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.

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),

Interplanetary shock waves: Recent developments
Space Science Reviews, 1975Direct and indirect observations of interplanetary shock waves have been extended to the study of (i) the shock structure itself; (ii) the disturbed solar wind in its wake; (iii) additional discontinuities such as reverse shocks and pistons; and (iv) the shock's kinematic behavior.

Suprathermal ions upstream from interplanetary shocks
Journal of Geophysical Research: Space Physics, 1984Suprathermal ions with energies between solar wind thermal energies and ∼29 keV are occasionally observed ahead of outward propagating interplanetary shocks with the Los Alamos/Garching fast plasma experiment on ISEE 1 and 2. Compared with suprathermal ion velocity distributions observed upstream from the earth's bow shock, the upstream interplanetary ...

Flare-Produced Interplanetary Shock Waves
1972The occurrence of geomagnetic storms one to several days after some prominent solar flares has long been attributed to arrival at the earth of material ejected by the flare. Consider a volume of this material, presumably plasma from the chromosphere or low corona, moving rapidly outward into a slower ambient solar wind (such as already shown in Fig.
