Coronal mass ejections associated with LDE flares displaying a slow rise phase
Abstract
It is well known, that there is a temporal relationship between coronal mass ejections (CMEs) and associated flares. The duration of the acceleration phase is related to the duration of the rise phase of a flare. We investigated CMEs associated with long duration flares displaying a slow rise phase (slow LDE). These CMEs are characterized by high velocity (v>1000 km/s) during the propagation phase and low average acceleration during the main, prolonged, acceleration phase. The CMEs are accelerated until the height > 5 R_⊙, which is higher value than in typical impulsive CMEs. CMEs associated with slow LDEs have characteristics of both classes of CMEs, i.e. CMEs associated with flares and CMEs associated with eruptive prominences.
