This research program is primarily a theory oriented study of waves in the magnetosheath and on the surface of the magnetopause. The program will also examine the role similar MHD waves play in coronal heating on the sun. The approach used will be primarily theoretical studies of MHD wave activity, and in particular the emphasis will be on Kinetic Alfven waves (KAW). The theoretical results will be compared with observed wave amplitudes and polarizations as a function of magnetic shear and magnetic field gradients.

本研究计划主要是对磁鞘和磁层顶表面的波动进行理论研究。 该计划还将研究类似的MHD波在太阳日冕加热中的作用。 所采用的方法将主要是MHD波活动的理论研究，特别是重点将是动力阿尔芬波（KAW）。 理论结果将与观测到的波的振幅和极化作为磁剪切和磁场梯度的函数进行比较。
