Asymmetric magnetic reconnection with a flow shear and applications to the magnetopause [PDF]

open access: yes, 2015
We perform a theoretical and numerical study of anti-parallel 2D magnetic reconnection with asymmetries in the density and reconnecting magnetic field strength in addition to a bulk flow shear across the reconnection site in the plane of the reconnecting

First current density measurements in the ring current region using simultaneous multi-spacecraft CLUSTER-FGM data [PDF]

open access: yesAnnales Geophysicae, 2005
The inner magnetosphere's current mapping is one of the key elements for current loop closure inside the entire magnetosphere. A method for directly computing the current is the multi-spacecraft curlometer technique, which is based on the application ...

Scientists confer on magnetospheric current systems from a global viewpoint [PDF]

open access: yesEos, Transactions American Geophysical Union, 1999
A ubiquitous feature of all magnetospheres is the presence of magnetic field and plasma. Their spatial and temporal variations can be addressed in terms of the electromagnetic coupling between one region of the magnetosphere and another.Outstanding issues of electromagnetic processes in the magnetosphere from the global viewpoint were revisited early ...

Three-dimensional Analytical Description of Magnetised Winds from Oblique Pulsars

open access: yes, 2015
Rotating neutron stars, or pulsars, are plausibly the source of power behind many astrophysical systems, such as gamma-ray bursts, supernovae, pulsar wind nebulae and supernova remnants.

IMPALAS: Investigation of MagnetoPause Activity using Longitudinally-Aligned Satellites—a mission concept proposed for the ESA M3 2020/2022 launch [PDF]

open access: yes, 2012
The dayside magnetopause is the primary site of energy transfer from the solar wind into the magnetosphere, and modulates the activity observed within the magnetosphere itself.

The six-month line in geomagnetic long series [PDF]

open access: yesAnnales Geophysicae, 2004
Daily means of the horizontal components X (north) and Y (east) of the geomagnetic field are available in the form of long series (several tens of years). Nine observatories are used in the present study, whose series are among the longest.

Magnetospheric signatures of ionospheric density cavities observed by cluster [PDF]

open access: yes, 2015
AJBR ackowledges support from STFC under consolidated grant ST/K000993/1.We present Cluster measurements of large amplitude electric fields corre- lated with intense downward field-aligned currents, observed during a nightside crossing of the auroral ...

Ps 6 disturbances: relation to substorms and the auroral oval [PDF]

open access: yesAnnales Geophysicae, 2003
Ps 6 disturbances and associated omega bands are often considered to be part of the phenomenology of the recovery phase of substorms. We note cases of the initiation of Ps 6 activity at or very near the time of onset, either of a substorm expansive

A study of omega bands and Ps6 pulsations on the ground, at low altitude and at geostationary orbit [PDF]

open access: yes, 1999
We investigate the electrodynamic coupling between auroral omega bands and the inner magnetosphere. The goal of this study is to determine the features to which omega bands map in the magnetosphere.

Observations of convection in the dayside magnetosphere by the beam instrument on Geotail [PDF]

open access: yesAnnales Geophysicae, 2001
We report observations of magnetospheric convection by the beam instrument, EFD-B, on Geotail. The region analyzed in this study is mainly the afternoon sector of the magnetosphere between L = 9.7 - 11.5.
