Reflected ions at interplanetary shocks [PDF]

open access: yesGeophysical Research Letters, 2010
This paper shows that the shock dissipation mechanism changes profoundly from the inner to outer heliosphere and that pickup ions are responsible for shock dissipation beyond 35 AU. We make the first study of reflected ions in ICME sheaths downstream of interplanetary shocks observed by Voyager 2 from 1–80 AU.

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 ...

Physical Characteristics of Coronal Region Driving Out the Interplanetary Shock [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2008
Using the solar wind data of 2000 observed by ACE, We classified the interplanetary shock on basis of shock driver. We examined the physical properties of shock drivers such as the ratio of charge states(O7/O6) and thermal index(I_{th}).

Particle Acceleration at Interplanetary Shocks [PDF]

open access: yesAIP Conference Proceedings, 2008
The acceleration of interstellar pick-up ions as well as solar wind species has been observed at a multitude of interplanetary (IP) shocks by different spacecraft. This paper expands upon previous work modeling the phase space distributions of accelerated ions associated with the shock event encountered on day 292 of 1991 by the Ulysses mission at 4.5 ...

Acceleration of Suprathermal protons near an Interplanetary Shock

open access: yesAstronomy & 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 ...

Fast damping of ultralow frequency waves excited by interplanetary shocks in the magnetosphere

open access: yes, 2015
Analysis of Cluster spacecraft data shows that intense ultralow frequency (ULF) waves in the inner magnetosphere can be excited by the impact of interplanetary shocks and solar wind dynamic pressure variations. The observations reveal that such waves can

Characterization of the Transmission and Generation of Turbulence at Interplanetary Shocks

open access: yesThe Astrophysical Journal
We study the transmission and characteristics of turbulent magnetohydrodynamic (MHD) fluctuations from upstream to downstream regions of interplanetary (IP) shocks using the linear mode decomposition (LMD) technique of G. P. Zank et al.

Plasmaspheric High‐Frequency Whistlers as a Candidate Cause of Shock Aurora at Earth

open access: yesGeophysical Research Letters, 2023
Auroral brightening driven by interplanetary shocks on Earth's closed magnetic field lines is commonly attributed to the 0.1–10 keV electron precipitations by electron cyclotron harmonic waves and whistler‐mode chorus waves in the low‐density region.

Turbulence Upstream and Downstream of Interplanetary Shocks

open access: yesFrontiers in Physics, 2021
The paper reviews the interaction of collisionless interplanetary (IP) shocks with the turbulent solar wind. The coexistence of shocks and turbulence plays an important role in understanding the acceleration of particles via Fermi acceleration mechanisms,

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

open access: yesJournal of Field Robotics, Volume 43, Issue 7, Page 4475-4514, October 2026.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full
