The level of non-thermal velocity fluctuations deduced from Doppler spectroscopy and its role on TJ-II confinement

, 2009
The goal of this investigation is to study, in the line of previous works, the level of velocity fluctuations in different scenarios of the TJ-II stellarator.

Differentiating Plumes and Local Torus Segments of Enceladus

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Enceladus's south polar plumes and their surrounding torus segments (local plasma regions formed by plume material diffusion) are key to understanding its magnetospheric interaction; however, clear observational criteria to distinguish them remain lacking.

Real Heights of SuperDARN F Region Echoes Inferred From Electron Density Measurements by the Rankin Inlet and RISR‐C Radars

Radio Science, Volume 61, Issue 2, February 2026.
Abstract This study is one of the first attempts to estimate statistically the real height of SuperDARN F region echoes in the polar cap. To achieve this, measurements of the electron density in the scattering volume of the Rankin Inlet SuperDARN radar are compared with the electron density profiles measured by the incoherent scatter radar RISR‐C ...

Modeling multiphase plasma in the corona: prominences and rain

Living Reviews in Solar Physics
We review major achievements in our understanding of multiphase coronal plasma, where cool-dense and hot-tenuous matter coexists, brought about by advances in modeling and theory, inspired by observations.

BepiColombo at Mercury: Three Flybys, Three Magnetospheres

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract We examine the first three BepiColombo Mercury flybys Using data from the Miniature Ion Precipitation Analyzer (MIPA), an ion mass analyzer in the Search for Exospheric Refilling and Natural Abundances package on the Mercury Planetary Orbiter designed to study magnetospheric dynamics.

Anisotropic Particle Acceleration in Alfvénic Turbulence

The Astrophysical Journal
Alfvénic turbulence is an effective mechanism for particle acceleration in strongly magnetized, relativistic plasma. In this study, we investigate a scenario where turbulent plasma is influenced by a strong guide magnetic field, resulting in highly ...

Statistical Estimate of the Magnetopause Reconnection Rate as a Function of the Interplanetary Magnetic Field Clock Angle

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract The magnetic reconnection rate at the magnetopause is crucial for solar wind and magnetosphere coupling. However, direct measurement is challenging due to inherent uncertainties and limited electron diffusion region statistics, hindering understanding of the guide field's influence on the normalized reconnection rate.

Spatial Distributions of Energetic Electrons and Energetic Ions in the Tail Reconnection Region: Cluster Observations and PIC Simulations

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract High‐energy particles are prevalent in space, and magnetic reconnection is one of the physical processes responsible for their generation. The heating and acceleration of ions and electrons typically occur respectively in the ion diffusion region and the electron diffusion region.

Plasma Magnetosphere Formation Around Oscillating Magnetized Neutron Stars

, 2009
The notion of death line of rotating pulsars is applied to model of oscillating neutron stars. It is shown that the magnetosphere of typical non-rotating oscillating stars may not contain secondary plasma to support the generation of radio emission in ...
