Abstract

Strong flare events with an extended phase of gamma ray emission from the catalog by Share et al. have been analyzed in order to explain the characteristics of the impulsive and extended phases of such flares and reveal their connection with activity complexes and coronal holes. It is shown that 74% of such events are closely related to activity complexes. It has been qualitatively demonstrated that the particle acceleration processes during the flare development are associated with the changes in the magnetic topology of the flare region and the evolution of the coronal mass ejection. The possible relation of coronal holes to activity complexes and the role of “exchange” reconnection in these processes are discussed.

太阳伽马射线耀斑和活动复合物

摘要

Share等人从目录中收集了扩展的伽马射线发射阶段的强耀斑事件。为了解释这种耀斑的脉冲相和扩展相的特征，并揭示了它们与活动复合物和冠状孔的关系，已经进行了分析。结果表明，此类事件中有74％与活动复合体密切相关。定性地证明了耀斑发展过程中的粒子加速过程与耀斑区域的磁性拓扑结构的变化和日冕物质抛射的发展有关。讨论了冠状孔与活动复合物的可能关系以及“交换”重新连接在这些过程中的作用。
