The modified plasma dispersion function
Danny Summers,Richard M. Thorne +1 more
TL;DR: The modified plasma dispersion function (MPDF) as mentioned in this paper is based on the generalized Lorentzian (kappa) particle distribution function, and a comprehensive set of graphs of the real and imaginary parts of the MPDF is presented.

Magnetosphere-ionosphere coupling
C. K. Goertz,R. W Boswell +1 more
TL;DR: In this article, a simple two-dimensional model of the magnetosphere-ionosphere system is discussed in which a localized electromotive force applied across a magnetic field line at t = 0 is shown to propagate along the magnetic field with the Alfven velocity.

Satellite measurements and theories of low altitude auroral particle acceleration
TL;DR: In this article, the S3-3 satellite results on DC electric fields, field-aligned currents, and waves are described, interpreted theoretically, and applied to the understanding of auroral particle acceleration at altitudes below 8000 km.

Nonlocal stability analysis of the MHD Kelvin‐Helmholtz instability in a compressible plasma
Akira Miura,P. L. Pritchett +1 more
TL;DR: In this paper, the stability of sheared MHD flow of finite thickness in a compressible plasma was analyzed for the case of arbitrary orientation of the magnetic field, velocity flow, and wave vector in the plane perpendicular to the velocity gradient.

Self‐consistent particle and parallel electrostatic field distributions in the magnetospheric‐ionospheric auroral region
Y. T. Chiu,Michael Schulz +1 more
TL;DR: In this paper, the variation of the selfconsistent electrostatic potential along the magnetic field is calculated by application of the principle of quasi-neutrality to the plasma components distributed along an auroral field line.

Dissipation of Currents in Ionized Media
TL;DR: In this article, the fastest stable drift was calculated (drift energy $0.9kT$) and the energy of a faster drift was found to be dissipated into instabilities within, typically, 30 plasma periods.

Longitudinal Ion Oscillations in a Hot Plasma
Burton D. Fried,Roy W. Gould +1 more
TL;DR: In this article, a Vlasov equation description of the plasma is used to explore the properties of longitudinal waves in a hot plasma, including electron and ion plasma oscillations, which are not likely to be observable due to their strongly damped properties.
Journal ArticleDOI
Anomalous Diffusion Arising from Microinstabilities in a Plasma
TL;DR: In this article, the authors considered a plasma in which a Maxwellian distribution of electrons with thermal velocity ve and drift velocity vD is drifting relative to a MIMO distribution of ions with thermal velocities vi and thermal velocity vi, where the usual ion acoustic waves are stable, however, electrostatic ion cyclotron waves with ω ≅ Ωi are unstable.

High-latitude plasma transport: The polar wind
Peter M. Banks,Thomas E. Holzer +1 more
TL;DR: Plasma transport models of polar ionosphere, discussing physical processes involved and effects on electron concentration, ion composition and speeds were discussed in this paper, where the authors also discussed the physical process involved and the effects of electron concentration and ion composition.

Resonance in a Plasma with Two Ion Species
TL;DR: In this paper, the effect of varying the relative concentration of the two ions is discussed, and it is shown that collisions between the two ion clouds randomize the large ordered velocities of the ions with great efficiency.
