Solar and Magnetospheric Plasma Theory

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）要求资助研究太阳大气和磁层中发生的基本物理过程。我们想利用等离子体理论研究的课题有：i)通过太阳表面进入太阳大气的新磁通量的出现，ii)利用MHD波推断日冕等离子体和磁场的性质（日冕地震学），iii)使日冕比太阳大气下部温度高得多的物理机制（日冕加热），iv)磁重联，一个对磁化等离子体能量释放极其重要的过程，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，以及vi)地球磁层中超低频波的物理学，以及它们如何促进电子的加速，从而产生极光。

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.
