Solar Magneto-Convection Simulations

摘要：题目：太阳磁对流模拟项目项目负责人：Robert Stein，密歇根州立大学研究人员将致力于提高密歇根州立大学研究小组的能力，以继续对太阳外层发生的几个过程进行最新的研究。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。这将大大提高模拟的速度，以便在更大的容量上运行更长时间。反过来，这减少了初始条件的影响，并允许对高度分层的太阳等离子体进行更现实的处理，受磁场（整个体积）和辐射传输（在顶层）的影响。在太阳p模、近地表对流、小尺度和/或弱磁场观测能力快速发展的时代，这项研究是非常及时的。该项目将填补对数值模拟的迫切需要，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.
