Recent progress in astrophysical plasma turbulence from solar wind observations

This paper summarises some of the recent progress that has been made in understanding astrophysical plasma turbulence in the solar wind, from in situ spacecraft observations. At large scales, where the turbulence is predominantly Alfvenic, measurements of critical balance, residual energy, and 3D structure are discussed, along with comparison to recent models of strong Alfvenic turbulence. At these scales, a few percent of the energy is also in compressive fluctuations, and their nature, anisotropy, and relation to the Alfvenic component is described. In the small scale kinetic range, below th…

Nonlinear evolution of short-wavelength torsional Alfven waves

We analyse nonlinear evolution of torsional Alfvén waves in a straight magnetic flux tube filled in with a low-$β$ plasma, and surrounded with a plasma of lower density. Such magnetic tubes model, in particular, a segment of a coronal loop or a polar plume. The wavelength is taken comparable to the tube radius. We perform numerical simulation of the wave propagation using ideal magnetohydrodynamics. We find that a torsional wave nonlinearly induces three kinds of compressive flows: the parallel flow at the Alfvén speed, that constitutes a bulk plasma motion along the magnetic field, the tube w…

Kinetic Alfvén solitary and rogue waves in superthermal plasmas

本文研究了低$β$等离子体中的小但有限振幅的动力学Alfvén孤立波。利用标准约化摄动法导出了描述KAWs演化的非线性KdV方程。研究了KdV方程的非线性系数和色散系数对超热参数$κ$、等离子体$β$和传输的非线性度的依赖关系，表明这些参数可以显著改变KAW孤立脉冲的形状和大小。只支持亚阿尔夫文孤子，压缩孤子。然后，我们通过从{KdV}方程推导出非线性薛定谔方程来研究动力学Alfvén流氓波。得到了形成异常波包络的有理解。我们研究流氓波的行为如何取决于等离子体参数的问题，发现流氓信封降低电子超热性的增加，而相反的是真实的等离子体$β$增加。这项研究的结果可能会发现应用程序的低$β$等离子体在天体物理环境中的粒子是超热分布。
