AST 0205500PI SteinThere has been significant progress in recent years in our understanding of the physics of the Sun. In particular the structure of the sun is being revealed from detailed observations of the solar surface layers and their motions. In a sense the Sun is a giant echo chamber and careful analysis of all the solar resonant modes and wave propagation properties tells us what the interior is like. In this research realistic numerical simulations of the interaction between convection in the outer solar layers, magnetic fields, and the acoustic oscillations will be carried out to aid our understanding of the solar interior. The project will extend our knowledge by studying small scale magnetic fields produced 'locally' and their role in the formation of supergranulation at the solar surface. The results will be applied to present solar observations and will provide guidance to the design of the next generation of high spatial and temporal resolution solar telescopes.

斯坦近些年来，我们对太阳物理的理解有了很大的进步。特别是，通过对太阳表面层及其运动的详细观察，太阳的结构正在被揭示。从某种意义上说，太阳是一个巨大的回音室，仔细分析所有的太阳共振模式和波传播特性，就能告诉我们太阳内部是什么样子的。在这项研究中，将对太阳外层对流、磁场和声学振荡之间的相互作用进行逼真的数值模拟，以帮助我们了解太阳内部。该项目将通过研究“局部”产生的小尺度磁场及其在太阳表面超颗粒形成中的作用来扩展我们的知识。该成果将应用于目前的太阳观测，并将为下一代高空间和时间分辨率太阳望远镜的设计提供指导。
