Cluster Observations of Extreme Energetic Electron Acceleration Event in the Earth's Magnetotail

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Energetic electrons in the Earth's magnetotail play a crucial role in space weather. Although many studies have identified the basic processes of energetic electron acceleration, the conditions that lead to the most extreme acceleration events remain unclear.

Kelvin‐Helmholtz Stability Analysis as a Function of Dipole Tilt and Solar Wind Property

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Kelvin‐Helmholtz instabilities (KHIs) play a critical role in facilitating mass and momentum transport across the magnetopause boundary. Recent studies have demonstrated that KHI occurrence exhibits both seasonal and diurnal variability, with enhanced activity when Earth's magnetic dipole is more closely aligned with the northward direction in

Axial Flux Evolution of Small-scale Magnetic Flux Ropes from 0.06 to 10 au

The Astrophysical Journal Letters
Small-scale magnetic flux ropes (SMFRs) fill much of the solar wind, but their origin and evolution are debated. We apply our recently developed, improved Grad–Shafranov algorithm for the detection and reconstruction of SMFRs to data from Parker Solar ...

Heating of the low-latitude solar wind by dissipation of turbulent magnetic fluctuations

, 2001
We test a theory presented previously to account for the turbulent transport of magnetic fluctuation energy in the solar wind and the related dissipation and heating of the ambient ion population. This theory accounts for the injection of magnetic energy

Formation of H+ PUI Tails Downstream of Distant Interplanetary Shocks

The Astrophysical Journal
New Horizons’ Solar Wind Around Pluto (SWAP) instrument has observed interplanetary shocks from ∼20 to 60 au from the Sun. Different studies have analyzed the effects of these shocks on the solar wind ion (SWI) and interstellar pickup ion (PUI ...

Quantifying finite range plasma turbulence [PDF]

Turbulence is a highly non-linear process ubiquitous in Nature. The nonlinearity is responsible for the coupling of many degrees of freedom leading to an unpredictable dynamical evolution of a turbulent system.

Heating the outer heliosphere by pickup protons

, 2004
There is a growing body of literature that demonstrates the ability of a turbulent cascade within the solar wind to heat the thermal protons. Several sources of energy are required to accomplish the observed heating.

Effects of Waves on the Spectral Anisotropy of the Transition Range in Solar Wind Turbulence

The Astrophysical Journal
In the transition range of the solar wind turbulence, the magnetic spectrum has been observed to be strongly anisotropic with respect to the local mean field. However, the generation mechanism of the anisotropy remains not well understood.

Radar detection of interplanetary shocks : scattering by anisotropic Langmuir turbulence

, 2010
Earth-directed interplanetary shocks associated with coronal mass ejections (CMEs) are known to have a severe impact on the magnetosphere, causing strong geomagnetic storms and substorms. Hence, early detection of such shocks is important.

Evolution of Kelvin-Helmholtz activity on the dusk flank magnetopause [PDF]

, 2008
Our purpose is to characterize the evolution of the magnetopause Kelvin-Helmholtz (KH) wave activity with changes in thickness of the adjacent boundary layer, geomagnetic latitude and interplanetary magnetic field (IMF) orientation.
