THE ASSOCIATIVE PROCESSES OF SOLAR MICROWAVE BURSTS WITH ENERGETIC PROTONS
-
摘要: 本文根据近年来对太阳射电爆发与高能质子/γ射线谱线辐射等观测资料的统计分析,得出不同型别的太阳射电爆发中以微波爆发与γ射线辐射/质子事件发生过程中的高能质子共生率最高,趋近100%,这一结果,否定了以前认为米波Ⅱ型或米波Ⅳ型爆发拥有产生高能质子必要条件的看法;指出:上述微波爆发可以细分为脉冲型和微波Ⅳ型(Ⅳμ型),它们的物理条件不同,共生关系的表现特征也不尽相同;并且对上述共生现象的物理过程作了初步的解释和探讨.Abstract: In the paper,it is shown that neither type Ⅱ nor meter-wave type Ⅳ but intense microwave bursts are nearly always associated with energetic protons by data analysis of recent observations of solar radio bursts and associated γ-ray emissions/proton events.The result is contrary to the previous long-held views.The microwave bursts associated with energetic protons can be divided into two classes:impulsive and type Ⅳμ bursts.The former is associated with much more happed or interacting protons than the escaping ones,but the latter often associated with more escaping protons. Furthermore,the efficient acceleration processes for the different cases in solar microwave bursts and the reasons why the intense microwave bursts are nearly always associated with energetic protons are also discussed.
