Exploring Jupiter's Mid‐Latitude Dusk Magnetopause: The Impact of Magnetic Reconnection

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The Juno mission has elucidated magnetosphere processes, structure, and dynamics via multi‐instrument plasma and magnetic field observations. In this study, these instruments are used to identify magnetic reconnection during the Juno extended mission from a survey of 490 magnetopause crossings at the mid‐latitude southern dusk magnetopause ...

The Athena space X‐ray observatory and the astrophysics of hot plasma

, 2020
International audienceThe properties (temperature, density, chemical composition, velocity) of hot astrophysical plasma and the physical processes affecting them (heating/cooling, turbulence, shocks, acceleration) can be probed by high resolution X-ray ...

Radio Sounding Determination of Two‐Dimensional Plasma Structure Velocity

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The Mars spacecraft Tianwen‐1 transmitted radio signals to Earth for its orbit determination. The frequencies of the radio signals exhibited sharp variations when an ICME passed through the Mars‐Earth signal path on 18 June 2021. These sharp variations were observed at different ground stations at different times. This was most probably caused

A Study of Kelvin‐Helmholtz Instability at Unmagnetized Planets by Finite Larmor Radius MHD

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Kelvin–Helmholtz instability (KHI) at unmagnetized planetary ionopauses plays a key role in driving solar wind–ionosphere coupling and planetary ion escape. We investigate KHI using a two‐dimensional finite Larmor radius (FLR) MHD model.

Cross‐Scale Energy Transfer at Dipolarization Front in the Earth's Magnetotail

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Dipolarization front (DF) is a key structure for energy conversion and transport in planetary magnetotails. Although multiscale processes have been observed around DFs, quantitative analyses of cross‐scale coupling remain lacking. Here, we calculate cross‐scale transfer rate for different energy channels at a DF using Magnetospheric Multiscale

The Hydrodynamic Thermal Continuum, with Applications to Stratified Atmospheres and 1D Coronal Loop Models

The Astrophysical Journal
Using both analytical and numerical means, we demonstrate that linear stability analysis of a hydrodynamic stratified atmosphere or a 1D coronal loop model in nonadiabatic settings features a thermal continuum corresponding to highly localized ...

Quasi‐Homologous Solar Flares and Impacts on Thermospheric Density and Satellite Orbital Drag

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Quasi‐Homologous Flaring (QHF) activity from active regions on the Sun releases intense electromagnetic radiation in recurrent bursts over extended periods. In this letter, we present the effects of recurrent impulsive extreme ultraviolet (EUV) heating on thermospheric neutral density and the resulting atmospheric drag on satellites based on ...
