Abstract

We present the results of three-dimensional (3D) ideal magnetohydrodynamics (MHD) simulations on the dynamics of a perpendicularly inhomogeneous plasma disturbed by propagating Alfvénic waves. Simpler versions of this scenario have been extensively studied as the phenomenon of phase mixing. We show that, by generalizing the textbook version of phase mixing, interesting phenomena are obtained, such as turbulence-like behavior and complex current-sheet structure, a novelty in longitudinally homogeneous plasma excited by unidirectionally propagating waves. This study is in the setting of a coronal hole. However, it constitutes an important finding for turbulence-related phenomena in astrophysics in general, relaxing the conditions that have to be fulfilled in order to generate turbulent behavior.

摘要

我们展示了三维（3D）理想磁流体动力学（MHD）模拟的结果，该模拟研究了由传播的阿尔文波扰动的垂直不均匀等离子体的动力学。作为相位混合现象，此场景的简化版本已得到广泛研究。我们表明，通过推广教科书式的相位混合，可获得有趣的现象，如类似湍流的行为和复杂的电流片结构，这在由单向传播波激发的纵向均匀等离子体中是新颖的。本研究是在日冕洞的背景下进行的。然而，它总体上构成了天体物理学中与湍流相关现象的一个重要发现，放宽了为产生湍流行为而必须满足的条件。
