摘要

本文提出了一个磁流体动力学模型，描述了在相对论性强平均磁场存在的情况下，波长与离子惯性长度相当的小振幅波动。推导出的方程组与非相对论霍尔还原磁流体动力学（Schekochihin 等，J. Plasma Phys.，第 85 卷，2019 年，905850303）几乎完全相同，区别仅在于考虑了相对论修正的几个常数。这意味着非相对论霍尔机制中固有的动力学阿尔芬湍流和离子回旋湍流的所有特性即使在磁主导机制中也保持不变。

Hall magnetohydrodynamics in a relativistically strong mean magnetic field

This paper presents a magnetohydrodynamic model that describes the small-amplitude fluctuations with wavelengths comparable to ion inertial length in the presence of a relativistically strong mean magnetic field. The set of derived equations is virtually identical to the non-relativistic Hall reduced magnetohydrodynamics (Schekochihin et al., J. Plasma Phys., vol. 85, 2019, 905850303), differing only by a few constants that take into account the relativistic corrections. This means that all the properties of kinetic Alfvén turbulence and ion cyclotron turbulence inherent in the non-relativistic Hall regime persist unchanged even in a magnetically dominated regime.

期刊介绍： JPP aspires to be the intellectual home of those who think of plasma physics as a fundamental discipline. The journal focuses on publishing research on laboratory plasmas (including magnetically confined and inertial fusion plasmas), space physics and plasma astrophysics that takes advantage of the rapid ongoing progress in instrumentation and computing to advance fundamental understanding of multiscale plasma physics. The Journal welcomes submissions of analytical, numerical, observational and experimental work: both original research and tutorial- or review-style papers, as well as proposals for its Lecture Notes series.
