Numerical MHD Investigations of the Dynamical Correspondence of CMEs, Flares, Prominences, and Associated MHD Waves

摘要：ATM 00- 70385提案题目：CME、耀斑、日珥和相关MHD波动力学对应的数值MHD研究。T.吴，亚拉巴马大学，亨茨维尔研究人员将努力了解太阳日冕的几个大尺度特征，包括双峰磁场，太阳风结构，以及日冕物质抛射（CME），太阳耀斑和太阳耀斑之间的相互作用。主要的努力是采用二维（2D）轴对称和三维（3D）磁流体动力学（MHD）的数值代码来模拟这些观测到的日冕活动的功能。这项工作的一个独特方面是研究人员采用的方法来研究日冕的各种中尺度和大尺度特征之间的相互作用。研究的具体课题包括双峰风中的日冕物质抛射动力学和作为日冕活动与下面较致密色球层之间相互作用的莫尔顿波的研究。

Abstract: ATM 00-70385Proposal Title: Numerical MHD Investigations of the Dynamical Correspondence of CMEs, Flares, Prominences and Associated MHD WavesPrincipal Investigator: S. T. Wu, University of Alabama, Huntsville The investigators will work to understand several large scale features of the solar corona, including bi-modal magnetic fields, solar wind structure, and the interplay between coronal mass ejections (CME), solar prominences and solar flares. The main effort is to employ two-dimensional (2D) axisymmetric and three-dimensional (3D) magnetohydrodynamic (MHD) numerical codes to model these observed features of coronal activity. One unique aspect of the work is the approach adopted by the investigators to the interplay between various mesoscale and large-scale features of the corona. Specific topics of the research include CME dynamics in a bi-modal wind and study of Moreton waves as an interaction between coronal activity and the denser chromosphere beneath.
