In the present Rolling Grant application the Solar and Magnetospheric Theory Group (SMTG) of the University of St Andrews asks for funding to investigate fundamental physical processes occurring in the solar atmosphere and the magnetosphere. The research topics we want to investigate using plasma theory are: i) the emergence of new magnetic flux through the solar surface into the solar atmosphere, ii) the use of MHD waves to deduce properties of the coronal plasma and magnetic field (coronal seismology), iii) the physical mechanisms which keep the corona much hotter than the lower parts of the solar atmosphere (coronal heating), iv) magnetic reconnection, a process of extreme importance for energy release of magnetised plasmas, v) solar flares and coronal mass ejections, which are the most powerful manifestations of solar magnetic activity and vi) the physics of ultra-low frequency waves in the Earth's magnetosphere and how they contribute to the acceleration of electrons causing the aurora.

在目前的滚动拨款申请中，圣安德鲁斯大学的太阳和磁层理论小组（SMTG）请求资金来研究太阳大气和磁层中发生的基本物理过程。我们想要使用等离子体理论研究的研究主题是：i）通过太阳表面进入太阳大气的新磁通量的出现，ii）使用MHD波来推断日冕等离子体和磁场的特性（日冕地震学），iii）使日冕比太阳大气下部更热的物理机制（日冕加热），iv）磁重联，一个极端的过程 磁化等离子体能量释放的重要性，v) 太阳耀斑和日冕物质抛射，这是太阳磁活动最强大的表现形式，vi) 地球磁层中超低频波的物理原理以及它们如何促进电子加速，从而导致极光。
