Witnessing the magnetospheric boundary at work in Vela X-1

, 2011
We present an analysis of the Vela X-1's "off-states" based on Suzaku observations taken in June 2008. Defined as states in which the flux sudden decreases below the instrumental sensitivity, these "off-states" have been interpreted by several authors as

Longitudinal Variability of Pre‐Midnight Equatorial Plasma Bubbles Under Disturbed Geomagnetic Conditions

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Equatorial plasma bubbles (EPBs) pose significant challenges to trans‐ionospheric radio communication and navigation systems. Because of their disruptive effects, evaluating and predicting them is key for the development of space systems. The influence of geomagnetic activity on EPBs remains unclear, partly due to limited low‐latitude neutral ...

The Origin of Non‐Gyrotropic Distribution Functions in Compressed Current Sheets

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Non‐gyrotropic distribution functions are often observed in thin current sheets prior to magnetic reconnection. This study uses NASA's Magnetospheric Multiscale mission data to confirm a novel source of agyrotropy in compressed current sheets and highlights its significance in reconnection.

Axisymmetric force-free magnetosphere of a pulsar. I. The structure close to the magnetic axis

, 2012
The stationary axisymmetric force-free magnetosphere of a pulsar is studied analytically. The pulsar equation is solved in the region close to the magnetic axis. Proceeding from linearization of the current function in the axial region, we find the axial

Mini-magnetospheres and Moon-magnetosphere interactions: Overview Moon-magnetosphere Interactions

, 2019
"Moon-magnetosphere interaction" stands for the interaction of magnetospheric plasma with an orbiting moon. Observations and modeling of moon-magnetosphere interaction is a highly interesting area of space physics because it helps to better understand the basic physics of plasma flows in the universe and it provides geophysical information about the ...

Magnetosphere

Eos, Transactions American Geophysical Union, 1971
This report on progress in the magnetosphere covers the calendar years 1967–1970 inclusive. Bibliographical coverage is also for the period 1967–1970: therefore, results presented at conferences but not yet available in published form may be cited.The topic of the magnetosphere has been divided into five sections: magnetopause; magnetosphere structure,

Role of Large‐Scale Traveling Ionospheric Disturbances in the Positive Storm Phase Observed by the Millstone Hill Radar and GNSS TEC Measurements

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract A moderate geomagnetic storm was driven by high‐speed solar wind stream on 14 March 2016. We show that large‐scale traveling ionospheric disturbances (LSTIDs) played a significant role in producing the ionospheric storm positive phase at mid‐latitudes in the North American sector.

Outer Radiation Belt Dynamics During the October 2012 Storm Revisited: Rapid Inward Radial Transport From a Dynamic Outer Boundary

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Earth's outer radiation belt electron flux is highly variable and can be enhanced by over an order of magnitude over timescales less than one day, as observed during the October 2012 storm. Previous studies of this storm (e.g., Reeves et al., 2013, https://doi.org/10.1126/science.1237743) have invoked local acceleration to explain this ...
