Magnetosheath Structure in an Anisotropic Plasma Model
Astrophysics and Space Science, 2000Variations of the magnetic field and plasma parameters across the Earth's magnetosheath are calculated for an anisotropic plasma in the Chew-Goldberger-Low approximation. Additionally, proton pitch-angle diffusion is taken into account as the energy transfer mechanism between the direction perpendicular and parallel to the magnetic field.

Magnetosheath whistler turbulence
Journal of Geophysical Research: Space Physics, 1985Magnetic field short‐period fluctuations δB are observed throughout the earth's magnetosheath. We report a study of these fluctuations with frequencies 20 < f < 1000 Hz in which the turbulence has a broadband spectrum δB²(f) varying approximately as f−α, where α ∼ 4±0.5, or consists of a narrowband intermediate frequency peak superimposed on the ...

Magnetic fields of the magnetosheath
Reviews of Geophysics, 1976The magnetic field of the magnetosheath is most naturally discussed in terms of its steady state and its fluctuating components. The theory of the steady state field is quite well developed, and its essential features have been confirmed by observations.

Abstract We report a testing of the earlier developed in the Institute of Mechanics of the Bulgarian Academy of Sciences numerical data-based 3D model of the system magnetosphere–magnetosheath with real satellite data. The model is a result of a self-consistent solution of two tasks: (i) Chapman–Ferraro problem for an arbitrary 3D magnetopause with ...

A possibility of description of the properties of plasma flow in the magnetosheath using the INME hydrodynamical model is considered on the basis of a comparison with experimental data. This model is characterized by a high degree of self-consistency and, in particular, makes it possible to determine positions of the boundaries of the magnetosheath ...

MHD simulations of the magnetosheath
Advances in Space Research, 1994Ideal magnetohydrodynamic (MHD) simulations of the dayside magnetosheath are reported. The calculations show a depletion layer near the magnetopause and a new stagnation flow structure. The stagnation flow appears to be a generalization of the stagnation line for ideal MHD.

Abstract A review is given of the author's two decades of magnetosheath modeling work with John Spreiter Beginning in the early 1970s, a sequence of computational magnetosheath submodels that extended and refined John's basic model were developed and successfully applied to virtually every planet in the solar system including the terrestrial planets ...
