摘要:

众所周知,日冕物质抛射与相关耀斑之间存在时间关系。加速阶段的持续时间与耀斑上升阶段的持续时间有关。我们研究了与长持续时间耀斑的缓慢上升相(慢LDE)的CME。这些日冕物质抛射的特点是在传播阶段速度很高(v>1000 km/s),而在主加速阶段平均加速度很低。CME被加速直到高度$> 5 R_\odot$,其值高于典型的脉冲CME。与慢激光爆炸有关的日冕物质抛射具有两类日冕物质抛射的特征,即与耀斑有关的日冕物质抛射和与喷发的日冕物质抛射。

英文摘要:

It is well known, that there is temporal relationship between 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 of 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, prolongated, acceleration phase. The CMEs are accelerated until the height $> 5 R_\odot$, 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.
