Response of convection electric fields in the magnetosphere to IMF orientation change [PDF]
, 2009 [1] The transient response of convection electric fields in the inner magnetosphere to southward turning of the interplanetary magnetic field (IMF) is investigated using in‐situ electric field observations by the CRRES and Akebono spacecraft.

Magnetic signatures of plasma-depleted flux tubes in the Saturnian inner magnetosphere [PDF]
, 2007 Initial Cassini observations have revealed evidence for interchanging magnetic flux tubes in the inner Saturnian magnetosphere. Some of the reported flux tubes differ remarkably by their magnetic signatures, having a depressed or enhanced magnetic ...

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

Erosion of the inner magnetosphere during geomagnetic storms [PDF]
Annales Geophysicae, 1997 Using the empirical magnetic field model dependent on the Dst index and solar wind dynamic pressure, we calculated the behaviour of the contour B = Bs in the equatorial plane of the magnetosphere where Bs is the magnetic field in the subsolar point ...

Injection of a bubble into the inner magnetosphere [PDF]
Geophysical Research Letters, 2008 Magnetic reconnection in the magnetotail or other forms of current sheet disruption are believed to produce plasma bubbles, which consist of flux tubes that have lower entropy content PV5/3 than their surroundings. We present an initial Rice‐Convection‐Model‐based simulation of the injection of a bubble into the inner magnetosphere and explore the ...

Constraining the Origin of Magnetar Flares [PDF]
, 2014 Sudden relaxation of the magnetic field in the core of a magnetar produces mechanical energy primarily in the form of shear waves which propagate to the surface and enter the magnetosphere as relativistic Alfv\'en waves.

Repetitive Emissions of Rising‐Tone Chorus Waves in the Inner Magnetosphere
Geophysical Research Letters, 2020 Chorus waves in the inner magnetospheres of the Earth and other magnetized planets typically occur in the form of discrete and repetitive quasi‐monochromatic emissions with a frequency chirping, which was discovered more than 50 years ago. However, until
