日冕物质抛射及其驱动激波的多波段和多视角研究

Multi-wavelength and Multi-perspective Studies of Coronal Mass Ejections and Their Driven Shocks

日冕物质抛射(Coronal Mass Ejection,CME)是太阳大气中剧烈的爆发现象之一.其爆发通常能释放大量的能量并抛射大量磁化等离子体.CME所驱动的激波能进一步导致太阳高能粒子事件(Solar Energetic Particle,SEP)的发生,并可能影响航天器和宇航员的安全.因此,研究CME及其驱动激波的形成机制和性质有利于我们更加清晰地了解及监测它们的运动过程,降低它们带来的灾害性空间天气的影响.本文主要以分析观测数据为主对不同CME事件及其驱动激波进行了多方面研究.

Coronal Mass Ejections(CMEs)are one of the most fierce explosion phenomena in the solar atmosphere.CMEs usually release a large amount of energy and eject massive magnetized plasma.CMEdriven shocks can further lead to solar energetic particle(SEP)events and affect the safety of spacecraft and astronauts.
