ULF Magnetic Pulsations in Southern Hemisphere with Kinetic Alfv 6 n Waves

چکیده

The main goal of this paper is to study the Ultra Low Frequency-UlF magnetic pulsatrons (magnetic micropulsations) in the magnetosphere due to disturbances produced possibly by different mechanisms such as magnetic storms and/or substorms, energetic electron beams and so on. These pulsations are seen as electromagnetic ion cyclotron/kinetic Alfv6n waves with a broad spectrum of frequencies, in contrast with the very well known Kelvin-Helmoltz mode conversion that excites monochromatic magnetospheric magnetic pulsations. Here our interest is to relate the continue micropulsations data in the range of 0.2 s to 600 s, with the kinetic/fast Alfv6n waves in the region of the Earth magnetosphere.

Dissipation Range Dynamics : Kinetic Alfv en Waves andthe Importance of eRobert

In a previous paper we argued that the damping of obliquely propagating kinetic Alfv en waves, chieey by resonant mechanisms, was a likely explanation for the formation of the dissipation range for interplanetary magnetic eld uctuations. This suggestion was based largely on observations of the dissipation range at 1 AU as recorded by the Wind spacecraft. We pursue this suggestion here with both...

Alfv En Wave Solitons and Solar Intermediate Drift Bursts

We investigate stationary solutions for Alfv en solitons propagating obliquely in a homogeneous magnetic eld. Due to their dispersive nature kinetic Alfv en waves can evolve into soliton like structures which propagate at velocities of the order of the Alfv en velocity in a direction inclined to the magnetic eld. In the rst model we keep the plasma < m e =m i. Kinetic Alfv en solitons in this c...

Electrostatic broadband ELF wave

The linear and nonlinear kinetic properties of electrostatic oblique waves below the lower hybrid frequency are investigated. For propagation angles # = k k =k ? < q m e =m i the waves are damped by either parallel electron Landau or ion cyclotron damping. For T i =T e 1 the waves are only weakly damped and can propagate. These waves are called slow ion cyclotron (SIC) and slow ion acoustic (SI...

Laboratory Experiments on Shear Alfvn Waves, and their Relationship to Space Plasmas

AlfvŽn waves are ubiquitous in space plasmas and are the means by which information about changing currents and magnetic fields are communicated. Shear AlfvŽn waves radiated from sources with cross field scale size on the order of the electron inertial length, δ = c/ωpe, have properties which differ considerably from planar Magneto-hydrodynamic waves. Currents of cross field size , δ, are commo...

Preprint: Alfv¶en Wave Instability of Current Sheets in Force-Free Collisionless Plasmas

If the current sheet between adjacent twisted magnetic °ux tubes is suf̄ciently thin, the electron °ow velocity becomes comparable to the Alfv¶en velocity and can destabilize collisionless Alfv¶en waves. The threshold for instability in force-free plasmas is calculated for both inertial and kinetic Alfv¶en wave regimes. When there is strong magnetic shear, unstable kinetic Alfv¶en waves can reso...
