Alfvén waves in the magnetosphere generated by shock wave/plasmapause interaction
Solar-Terrestrial Physics, 2019 We study Alfvén waves generated in the magnetosphere during the passage of an interplanetary shock wave. After shock wave passage, the oscillations with typical Alfvén wave dispersion have been detected in spacecraft observations inside the magnetosphere.

Frontiers in Astronomy and Space Sciences, 2023 Empirical models have been previously developed using the large dataset of satellite observations to obtain the global distributions of total electron density and whistler-mode wave power, which are important in modeling radiation belt dynamics.

The relationship between plasmapause, solar wind and geomagnetic activity between 2007 and 2011 [PDF]
Annales Geophysicae, 2015 Taking advantage of the Cluster satellite mission and especially the observations made by the instrument WHISPER to deduce the electron number density along the orbit of the satellites, we studied the relationships between the plasmapause positions ...

Comparisons between EUV/IMAGE observations and numerical simulations of the plasmapause formation [PDF]
Annales Geophysicae, 2005 Simulations of plasmapause formation described in Pierrard and Lemaire (2004) predict the shape and equatorial distance of the plasmapause as a function of the geomagnetic activity index Kp.

New plasmapause model derived from CHAMP field-aligned current signatures [PDF]
Annales Geophysicae, 2013 We introduce a new model for the plasmapause location in the equatorial plane. The determination of the L-shell bounding the plasmasphere is based on magnetic field observations made by the CHAMP satellite in the topside ionosphere.

Plasmapause, Convection, and Reconnection [PDF]
Journal of Geophysical Research: Space Physics, 2019 Abstract Being one of the first generation of space scientists who entered this field right after the space became accessible to in situ observations, I had good luck of addressing some of the basic questions in this field from the early years of my carrier.

An auroral westward flow channel (AWFC) and its relationship to field-aligned current, ring current, and plasmapause location determined using multiple spacecraft observations [PDF]
Annales Geophysicae, 2007 An auroral westward flow channel (AWFC) is a latitudinally narrow channel of unstable F-region plasma with intense westward drift in the dusk-to-midnight sector ionosphere. AWFCs tend to overlap the equatorward edge of the auroral oval, and their life

A machine-learning-based electron density (MLED) model in the inner magnetosphere
Earth and Planetary Physics, 2022 Plasma density is an important factor in determining wave-particle interactions in the magnetosphere. We develop a machine-learning-based electron density (MLED) model in the inner magnetosphere using electron density data from Van Allen Probes between ...

Geophysical Research Letters, 2022 In the magnetosphere of the Earth, lower hybrid drift (LHD) waves effectively cause plasma diffusion and couple well to both electrons and ions. LHD waves have the characteristics of linear polarization and highly oblique propagation with frequencies ...

Polar observations of electron density distribution in the Earth’s magnetosphere. 2. Density profiles [PDF]
Annales Geophysicae, 2002 Using spacecraft potential measurements of the Polar electric field experiment, we investigate electron density variations of key plasma regions within the magnetosphere, including the polar cap, cusp, trough, plasmapause, and auroral zone.
