Observations of interplanetary shocks: Recent progress
Space Science Reviews, 1983Interplanetary shock observations since the prior Solar Terrestrial Physics Symposium in 1978 are reviewed. Since the interval coincides with the recent solar maximum, emphasis is placed on shocks associated with transient solar phenomena, including coronal transients and eruptive prominences as well as flares.

Voyager Observations of Interplanetary Shocks
AIP Conference Proceedings, 2005Data from Voyager 2 are used to compile a shock catalogue covering the 27 years of Voyager 2 solar wind data through the end of 2004. This catalogue is used to investigate the characteristics of shocks as a function of distance out to 75 AU. The shock occurrence frequency decreases with distance.

The evolution of interplanetary shocks
Journal of Geophysical Research: Space Physics, 1985Unambiguous identification of the solar events associated with 48 interplanetary (IP) shocks has been facilitated by the observation of radio emission generated by the shocks. This identification makes possible an investigation of the way in which these shocks evolve and of the relationship between solar event “strength” and shock velocity. All but two

Interaction of interplanetary shocks with the bow shock
Planetary and Space Science, 2007Abstract Fast forward interplanetary (IP) shocks have been identified as a source of large geomagnetic disturbances. However, the shocks can evolve in the solar wind, they are modified by interaction with the bow shock and during their propagation through the magnetosheath.

1991
Ever since the identification of the first interplanetary shock wave from the Mariner 2 plasma and magnetic field measurements [7.38], shock research has received great attention in solar system plasma physics, and this has resulted in an outstanding collaboration between laboratory and space experimentalists, theorists, and specialists in numerical ...

Evolution of interplanetary slow shocks
Journal of Geophysical Research: Space Physics, 1988The possible existence of traveling forward slow shocks, their global geometry and their transition to forward fast shocks have been discussed in a recent paper. The decrease in the Alfven speed at increasing heliocentric distance causes the evolution of a forward slow shock into a forward fast shock.

Mass-loading at interplanetary shocks
Physics of Fluids B: Plasma Physics, 1992The interaction of the solar wind with the atmospheres of nonmagnetized and weakly magnetized bodies, such as found at comets and the planets Venus and Mars, is currently an area of great interest in space plasma physics. Photoionization of the atmospheric coma surrounding a comet or a weakly magnetized planet leads to ‘‘mass-loading’’ of the impinging

Propagation of Interplanetary Shocks Across the Bow Shock
AIP Conference Proceedings, 2010An important problem of the Space Weather Program is the interaction of interplanetary (IP) shocks with the Earth magnetosphere because their interaction often (but not always) leads to major geomagnetic storms. Since the huge interaction region can be covered by simultaneous spacecraft observations only sporadically, global MHD modeling can help in ...

Waves observed upstream of interplanetary shocks
Journal of Geophysical Research: Space Physics, 1983The properties of waves with frequencies below 3 Hz observed upstream of low Mach number (2–3) interplanetary shocks are discussed. High‐frequency emissions (0.2–2 Hz in the spacecraft frame) are commonly detected immediately upstream (<2 RE) of the shocks, whereas lower frequency emissions (∼0.05 Hz) are found to extend upstream to much greater ...

Multi-Spacecraft Observations of Interplanetary Shocks
2022<div> <p>Interplanetary (IP) shocks provide us with a unique opportunity to extensively investigate properties of collisionless shocks using in situ measurements under a wide range of upstream conditions. Here we report a case study of several IP shock crossings observed by the Wind, Solar and Heliospheric Observatory (SOHO),
