Ion velocity distributions within the LLBL and their possible implication to multiple reconnections [PDF]

Annales Geophysicae, 2004
We analyze two LLBL crossings made by the Interball-Tail satellite under a southward or variable magnetosheath magnetic field: one crossing on the flank of the magnetosphere, and another one closer to the subsolar point.

A Physics‐Informed Neural Network Approach to the Gannon Storm

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Extreme geomagnetic storms, such as the May 2024 Gannon event, pose significant risks to technological infrastructure, requiring robust forecasting models. Here, we apply Physics‐Informed Neural Networks (PINNs) to the Burton equation to model the storm's ring current dynamics by studying the temporal evolution of the SuperMAG SMR index during

Mirror waves and mode transition observed in the magnetosheath by Double Star TC-1 [PDF]

Annales Geophysicae, 2009
The Double Star TC-1 magnetosheath pass on 26 February 2004 is used to investigate magnetic field fluctuations. Strong compressional signatures which last for more than an hour have been found near the magnetopause behind a quasi-perpendicular bow ...

First simultaneous observations of flux transfer events at the high-latitude magnetopause by the cluster spacecraft and pulsed radar signatures in the conjugate ionosphere by the CUTLASS and EISCAT radars [PDF]

, 2001
Cluster magnetic field data are studied during an outbound pass through the post-noon high-latitude magnetopause region on 14 February 2001. The onset of several minute perturbations in the magnetospheric field was observed in conjunction with a ...

Asymmetrically Distributed Kelvin‐Helmholtz Instability at Venusian Magnetosphere

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The asymmetric distribution of Kelvin‐Helmholtz (KH) instability at Venusian ionopause is investigated using a multifluid model. Results show that KH instability distributes asymmetrically, preferentially developing in the −E (anti‐parallel to the interplanetary electric field) hemisphere.

Two types of mirror mode waves in the Kronian magnetosheath

Earth and Planetary Physics, 2023
A mirror mode wave is a fundamental magnetic structure in the planetary space environment that is persistently compressed by solar wind, especially in the magnetosheath.

Cold ions of ionospheric origin observed at the dayside magnetopause and their effects on magnetic reconnection [PDF]

, 2015
Thesis (Ph.D.) University of Alaska Fairbanks, 2015Magnetic reconnection at the dayside magnetopause is one of the most important mechanisms that efficiently transfers solar wind particles, momentum, and energy into the magnetosphere.

Plasma Dynamics and Structure of Titan's Induced Magnetosphere From Wave, Magnetic Field, and Plasma Measurements

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract In this study, we combine Cassini fields and particle observations to investigate Titan's induced magnetosphere from the TA to T82 flybys, including flybys from the Cassini prime, equinox, and part of the solstice mission, to investigate the average location and the shape of Titan's induced magnetosphere. Although earlier studies have provided

Magnetosheath plasma expansion: Hybrid simulations [PDF]

Geophysical Research Letters, 2007
We investigate the effect of slow expansion on a magnetosheath plasma and low‐frequency waves using a two‐dimensional hybrid expanding box simulation. We start our simulation with a homogeneous high beta plasma, which is marginally stable to the mirror and proton cyclotron instabilities.

MMS Observations of Electron Vorticity in the Earth’s Magnetosheath

The Astrophysical Journal
The Earth’s magnetosheath serves as a natural laboratory to study the transition of highly turbulent fluctuations. The fundamental information about plasma turbulences can be examined observationally with the help of electron vorticity measurements. This
