Magnetospheric convection electric field dynamics andstormtime particle energization: case study of the magneticstorm of 4 May 1998 [PDF]
Annales Geophysicae, 2004 It is shown that narrow channels of high electric field are an effective mechanism for injecting plasma into the inner magnetosphere. Analytical expressions for the electric field cannot produce these channels of intense plasma flow, and thus, result ...

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.

Solar wind dependence of ion parameters in the earth's magnetospheric region calculated from CLUSTER observations [PDF]
, 2008 Moments calculated from the ion distributions (~0–40 keV) measured by the Cluster Ion Spectrometry (CIS) instrument are combined with data from the Cluster Flux Gate Magnetometer (FGM) instrument and used to characterise the bulk properties of the plasma

The inner magnetosphere imager mission [PDF]
, 1994 The Inner Magnetosphere Imager (IMI) mission will carry instruments to globally image energetic neutral atoms, far and extreme ultraviolet light, and X-rays. These imagers will see the ring current, inner plasmasheet, plasmasphere, aurora, and geocorona. With these observations it will be possible, for the first time, to develop an understanding of the

Asymmetric distribution of reconnection jet fronts in the Jovian nightside magnetosphere [PDF]
, 2013 Magnetic reconnection plays important roles in mass transport and energy conversion in planetary magnetospheres. It is considered that transient reconnection causes localized auroral arcs or spots in the Jovian magnetosphere, by analogy to the case in ...

IMF BY and the seasonal dependences of the electric field in the inner magnetosphere [PDF]
Annales Geophysicae, 2005 It is known that the electric field pattern at high latitudes depends on the polarity of the Y component of the interplanetary magnetic field (IMF BY) and season. In this study, we investigate the seasonal and BY dependences in the inner magnetosphere

Progress in understanding the inner magnetosphere [PDF]
Eos, Transactions American Geophysical Union, 2012 Inner Magnetosphere Coupling 2; Los Angeles, California, 19–22 March 2012 Solar activity can energize Earth's magnetosphere. Coupled plasma interactions—involving multiscale electromagnetic fields, currents, and waves—either dissipate this energy into the ionosphere (to influence upper atmospheric chemistry and possibly climate) or store it in belts of

Magnetosphere-ionosphere coupling currents in Jupiter's middle magnetosphere
, 2004 This thesis is a theoretical study of the magnetosphere-ionosphere coupling current system in Jupiter's middle magnetosphere associated with the breakdown of corotation of iogenic plasma and the jovian main auroral oval. The study initially investigates

Magnetopause displacements: the possible role of dust [PDF]
Annales Geophysicae, 2011 Large compressions of the magnetopause are proposed to occasionally result from temporary encounters of the magnetosphere with dust streams in interplanetary space. Such streams may have their origin in cometary dust tails or asteroids which cross the

Filamentary Currents and Alfvénic Vortices in the Inner Magnetosphere
Geophysical Research Letters, 2020 We show that broadband low‐frequency Alfvénic field variations observed in the inner‐magnetosphere from the Van Allen Probes during geomagnetically disturbed intervals are composed of multiscale current sheets, current filaments, flow shears, and ...
