论文摘要
我们已经统计分析了II型和III型的115个低频（十分升高的波长范围）和与主要太阳能粒子（SEP：EP> 10 MEV）事件相关的II型和III型爆发，及其太阳能原因，例如太阳能和冠状量和冠状质量弹出（CMES）（CMES），从1997年到2014年。冲动的耀斑（持续时间<60分钟）和40个逐渐耀斑（持续时间> 60分钟）。与冲动耀斑相关的SEP事件（RT = 989.23 min：2.86天）短暂寿命，并且与渐进的相关事件相比，它们很快达到了峰值强度（较短的上升时间）（RT = 1275.45 min：3.34天：3.34：3.34天）。我们发现所有SEP的对数峰强度与CME的性能之间存在良好的相关性（空间速度：CC = 0.52，SECC = 0.083）和太阳耀斑（log Integated Flux：cc = 0.44，secc = 0.083）。对于这组主要的SEP事件，该特定结果没有在耀斑相关和与CME相关的SEP事件之间进行明确的区别。我们从风/波观察到的无线电动力光谱中得出了这些爆发的峰强度，积分强度，持续时间和斜率。 DH II型爆发的大多数特性（峰强度，集成强度和起始频率）与冲动性和渐进式耀斑事件相关的II型爆发都相似。此外，我们还发现SEP的性质与DH III型爆发的关键参数之间存在显着相关性。该结果表明，与DH III型无线电爆发的特性相比，与DH II型无线电爆发相比，SEP的峰强度与DH型无线电爆发的性质更紧密，至少对于这组115个重大的SEP事件。
We have statistically analyzed a set of 115 low frequency (Deca- Hectometer wavelengths range) type II and type III bursts associated with major Solar Energetic Particle (SEP: Ep > 10 MeV) events and their solar causes such as solar flares and coronal mass ejections (CMEs) observed from 1997 to 2014. We classified them into two sets of events based on the duration of the associated solar flares:75 impulsive flares (duration < 60 min) and 40 gradual flares (duration > 60 min).The impulsive flare-associated SEP events (Rt = 989.23 min: 2.86 days) are short lived and they quickly reach their peak intensity (shorter rise time) when compared with gradual flares associated events (Rt =1275.45 min: 3.34 days). We found a good correlation between the logarithmic peak intensity of all SEPs and properties of CMEs (space speed: cc = 0.52, SEcc = 0.083), and solar flares (log integrated flux: cc = 0.44, SEcc = 0.083). This particular result gives no clear cut distinction between flare-related and CME-related SEP events for this set of major SEP events. We derived the peak intensity, integrated intensity, duration and slope of these bursts from the radio dynamic spectra observed by Wind/WAVES. Most of the properties (peak intensity, integrated intensity and starting frequency) of DH type II bursts associated with impulsive and gradual flare events are found to be similar in magnitudes. In addition, we also found a significant correlation between the properties of SEPs and key parameters of DH type III bursts. This result shows a closer association of peak intensity of the SEPs with the properties of DH type III radio bursts than with the properties DH type II radio bursts, at least for this set of 115 major SEP events.
