摘要:

本文分析了SBRS在第24周上升相两年多时间里观测到的具有精细结构的放射性尘埃。在斑马结构的五个事件中,观察到各种纤维爆发和快速脉动。2011年2月15日和24日的事件最令人感兴趣。这三种情况下的射电辐射偏振都与射电辐射的常波模式有关,微波范围内的事件几乎都含有超精细结构。可能每种精细结构都是由相同的机制激发的,并且各种各样的事件与耀斑过程的动力学有关。

英文摘要:

Radiobursts exibiting fine structure observed over two years during the rising phase of Cycle 24 by the SBRS are analyzed. In five events zebra structure, various fiber bursts and fast pulsations were observed. Events on 15 and 24 February 2011 are of the greatest interest. The polarization of radio emission in all three cases is related to the ordinary wave mode of radio emission.Almost all events in the microwave range contain superfine structure. It is possible that each type of fine structure is excited by the same mechanism, and the broad variety of events is related to the dynamics of flare processes.
