Magnetohydrodynamic aspects of the Earth’s bow shock 1. Equilibrium bow shock position
Journal of Geophysical Research, 1974The fluid dynamic treatment of the magnetosphere-bow shock system provides a useful means to calculate the equilibrium standoff distance of the shock. From the simple gas dynamic model a specific heat ratio γ≈5/3 of the streaming plasma is found to be appropriate for average solar wind conditions.

Planetary bow shocks provide insight into both the behavior of collisionless shocks and the nature of the planetary obstacle responsible for creating those bow shocks. This review paper first presents a survey of the microstructure of planetary bow shocks using data obtained at Mercury, Venus, the earth, Mars, Jupiter, and Saturn.

Asymmetric reconnection at the bow shock
2020<p>Can reconnection be triggered as a directional discontinuity (DD) crosses the bow shock? Here we present some unique observations of asymmetric reconnection at a quasi-perpendicular bow shock as an interplanetary DD is crossing it simultaneously with the Magnetospheric Multiscale (MMS) mission.

Voyager 2 crossed the inbound or upstream Neptunian bow shock at 1430 spacecraft event time on August 24 in 1989 (Belcher et al., 1989). The plasma and magnetic field measurements allow us to study the solar wind interaction with the outermost gas giant.

Bow shock and its interaction with interplanetary shocks
Radio Science, 1973Harbingers of significant magnetospheric motions consist of the interactions of interplanetary discontinuities with the standing bow shock. The most common discontinuity is the tangential discontinuity. Less frequent in occurrence, but of major significance to subsequent magnetospheric dynamics, is the flare‐generated interplanetary shock wave and its ...

Decay of the cometary bow shock
Nature, 1985Cooling processes will weaken the bow shock that is expected to form when the solar wind plasma encounters a gassy comet. As the supersonic wind penetrates the comet's outer coma, accreting freshly ionized cometary atoms and molecules, it needs a shock to adjust to the inner subsonic conditions.

Heliospheric shocks (excluding planetary bow shocks)
Reviews of Geophysics, 1987Even though it took place less than halfway through the last four year period, the AGU Chapman Conference in Napa Valley, California, during February, 1984, highlighted in many ways current U. S. contributions to the study of heliospheric shocks. Considerable recent progress in the theoretical understanding of these discontinuities has been summarized ...

On the structure of the turbulent bow shock
Journal of Geophysical Research, 1973A few short bow shock crossings have been studied (Days 44, 53, 255, and 48, 1969). The first three events are shown to be incomplete shock crossings; i.e., the satellite spent a few minutes each time within the shock layer. Large-amplitude waves are observed in |B| with frequency close to Ωi.

The Structure of the Earth’s Bow Shock
1972The investigation which we shall briefly describe is an attempt to shed light on the structure of the earth’s bow shock wave. Unlike gas dynamic shocks col-lisionless plasma shocks can dissipate directed flow energy in a number of different ways. In some of the models the shock structure is governed by plasma-magnetic field interaction (Kennel and ...

A model for a strong plasma shock wave with a structure determined by ion wave instabilities has been developed. The magnetic field structure of the shock wave is further investigated and found to have many features in agreement with satellite observations of the earth's bow shock.
