Solar Magneto-Convection Simulations

摘要：ATM 99-88111建议标题：太阳磁对流模拟首席研究员：密歇根州立大学罗伯特·斯坦研究人员将努力提高密歇根州立大学研究小组继续对太阳外层发生的几个过程进行最先进研究的能力。主要的努力是资助一名博士后研究人员专注于并行化现有的计算机代码。这将极大地提高模拟的速度，以便在更大的体积上运行更长的时间。反过来，这减少了初始条件的影响，并允许更现实地处理高度分层的太阳等离子体，受到磁场(整个体积)和辐射传输(在顶层)的影响。在一个研究太阳p模、近地表对流以及小尺度和/或弱磁场的观测能力迅速进步的时代，这项研究是非常及时的。该项目将满足对数值模拟的迫切需求，以测试和加深对这些现象的物理理解。

Abstract: ATM 99-88111Proposal Title: Solar Magneto-Convection SimulationsPrincipal Investigator: Robert Stein, Michigan State University The investigators will work to enhance the ability of the research group at Michigan State University to continue state of the art research on several processes occurring in the outer layers of the Sun. The main effort is to fund a postdoctoral researcher to concentrate on parallelizing existing computer codes. This will vastly increase the speed of simulations to allow longer runs on larger volumes. In turn, this reduces effects of initial conditions and allows a more realistic treatment of the highly stratified solar plasma, subject to magnetic fields (throughout the volume) and radiative transfer (in the top layers). This research is extremely timely in an era of rapid advances in observational abilities to study solar p-modes, near-surface convection, and small-scale and/or weak magnetic fields. The project will fill an urgent need for numerical simulations to test and deepen the physical understanding of these phenomena.
