Waves upstream of interplanetary shocks

2023
Interplanetary (IP) shocks can be driven in the solar wind by fast coronal mass ejections and by the interaction of fast solar wind with slow streams of plasma. These shocks can be preceded by extended waves and suprathermal ion foreshocks. Shocks characteristics as well as the level of wave activity near them change as they propagate through the ...

Interaction of interplanetary shocks with the bow shock

Planetary and Space Science, 2007
Abstract 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.

Coronal mass ejections and interplanetary shocks

Journal of Geophysical Research: Space Physics, 1985
A comparison between Solwind observations of coronal mass ejections (CME's) and Helios 1 observations of interplanetary shocks during 1979–1982 indicates that 72% of the shocks were associated with large, low‐latitude mass ejections on the nearby limb.

Interplanetary shock collisions: Forward with reverse shocks

Astrophysics and Space Science, 1986
When one interplanetary shock overtakes another, the structure that results depends upon the nature of the interacting shocks. We examine, numerically, the results of collisions of forward with reverse shocks, in two dimensions, and show that the results depend primarily upon shock strength.

Origin of strong interplanetary shocks

Nature, 1985
Observations of 900 radio sources have been used to study the shape and motion of large-scale interplanetary transients associated with shock disturbances at 1 AU. The variations of plasma density and speed and the zones in the solar atmosphere from which the transients originate suggest an origin related to intermittent flows of enhanced speed from ...

The evolution of interplanetary shocks

Journal of Geophysical Research: Space Physics, 1985
Unambiguous 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

Propagation of Interplanetary Shocks Across the Bow Shock

AIP Conference Proceedings, 2010
An 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 ...
