爆发日珥与日冕物质抛射的观测研究

TWO ERUPTIVE PROMINENCES AND A CME ON FEBRUARY 9, 1982

本文比较了1982年2月9日同时观测到的两个爆发日珥及一次白光日冕物质抛射事件。比较表明,在研究日冕物质抛射事件与爆发日珥的关系时,爆发日珥的形状可能是一个重要的因素,它体现了局部区域磁场结构的变化。作者提出了一种可能的磁场结构模型,对观测结果给以解释。

Two Ha eruptive prominences located at N10W90 and S14W90, respectively, were observed simultaneously on February 9, 1982. A CME corresponding to the northern one was observed by the satellite p78-1. No CME was found for the much larger southern prominence which was associated with an intense radio burst. A comparison of the two eruptive prominences shows that the shape of an eruptive prominence and its change with time could be an important factor in its association with a CME. A qualitative model of magnetic configuration which gives a possible explanation of the observed results is proposed.
