日冕漏斗中离子回旋波的射线追迹
Ray tracing of ion-cyclotron waves in a coronal funnel
摘要：
对日冕洞的远距离观测强烈暗示了离子回旋波与离子的动力学相互作用是等离子体加热和加速快速太阳风的主要机制。为了研究这些波，线性摄动分析中使用的无碰撞多流体模型的工作框架。我们考虑一个非均匀的背景等离子体描述的漏斗区域，并使用射线跟踪方程计算的射线路径的波，以及它们的属性的空间变化。
英文摘要：
Remote observations of coronal holes have strongly implicated the kinetic interactions of ion-cyclotron waves with ions as a principal mechanism for plasma heating and acceleration of the fast solar wind. In order to study these waves, a linear perturbation analysis is used in the work frame of the collisionless multi-fluid model. We consider a non-uniform background plasma describing a funnel region and use the ray tracing equations to compute the ray path of the waves as well as the spatial variation of their properties.
