项目摘要

The Solar Physics and Space Plasma Research Centre (SP2RC) at the University of Sheffield seeks to understand the nature of key plasma processes occurring in the solar interior and the atmosphere of the Sun, from photosphere to corona, with particular attention devoted to the various coupling mechanisms of these apparently distinct regions. A large part of the energy flux released in the solar atmosphere travels into interplanetary space and impacts on the Earth's bow shock, energising the magnetosphere and having impact of our daily human life. The generation of energetic events in the convection zone and their propagation through the solar interior-atmosphere-space plasma system will be investigated by using mathematical modelling and the analysis of latest available satellite and ground-based datasets. Our mathematical approach involves rigorous analytical work and the implementation of parallel computing (GRID technology) where results will be tested and verified by making and using space (SOHO, TRACE, Hinode, COROT, SDO) and ground-based (Swedish Solar Telescope, Dunn Solar Telescope) observations. The proposed programme involves three Themes: 1) Structure and dynamics of the solar interior and other stars; 2) Heating and magneto-seismology of the solar atmosphere; and 3) Instabiltities of geophysical and astrophysical flows. We request funding to cover salaries of the RAs, appropriate costs for research management and research time for the Principal Investigator and five Co-Investigators, funding for four special PhD studentship in order to train the future generation experts of the field, funding for our visitor programme, for travel & subsistence, computing equipment and consumables.

谢菲尔德大学的太阳物理学和空间等离子体研究中心（SP2 RC）力求了解发生在太阳内部和太阳大气层（从光球层到日冕）的关键等离子体过程的性质，特别关注这些明显不同的区域的各种耦合机制。太阳大气层中释放的大部分能量通量进入行星际空间，并影响地球的弓形激波，为磁层提供能量，并对我们的日常生活产生影响。将利用数学建模和对现有最新卫星和地面数据集的分析，研究对流区高能事件的产生及其通过太阳走廊-大气层-空间等离子体系统的传播。我们的数学方法涉及严格的分析工作和并行计算（网格技术）的实施，其中结果将通过制作和使用空间（SOHO，TRACE，Hinode，COROT，SDO）和地面（瑞典太阳望远镜，Dunn太阳望远镜）观测进行测试和验证。拟议的方案涉及三个主题：1）太阳内部和其他恒星的结构和动力学; 2）太阳大气层的加热和磁震学; 3）地球物理和天体物理流动的不稳定性。我们要求资金支付RA的工资，主要研究者和五名合作研究者的研究管理和研究时间的适当费用，为四名特殊博士生提供资金，以培训该领域的未来一代专家，为我们的访问者计划提供资金，用于旅行和生活费，计算设备和消耗品。
