Applications of Radiative Magnetohydrodynamics to Numerical Simulations of the Solar Wind in the Inner Heliosphere
摘要
Abstract
We present a brief overview of the applications of radiative magnetohydrodynamics (RMHD) to the numerical simulations of the solar wind in the inner heliosphere. How the solar wind originates on the Sun is at the heart of solar wind studies, and is also among the primary scientific objectives of international space missions to be launched in the coming years. We start with a brief introduction to the consensus on the origins of the solar wind, thereby showing that the acceleration of the nascent solar wind is very likely to be a direct result of coronal heating in magnetically open regions. We then briefly overview some essential physical and mathematical ingredients in current numerical models of the solar wind. An outcome of this overview is that radiation needs to be carefully addressed to self-consistently account for the wind thermodynamics. With some illustrative examples we show how radiation is handled in current multi-dimensional solar wind models. We conclude this manuscript with a brief discussion on the prospects of incorporating radiation effects more self-consistently in solar wind models.关键词
