Interplanetary Magnetic Field Curvature and Its Role in Particle Acceleration: Magnetospheric Multiscale and Solar Orbiter Observations

The Astrophysical Journal
The curvature of the magnetic field plays a crucial role in magnetic confinement, magnetic reconnection, particle heating, and acceleration. Though the magnetic field curvature has been sufficiently investigated in the terrestrial magnetosheath, there is

Magnetic field of the transition current system: dawn-dusk asymmetry [PDF]

Annales Geophysicae, 2007
In this paper we consider the interactions of coronal mass ejections (CMEs) with the Earth's magnetosphere for the specific case in which there is a sharp increase in the dynamic pressure (interplanetary shock) that is associated with a simultaneous ...

Statistical Analysis of the Warm Plasma Cloak in the Dayside Magnetosphere: 9 Years of MMS Observations

Geophysical Research Letters, Volume 52, Issue 13, 16 July 2025.
Abstract The warm plasma cloak (WPC) is a plasma population located in the outer magnetosphere. It is composed primarily of electrons and H+ ${\mathrm{H}}^{+}$ ions with energies of tens to hundreds electronvolts and can contain significant amounts of O+ ${\mathrm{O}}^{+}$. We conduct a statistical survey of the WPC using 9 years of observations in the

The Ionopause at Mars and Its Correlation With Magnetic Topology and Plasma Pressure

Journal of Geophysical Research: Space Physics, Volume 130, Issue 7, July 2025.
Abstract We utilize Mars Atmosphere and Volatile Evolution (MAVEN) observations to investigate the ionopause boundary at Mars, the formation process of which is not yet well described. We focus on the eighth deep dip campaign (DD8), which consists of 50 consecutive orbits, and we develop an automated routine to identify ionopause boundaries in electron

Occurrence of Equatorial Plasma Bubbles during Intense Magnetic Storms

International Journal of Geophysics, 2011
An important issue in low-latitude ionospheric space weather is how magnetic storms affect the generation of equatorial plasma bubbles. In this study, we present the measurements of the ion density and velocity in the evening equatorial ionosphere by the

Comparisons Between the Global Ionosphere Thermosphere Model and HIWIND Measurements

Journal of Geophysical Research: Space Physics, Volume 130, Issue 7, July 2025.
Abstract Neutral winds in the daytime middle thermosphere are difficult to measure. The High altitude Interferometer WIND Observation instrument made measurements of these winds from a balloon in the summers of 2011 and 2018 during both daytime and nighttime at high latitudes.

Evidence of Confinement of Solar-energetic Particles to Interplanetary Magnetic Field Lines [PDF]

, 2011
We present new observations of solar-energetic particles (SEPs) associated with impulsive solar flares that show evidence for their confinement to interplanetary magnetic field lines.

Robust Global Analysis of Mid‐Latitude Ionospheric Trough Morphology

Journal of Geophysical Research: Space Physics, Volume 130, Issue 7, July 2025.
Abstract This study characterizes the main ionospheric trough (MIT) using a newly implemented detection method applied to ground‐based Global Navigation Satellite System data. The MIT is a region of plasma depletion occurring primarily in the nighttime sub‐auroral F‐region ionosphere. Analysis is based on ground‐based ionosphere total electron content (
