项目摘要
Project Summary Lou/ATM-9320357 This project will focus on magnetohydrodynamic physical processes likely to be involved in solar chromospheric and coronal activity. The research is a continuation of past efforts to understand the mechanisms by which waves generated in the convective zones of stars propagate into the magnetized outer atmospheric layers, and the physical effects arising from this wave propagation. Specific goals of this continuation are: (1) to model the extended heating of the inner solar wind via resonant absorption of Alfven waves; (2) to construct analytical models for the reflection and transmission of Alfven waves in inhomogeneous atmospheres, all outside the WKB approximation; and (3) to develop numerical experiments for the simulation of both resonant absorption and reflection of Alfven waves, and compare results from these experiments to the analytical results.
项目摘要LOU/ATM-9320357该项目将侧重于可能涉及太阳、色球和日冕活动的磁流体动力学物理过程。这项研究是对过去努力的继续,目的是了解恒星对流区产生的波传播到磁化外层大气层的机制,以及这种波传播产生的物理影响。本系列的具体目标是:(1)通过对Alfven波的共振吸收来模拟内太阳风的扩展加热;(2)构建Alfven波在非均匀大气中的反射和传输的分析模型,所有这些都在WKB近似之外;以及(3)为模拟Alfven波的共振吸收和反射开展数值实验,并将这些实验的结果与分析结果进行比较。
