Waiting time distribution of emissions in complex coronal mass ejections

摘要

The waiting time distribution of emissions in Coronal Mass Ejections (CMEs) with several emissions is examined. We define the waiting time as the time interval between the commencement of an emission and the commencement of the next emission considered as parts of a unique CME. The distribution seems to follow a power-law. Two classes of CMEs several emissions are considered: "close" and "separate" depending on angular distance between emissions.
