| 摘 要： | 本文对盔状冕流底部磁通量喷发的大气响应进行数值模拟。数值结果表明:在喷发磁场的作用下,原冕流中的物质将受到压缩并向上运动,形成高密度亮环结构,同时在环的前方出现快磁声波,在环的下方出现低密度暗区。据此我们认为,磁通量喷发可能是触发环形日冕物质喷射的一种重要机制。

| Abstract: | This paper presents a numerical simulation of the solar atmosheric response to a magnetic flux eruption from the base of a helmet streamer. The numerical results show that the material contained originally in the streamer is compressed and lifted upward by the erupting magnetic field, forming a high density bright loop. At the same time, fast magnetosonic waves occur in front of the loop, and a dark region with low density comes out below it. Based on these, we believe that the magnetic fltx eruption is probably an important mechanism in triggering loop-like coronal mass ejections. |
