Plasmapause surface wave oscillates the magnetosphere and diffuse aurora [PDF]

open access: yesNature Communications, 2020
Theoretical studies suggested that plasmapause surface waves related to the sharp inhomogeneity exist and act as a source of geomagnetic pulsations.

Prediction of Dynamic Plasmapause Location Using a Neural Network

open access: yesSpace 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.

Empirical plasmapause models from magnetic indices [PDF]

open access: yesGeophysical Research Letters, 2003
We use a database of CRRES in situ observations of plasmapause crossings to build empirical models of the plasmapause location as a function of geomagnetic indices. Previous models used the maximum value in Kp during the hours to days leading up to the plasmapause crossing.

Observational Evidence for Whistler Mode Waves Guided/Ducted by the Inner and Outer Edges of the Plasmapause

open access: yesGeophysical 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

The Plasmasphere Boundary Layer [PDF]

open access: yesAnnales 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

open access: yesFrontiers 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 ...

Links of the Plasmapause With Other Boundary Layers of the Magnetosphere: Ionospheric Convection, Radiation Belt Boundaries, Auroral Oval

open access: yesFrontiers 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]

open access: yesJournal 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.

Van Allen Probes Observations of Oxygen Ions at the Geospace Plume

open access: yesFrontiers in Astronomy and Space Sciences, 2021
The geospace plume couples the ionosphere, plasmasphere, and magnetosphere from sub-auroral regions to the magnetopause, on polar field lines, and into the magnetotail.

Ionospheric and magnetospheric “plasmapauses” [PDF]

open access: yesPlanetary and Space Science, 1978
Abstract During August 1972, Explorer 45 orbiting near the equatorial plane with an apogee of ∼5.2 R e traversed magnetic field lines in close proximity to those simultaneously traversed by the topside ionospheric satellite ISIS 2 near dusk in the L range 2.0–5.4.
