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

摘要：题目：数值MHD研究日冕、耀斑、日珥和相关MHD波的动力学对应关系主要研究者：s.t. Wu, University of Alabama, Huntsville。研究人员将致力于了解太阳日冕的几个大尺度特征，包括双模态磁场、太阳风结构以及日冕物质抛射（CME）、日珥和太阳耀斑之间的相互作用。主要工作是采用二维轴对称和三维磁流体动力学数值代码来模拟这些观测到的日冕活动特征。这项工作的一个独特方面是研究人员对日冕的各种中尺度和大尺度特征之间的相互作用所采用的方法。研究的具体主题包括双峰风中的CME动力学和作为日冕活动与其下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.
