Imbalanced Weak Magnetohydrodynamic Turbulence
WeakMHD turbulence consists of waves that propagate along magnetic field lines, in both directions. When two oppositely directed waves collide, they distort each other, without changing their respective energies. Each wave suffers many collisions before cascading; by contrast, in strong MHD turbulence, waves cascade on the same timescale at which they collide. ‘‘ Imbalance ’’ means that more en...
متن کاملStrong Imbalanced Turbulence
We consider stationary, forced, imbalanced, or cross-helical MHD Alfvénic turbulence where the waves traveling in one direction have higher amplitudes than the opposite waves. This paper is dedicated to so-called strong turbulence, which cannot be treated perturbatively. Our main result is that the anisotropy of the weak waves is stronger than the anisotropy of a strong waves. We propose that c...
متن کاملAcceleration of particles in imbalanced magnetohydrodynamic turbulence.
The present work investigates the acceleration of test particles, relevant to the solar-wind problem, in balanced and imbalanced magnetohydrodynamic turbulence (terms referring here to turbulent states possessing zero and nonzero cross helicity, respectively). These turbulent states, obtained numerically by prescribing the injection rates for the ideal invariants, are evolved dynamically with t...
متن کاملImbalanced Strong Mhd Turbulence
We present a phenomenological model of imbalanced MHD turbulence in an incompressible magnetofluid. The steady–state cascades, of waves traveling in opposite directions along the mean magnetic field, carry unequal energy fluxes to small length scales, where they decay due to viscous and resistive dissipation. The inertial–range scalings are well–understood when both cascades are weak. We study ...
متن کاملImbalanced Relativistic Force-free Magnetohydrodynamic Turbulence
When magnetic energy density is much larger than that of matter, as in pulsar/black hole magnetospheres, the medium becomes force-free and we need relativity to describe it. As in non-relativistic magnetohydrodynamics (MHD), Alfvénic MHD turbulence in the relativistic limit can be described by interactions of counter-traveling wave packets. In this paper we numerically study strong imbalanced M...
