摘要:

我们提出的关联率之间的太阳高能粒子(SEPs)和无线电发射的签名在整个太阳活动周期23的日冕和IP空间。我们选择了与X和M级耀斑从可见的太阳半球的SEP。所有的SEP事件都伴随着日冕物质抛射。在这里,我们专注于SEP事件和动态频谱上的射电II,III和IV型爆发的外观之间的相关性。为此,我们使用了地面站和风/波航天器提供的无线电数据。协会分别介绍了SEP事件伴随活动在东,西太阳半球。我们发现SEP事件与III型爆发的关联率最高,其次是II型和IV型。而对于III型和IV型没有纵向依赖性注意到,这是一个趋势,更高的SEP关联率与II型爆发在东半球。与以前的研究报告的比较进行了简要讨论。

英文摘要:

We present the association rates between solar energetic particles (SEPs) and the radio emission signatures in the corona and IP space during the entire solar cycle 23. We selected SEPs associated with X and M-class flares from the visible solar hemisphere. All SEP events are also accompanied by coronal mass ejections. Here, we focus on the correlation between the SEP events and the appearance of radio type II, III and IV bursts on dynamic spectra. For this we used the available radio data from ground-based stations and the Wind/WAVES spacecraft. The associations are presented separately for SEP events accompanying activity in the eastern and western solar hemisphere. We find the highest association rate of SEP events to be with type III bursts, followed by types II and IV. Whereas for types III and IV no longitudinal dependence is noticed, these is a tendency for a higher SEP-association rate with type II bursts in the eastern hemisphere. A comparison with reports from previous studies is briefly discussed.
