Models of field-aligned currents needful to simulate the substorm variations of the electric field and other parameters observed by EISCAT [PDF]
Annales Geophysicae, 1996 We have used the global numerical model of the coupled ionosphere-thermosphere-protonosphere system to simulate the electric-field, ion- and electron-temperature and -concentration variations observed by EISCAT during the substorm event of 25 March ...

On the role of neutral flow in field-aligned currents [PDF]
Annales Geophysicae, 2018 In this brief note we explore the role of the neutral atmosphere in magnetosphere–ionosphere coupling. We analyze momentum balance in the ion rest frame to form hypotheses regarding the role of neutral momentum in the lower ionosphere during ...

Modeling of ion dynamics in the inner geospace during enhanced magnetospheric activity [PDF]
Annales Geophysicae, 2016 We investigate the effect of magnetic disturbances on the ring current buildup and the dynamics of the current systems in the inner geospace by means of numerical simulations of ion orbits during enhanced magnetospheric activity.

Current Flows in Pulsar Magnetospheres
Chinese Journal of Astronomy and Astrophysics, 2006 The global structure of the current flows in pulsar magnetospheres is investigated, with rough calculations of the elements in the magnetospheric circuit. It is emphasized that the potential of critical field lines is the same as that of interstellar medium, and that the pulsars whose rotation axes and magnetic dipole axes are parallel should be ...

Azimuthal magnetic fields in saturn's magnetosphere: Effects associated with plasma sub-corotation and the magnetopause-tail current system [PDF]
, 2003 We calculate the azimuthal magnetic fields expected to be present in Saturn’s magnetosphere associated with two physical effects, and compare them with the fields observed during the flybys of the two Voyager spacecraft.

3-D force-balanced magnetospheric configurations [PDF]
Annales Geophysicae, 2004 The knowledge of plasma pressure is essential for many physics applications in the magnetosphere, such as computing magnetospheric currents and deriving mag-netosphere-ionosphere coupling.
