Plasmapause surface wave oscillates the magnetosphere and diffuse aurora [PDF]
Nature Communications, 2020 Theoretical studies suggested that plasmapause surface waves related to the sharp inhomogeneity exist and act as a source of geomagnetic pulsations.

On How High-Latitude Chorus Waves Tip the Balance Between Acceleration and Loss of Relativistic Electrons. [PDF]
Geophys Res Lett, 2019 Modeling and observations have shown that energy diffusion by chorus waves is an important source of acceleration of electrons to relativistic energies.

Wave-induced loss of ultra-relativistic electrons in the Van Allen radiation belts. [PDF]
Nat Commun, 2016 The dipole configuration of the Earth's magnetic field allows for the trapping of highly energetic particles, which form the radiation belts. Although significant advances have been made in understanding the acceleration mechanisms in the radiation belts,

Range finding of Alfvén oscillations and direction finding of ion-cyclotron waves by using the ground-based ULF finder [PDF]
Annales Geophysicae, 1997 A new approach to the problem of direction and distance finding of magnetospheric ULF oscillations is described. It is based on additional information about the structure of geoelectromagnetic field at the Earth's surface which is contained in the ...

Geophysical Research Letters, 2021 We present observational support for whistler mode waves guidance by the plasmapause gradients based on a case study and statistical analyses. Due to the combined effects of inhomogeneous magnetic fields and plasma densities, whistler mode waves near the

Prediction of Dynamic Plasmapause Location Using a Neural Network
Space Weather, 2021 As a common boundary layer that distinctly separates the regions of high‐density plasmasphere and low‐density plasmatrough, the plasmapause is essential to comprehend the dynamics and variability of the inner magnetosphere.

The Plasmasphere Boundary Layer [PDF]
Annales Geophysicae, 2004 As an inner magnetospheric phenomenon the plasmapause region is of interest for a number of reasons, one being the occurrence there of geophysically important interactions between the plasmas of the hot plasma sheet and of the cool plasmasphere. There

Improving Predictions of the 3D Dynamic Model of the Plasmasphere
Frontiers in Astronomy and Space Sciences, 2021 In this perspective paper, we review and discuss different ways that can be used to improve the predictions of the models of the plasmaspheric region. The density of the background cold plasma and the plasmapause position are very important to determine ...

Frontiers in Astronomy and Space Sciences, 2021 The plasmapause marks the limit of the plasmasphere and is characterized by a sudden change in plasma density. This can influence the other regions of the magnetosphere, including due to different waves circulating inside and outside the plasmasphere. In

Plasmapause formation at Saturn [PDF]
Journal of Geophysical Research: Space Physics, 2015 AbstractCassini observations during a rapid, high‐latitude, dawnside pass from Saturn's lobe to inner magnetosphere on 25 June 2009 provide strong evidence for the formation of a “plasmapause” at Saturn by Vasyliunas‐type nightside reconnection of previously mass‐loaded flux tubes.
