Overshoots in planetary bow shocks

Nature, 1982
The parametric variation with solar wind conditions in the overshoot in magnetic field strength observed in planetary bow shocks and believed to be associated with the ion reflection process is examined based on both terrestrial and planetary bow shock data.

Plasma wave turbulence at planetary bow shocks

Nature, 1981
Voyager 1 observations of plasma wave turbulence at Saturn's bow shock are discussed and compared with corresponding data from Jupiter, earth, and Venus. The results suggest that the plasma instabilities that develop at the lower Mach number bow shocks of the terrestrial planets differ from those found at the high Mach number bow shocks of the outer ...

Particle acceleration at planetary bow shock waves

Nature, 1982
We can extend our understanding of collisionless shocks by comparing their behaviour in a variety of plasma conditions at several different planets. One property of such shocks is the occurrence of upstream magnetohydrodynamic waves associated with particle beams accelerated at these shocks, and flowing back towards the Sun1.

Heliospheric shocks (excluding planetary bow shocks)

Reviews of Geophysics, 1987
Even 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 nature of ULF waves upstream of planetary bow shocks

Advances in Space Research, 1981
The ULF electromagnetic waves associated with the earth's foreshock appear in two discrete frequency ranges, designated the low frequency waves at 0.01 - .05 Hz and the high frequency waves at 0.4 - 1.0 Hz. Falling within this second class are both the 0.4 Hz discrete wave packets and the slightly higher frequency wave trains commonly found just ...

Upstream whistler-mode waves at planetary bow shocks: A brief review

Journal of Atmospheric and Solar-Terrestrial Physics, 2007
Upstream whistler-mode waves appear to be present in front of all collisionless shocks. Because the whistler-mode group velocity exceeds its phase velocity over the frequency range in which the phase velocity increases with frequency, interesting alterations of polarization and frequency spectrum occur in the observer's reference frame.

A comparative analysis of terrestrial and planetary bow shocks

2011 XXXth URSI General Assembly and Scientific Symposium, 2011
Collisionless shocks, such as the Earth bow shock, are very spectacular and energetic events in the Universe. For instance, generated by supernovae, stellar winds, and the solar wind collisonless shock have important effects. They are considered to be efficient particle accelerators and they act galactic nebula and therefore they are considered to ...
