration phase using the data provided by the Extreme Ultraviolet Imaging Telescope, the Mark-IV K-coronameter of the Mauna Loa Solar Observatory, and the Large Angle and Spectrometric Coronagraph. We find a distinct correlation between the duration of the leading edge acceleration phase and prominence acceleration phase. In the majority of events (78%) the acceleration phase of the leading edge is very closely synchronized with the acceleration of the prominence (±20 min). However, in two events acceleration of the leading edge started earlier than the acceleration of the prominence (>50 min), and in two events prominence acceleration started earlier than the acceleration of the leading edge (>40 min).
