Observation of a Dual Reconnection Exhaust Inside the Boundary Layer of Magnetic Cloud at 1 AU

  • 摘要: 太阳风中的磁场重联通常与行星际日冕物质抛射有关.本文分析了1995年10月18日WIND飞船观测到的一例磁云前边界层中的复合重联喷流事件.该复合排空区由相邻两个不同方向的喷流构成,这两个喷流分别经过Walén关系的证认,符合行星际磁场重联排空区等离子体喷流的特征.结果表明,在磁云前端可能存在众多重联点,从而将磁云本体的磁场剥离,形成比单一重联喷流区更复杂的三维边界层结构.磁云边界层中可能发生多点多次重联,从而不表现出单点重联的排空区特征,这可能是行星际磁场重联排空区较少在ICME前端被观测到的原因之一.
