Influence of the Eccentric Geomagnetic Dipole on Longitude Variations of Compressional Upstream Wave Amplitudes in the Topside Ionosphere: Results From the MSS‐1A Satellite

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Based on 2‐year magnetic data from the Macau science satellite, we investigate the compressional Pc3‐4 pulsations (between 16 and 100 mHz) driven by upstream waves (UWs). Our results confirm larger UWs amplitudes in the South Atlantic Anomaly (SAA) longitudes, agreeing with previous missions.

Model study of the earth’s ionosphere electric currents system at high latitudes [PDF]

E3S Web of Conferences
This paper presents a numerical study of the response of high- latitudinal Earth’s ionosphere electric currents system to different magne- tospheric inputs. The ionosphere states were modeled using the Upper At- mosphere Model (UAM).

Orbital modulation of emission of the binary pulsar J0737-3039B

, 2005
In binary radio pulsar system J0737-3039, slow pulsar B shows orbital modulations of intensity, being especially bright at two short orbital phases. We propose that these modulations are due to distortion of pulsar B magnetosphere by pulsar A wind which ...

Observations of the Magnetopause Reconnection Ion Diffusion Region With High‐Density O+ Ions During the May 2024 Superstorm

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Based on high‐resolution measurements from NASA's Magnetospheric Multiscale mission (MMS), we present the first direct observation of an ion diffusion region (IDR) with high number density O+ ions within dayside magnetopause reconnection during the May 2024 superstorm. The O+ ion density reaches a high value of ∼3.3 cm−3.

Magnetospheric and ionospheric vortices response to positive solar wind dynamic pressure pulse

Frontiers in Astronomy and Space Sciences
In this study, we present in-situ observations and global MHD simulations of a clockwise-rotating magnetospheric vortex in the dawnside magnetosphere, accompanied by a conjugate clockwise equivalent ionospheric currents (EICs) vortex following a positive

Current closure in the pulsar magnetosphere [PDF]

Monthly Notices of the Royal Astronomical Society: Letters, 2018
ABSTRACT Current closure in the pulsar magnetosphere holds the key to its structure. We must determine not only the global electric circuit, but also the source of its electric charge carriers. We address this issue with the minimum number of assumptions: (1) The magnetosphere is everywhere ideal and force free, except above the polar ...

Frequency‐Dependent Latitudinal Distributions of Plasmaspheric Plume Hiss Directionality and Amplitude

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Plasmaspheric plume hiss plays a crucial role in shaping Earth's electron radiation belts and influencing magnetosphere–ionosphere energy coupling. However, its generation mechanism remains contested between cyclic‐linear and localized‐nonlinear models. By analyzing over 64,000 high‐resolution plume hiss wave segments from the Van Allen Probes

Magnetopause Boundary Layers in Low Mach CME‐Driven Storm Environment

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Magnetopause boundary layers (BLs) play an important role mediating plasma and energy exchange between the solar wind/magnetosheath and Earth's magnetosphere. Energy exchange across the magnetopause is enhanced during storms, yet little work has been done investigating BLs during storms.

The influence of quiet asymmetric magnetosphere on the cutoff rigidities of the main cone [PDF]

Some earlier studies show that cutoff rigidities of cosmic-ray particles in the model magnetospheric fields of internal and external sources have daily variations caused by asymmetry of the magnetic field due to the currents induced at the magnetopause ...

The current sheet in Jupiter's magnetosphere [PDF]

Journal of Geophysical Research, 1976
A theoretical model is presented for the plasma in the Jovian magnetosphere whose pressure is comparable to the corotational energy density. The model predicts a thin current sheet of 1 Jupiter radius to 2 Jupiter radii half-thickness. The current sheet lies almost precisely in the magnetic equatorial plane and is not appreciably warped as suggested ...
