Frequency‐Dependent Responses of Plasmaspheric Hiss to the Impact of an Interplanetary Shock

Geophysical Research Letters, 2021
Plasmaspheric hiss waves are essential for the pitch‐angle scattering and precipitation of energetic electrons and interplanetary shocks may affect these waves.

The Crucial Role of Perpendicular Diffusion in the Longitude Distribution of >10 MeV Solar Energetic Protons

The Astrophysical Journal, 2023
Gradual solar proton events are thought to consist of solar components originating near the Sun and interplanetary components associated with interplanetary shocks, and the role of interplanetary shocks is considered to be crucial in supplying particles ...

Planar Magnetic Structures Downstream of Coronal Mass Ejection–driven Shocks in the Inner Heliosphere

The Astrophysical Journal, 2023
Planar magnetic structures (PMSs), characterized by interplanetary magnetic field vectors remaining parallel to a specific plane, are commonly observed in the solar wind, especially in the sheath region of interplanetary coronal mass ejections (ICMEs ...

Variations of Heavy Ions in Different Types of Interplanetary Shocks

The 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 ...

Turbulence Upstream and Downstream of Interplanetary Shocks

Frontiers 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,

Particle Acceleration at Interplanetary Shocks [PDF]

AIP 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 ...

Characterization of the Transmission and Generation of Turbulence at Interplanetary Shocks

The 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.

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

Journal 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}).

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 ...

Intense Magnetopause Erosion at Earth During the May 2024 Solar Storm

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Earth's main magnetic field forms the magnetosphere, shielding the planet from solar wind plasma. Southward interplanetary magnetic fields erode the magnetosphere, a process known as magnetopause erosion, allowing solar wind penetration close to the Earth.
