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.

Multi‐Species Energy‐Banded Ions in the Ionosphere During the 21 January 2005 Magnetic Storm: Low‐Altitude Edge of the Warm Plasma Cloak

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract During the 21–22 January 2005 magnetic storm, the FAST satellite observed warm (< few keV) ions in discrete energy bands on the dayside at ∼3,000 km altitude for more than 6.5 hr. We suggest that the ionospheric energy‐banded ions represent the low‐altitude edge of the warm plasma cloak observed simultaneously by magnetospheric satellites ...

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 ...

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.

Debye‐Scale Bipolar Structures and Their Role in the Electron Trajectory Instability at the Bow Shock

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract A number of mechanisms have been suggested to operate within the terrestrial bow shock to redistribute energy contained in the incoming solar wind flow. The majority of mechanisms involve the generation of turbulence while some are based on particle motion alone.

Derivation of Ambient Electron Density Using Spacecraft Potential Measurements From the MMS and Van Allen Satellites: Application to the Plasmasphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract We investigate the empirical relationship between the spacecraft potential (Vs) measured by the Electric Field Double Probes, and the electron density (Ne) measured by the Fast Plasma Instrument on the MMS spacecraft. We derive their relationship during fast‐mode intervals when the Active Spacecraft Potential Control Devices are off.

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

Mshpy23: a user-friendly, parameterized model of magnetosheath conditions

Earth and Planetary Physics
Lunar Environment heliospheric X-ray Imager (LEXI) and Solar wind−Magnetosphere−Ionosphere Link Explorer (SMILE) will observe magnetosheath and its boundary motion in soft X-rays for understanding magnetopause reconnection modes under various solar wind ...

Impact of Induced Electric Fields Inside the Magnetopause on Magnetopause Shadowing of Radiation Belt Electrons

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Loss of relativistic electrons with energies above 0.5 MeV through the magnetopause, commonly referred to as magnetopause shadowing, has been extensively investigated using both simulations and observations. However, direct and systematic observational evidence remains limited. In this study, we extend a previously developed magnetopause model
