The θBn problem: Determination of local magnetic parameters of interplanetary shocks from in situ IMF data [PDF]

open access: yesGeofísica Internacional, 2001
The angle θBn is the angle between the upstream magnetic field and the shock normal direction and is important for many phenomena in interplanetary physics.

IMF By‐Controlled Dawn–Dusk and Hemispheric Asymmetries of Kelvin–Helmholtz Waves and Reconnection Geometry Under Negative Dipole Tilt

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Along with magnetic reconnection, Kelvin‐Helmholtz (KH) waves are the main mechanisms controlling the solar wind‐magnetosphere interaction, enabling plasma transport into the magnetosphere due to secondary reconnection, diffusion and wave‐particle interactions.

Dynamic acceleration of energetic protons by an interplanetary collisionless shock

open access: yes
Context. Interplanetary collisionless shocks are known to be capable of accelerating charged particles up to hundreds of MeV. However, the underlying acceleration mechanisms are still under debate. Aims.

A Novel Blast Wave Solution for the Propagation of Coronal And Interplanetary Shocks

open access: yesThe Astrophysical Journal
Coronal mass ejections (CMEs) and their associated shock waves have severe space weather effects in the near-Earth space. Therefore, predicting the propagation and arrival time of the CME/shock is an important component of the space weather forecast.

Automatic Identification of Interplanetary Shocks Based on Machine Learning

open access: yesSpace Weather
Fast forward interplanetary shocks (FFs) are one of the primary drivers of space weather events. This study presents an automated detection algorithm for FFs based on a multilayer perceptron model, utilizing in situ measurements of interplanetary ...

Variations of Heavy Ions in Different Types of Interplanetary Shocks

open access: yesThe Astrophysical Journal
Heavy ions upstream and downstream of interplanetary shocks are not only subject to acceleration, heating, and spatiotemporal modulation during their propagation in interplanetary space, but they can also, in turn, influence the dynamical properties of ...

Corotating drift-bounce resonance of plasmaspheric electron with poloidal ULF waves

open access: yesEarth and Planetary Physics, 2017
The purpose of this paper is to understand how low energy plasmaspheric electrons respond to ULF waves excited by interplanetary shocks impinging on magnetosphere. It is found that both energy and pitch angle dispersed plasmaspheric electrons with energy

Spectral Evolution of Pickup Ions across Interplanetary Shocks in the Outer Heliosphere: Observational Constraints and Transport Simulations

open access: yesThe Astrophysical Journal Letters
Pickup ions (PUIs) often experience acceleration and heating as they traverse interplanetary shocks, leading to the formation of a distinct suprathermal tail in their energy spectra downstream of the shock.

Change in interplanetary shock acceleration preceding STIP Interval 17 [PDF]

open access: yes, 1987
The intensity and frequency of shock acceleration events in the interplanetary medium decreased dramatically in early 1985. Low energy ions were observed by IMP 8 at 1 AU and Voyagers 1 and 2 at 22 and 16 AU, respectively.
