Acceleration of an interplanetary shock through the magnetosheath: a global hybrid simulation
According to most observations and simulations, interplanetary shocks slow down when they propagate through the magnetosheath. In this article, we present results from a self-consistent global hybrid PIC simulation of an interplanetary shock which, by ...

Drift acceleration at interplanetary shocks [PDF]
AbstractScatter-free acceleration of energetic particles by quasi-perpendicular interplanetary shocks is investigated. A brief review is given on the predictions of the gradient drift acceleration model concerning the energy, time, and angular dependence of the particle flux caused by a single shock encounter interaction.

Particle Acceleration at Interplanetary Shocks [PDF]
This paper briefly reviews proton acceleration at interplanetary shocks. This is key to describing the acceleration of heavy ions at interplanetary shocks because wave excitation—and hence particle scattering—at oblique shocks is controlled by the protons and not the heavy ions.

CLASSIFICATION OF THE INTERPLANETARY SHOCKS BY SHOCK DRIVERS [PDF]
From the data of solar wind observation by ACE spacecraft orbiting the Earth-Sun Lagrangian point, we selected 48 forward interplanetary shocks(IPSs) occurred in 2000, maximum solar activity period. Examining the profiles of solar wind parameters, the IPSs are classified by their shock drivers.

Interaction between an interplanetary shock and the geomagnetic frontiers: Hybrid PIC simulations
International audienceIn the hybrid PIC code LatHyS - which is used to simulate the interaction between the solar wind and planetary magnetic environments - we injected a fast magnetic cloud which self consistently leads to the formation of an ...

Interaction of a strong interplanetary shock with the termination shock [PDF]
The 1991 global merged interaction region (GMIR) shock is a strong forward shock observed from Voyager 2 on day 146 of 1991 at 34.6 AU. As the GMIR shock propagated out‐ward in the distant heliosphere, it eventually encounters the termination shock. We study the interaction of the GMIR shock with the termination shock taking into account the influence ...

Cassini encounters with hot flow anomaly-like phenomena at Saturn's bow shock [PDF]
The first observations of the kronian equivalent of hot flow anomalies (HFAs) are presented. Using magnetic field and plasma data we discuss two events that were observed upstream of Saturn's bow shock during the first two orbits of the Cassini ...

Unusual enhancement of ~ 30 MeV proton flux in an ICME sheath region
In gradual Solar Energetic Particle (SEP) events, shock waves driven by coronal mass ejections (CMEs) play a major role in accelerating particles, and the energetic particle flux enhances substantially when the shock front passes by the observer.

Statistical study on interplanetary drivers behind intense geomagnetic storms and substorms
Geomagnetic storms and substorms play a central role in both the daily life of mankind and in academic space physics. The profiles of storms, especially their initial phase morphology and the intensity of their substorms under different interplanetary ...

Sources of interplanetary shocks [PDF]
Abstract The sources of interplanetary shocks are reviewed from the standpoint of today's knowledge. Recent progress from both new and accumulated observations and models indicates that contributions from the two major sources of the shocks: CMEs and stream interactions, have distinctive radial, latitudinal and temporal dependencies.
