Probing magnetars magnetosphere through X-ray polarization measurements

open access: yes, 2013
The study of magnetars is of particular relevance since these objects are the only laboratories where the physics in ultra-strong magnetic fields can be directly tested.

The magnetospheric radius of an inclined rotator in the magnetically threaded disk model [PDF]

open access: yes, 2018
The estimate of the magnetospheric radius in a disk-fed neutron star X-ray binary is a long standing problem in high energy Astrophysics. We review the magnetospheric radius calculations in the so-called magnetically threaded disk model, comparing the ...

Magnetospheric Configuration with Magnetotail Current

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2000
Magnetospheric configuration with magneto tail current is studied on a two-dimensional formulation. The planar magnetic field is represented by an analytic function of a complex variable that represents points of the. Noon-midnight plane. In our treatment, which accounts for both-the Chapman-Ferraro magnetopause current and the magnetotail current, the

A Novel Technique for Extracting the Tidal Magnetic Field: Methodology and Application to a Pre‐Processed Dataset of CSES and Swarm

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The oceanic tidal magnetic field, mainly driven by the circular orbital motion of the Moon, is an essential part of the time‐varying geomagnetic field. The previously adopted time‐harmonic (TH) base worked well in fitting the primary M2 ${M}_{2}$ tidal field, but extracting the other weaker modes like the N2 ${N}_{2}$ was difficult with only a

Observations of High‐Resolution Two‐Dimensional Ionospheric Flow Dynamics Associated With Poleward Boundary Intensifications

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Poleward boundary intensifications (PBIs) are one of the most common auroral disturbances and have been shown to play a key role in substorm dynamics. PBIs are commonly interpreted as the ionospheric signature of magnetotail reconnection, providing insight into X‐line evolution.

Waiting for the Big One: A New Class of SGR Outbursts?

open access: yes, 2002
It is suggested that magnetars eventually become unstable to a dynamic overturning instability that destroys most of their dipole moment in a single event. It is further suggested that such an instability would produce a supergiant version of the largest

Evolution of Magnetospheric Boundary Layers Under the 10 May 2024 ICME Impact

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract On 10 May 2024, an interplanetary coronal mass ejection‐driven shock impacted the dayside magnetopause, compressing it to ∼5 RE. A northward interplanetary magnetic field suppressed dayside reconnection and allowed a clear investigation of the magnetosphere response.

Three Dimensional Computer Modeling of Magnetospheric Substorm [PDF]

open access: yesJournal of Astronomy and Space Sciences, 1989
Magnetospheric substorm in the magnetotail region is studied numericallu by means of a three dimensional MHD code. The analytic solution for the quiet magnetotail is employed as an initial configuration.

Magnetotail energy dissipation during an auroral substorm. [PDF]

open access: yes, 2016
Violent releases of space plasma energy from the Earth's magnetotail during substorms produce strong electric currents and bright aurora. But what modulates these currents and aurora and controls dissipation of the energy released in the ionosphere ...
