THE QUASI-PERIODIC OSCILLATION OF SQLAR RADIO BURST OBSERVED ON DIFFERENT FREQUENCIES
-
摘要: 本文对1989年4月9日与4B级大耀斑伴生的两个波段(3750 MHz,2840 MHz)的射电大爆发进行了简单的初步分析。结果表明:这两个波段的爆发不仅各自具有繁多的周期,而且都存在30+3s的准周期振荡。这种现象可能与磁环的准周期振荡有关,或与粒子流有关。Abstract: In this paper,the quasi-periodic oscillations of solar radio burst observed on different frequencies are discussed.The period of the oscillation is about 30 seconds.Such an oscillation might be associated with Alfven waves that traverse the magnetic loop of the lower corona.
