Magnetic Cloud and Its Interplanetary Shock Sheath as a Modulator of the Cosmic Ray Intensity [PDF]
Journal of Astronomy and Space Sciences, 2008 Forbush Decreases (FDs) are representative events of abrupt decrease in galactic cosmic ray intensity. They are known to be strongly associated with solar wind events such as interplanetary shock (IP shock) and magnetic cloud (MC).

Interpretation of Flat Energy Spectra Upstream of Fast Interplanetary Shocks [PDF]
The Astrophysical Journal, 2023 Interplanetary shocks are large-scale heliospheric structures often caused by eruptive phenomena at the Sun, and represent one of the main sources of energetic particles.

Interplanetary Circumstances of Quasi-Perpendicular Interplanetary Shocks in 1996–2005 [PDF]
Journal of Geophysical Research: Space Physics, 2010 The angle (θBn) between the normal to an interplanetary shock front and the upstream magnetic field direction, though often thought of as a property “of the shock,” is also determined by the configuration of the magnetic field immediately upstream of the shock. We investigate the interplanetary circumstances of 105 near‐Earth quasi‐perpendicular shocks

In situ local shock speed and transit shock speed [PDF]
Annales Geophysicae, 1998 A useful index for estimating the transit speeds was derived by analyzing interplanetary shock observations. This index is the ratio of the in situ local shock speed and the transit speed; it is 0.6–0.9 for most observed shocks.

Shock parameter calculations at weak interplanetary shock waves [PDF]
Annales Geophysicae, 2005 Abstract. A large set of interplanetary shock waves observed using the Ulysses spacecraft is analysed in order to determine their local parameters. For the first time a detailed analysis is extended to the thermodynamic properties of a large number of events. The intention is to relate the shock parameters to the requirements set by MHD shock theory. A

Acceleration of Suprathermal protons near an Interplanetary Shock
Astronomy & Astrophysics, 2023 Context. Interplanetary collisionless shocks are known to be sources of energetic charged particles up to hundreds of MeV. However, the underlying acceleration mechanisms are still under debate.Aims. We determine the properties of suprathermal protons accelerated by the interplanetary shock on 2021 November 3 with the unprecedented ...

Acceleration of an interplanetary shock through the magnetosheath: a global hybrid simulation
Frontiers in Astronomy and Space SciencesAccording 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]
The Astrophysical Journal Supplement Series, 1994 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]
Space Science Reviews, 2007 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.
