Dependence of the open-closed field line boundary in Saturn's ionosphere on both the IMF and solar wind dynamic pressure:comparison with the UV auroral oval observed by the HST [PDF]

, 2008
We model the open magnetic field region in Saturn's southern polar ionosphere during two compression regions observed by the Cassini spacecraft upstream of Saturn in January 2004, and compare these with the auroral ovals observed simultaneously in ...

Large‐Scale Magnetosheath Jets Formed by Shock‐Discontinuity Interactions: A Three‐Dimensional Global Hybrid Simulation

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Magnetosheath high‐speed jets with enhanced dynamic pressure are common in Earth's magnetosheath and can impinge on the magnetopause, driving pronounced boundary deformation. Recent observations indicate that shock–discontinuity interactions (SDIs) can generate magnetosheath jets, but the formation mechanism is still unclear.

Modeling magnetospheric fields in the Jupiter system

, 2017
The various processes which generate magnetic fields within the Jupiter system are exemplary for a large class of similar processes occurring at other planets in the solar system, but also around extrasolar planets.

The magnetosphere-ionosphere observatory (MIO) mission concept

Frontiers in Astronomy and Space Sciences, 2022
MIO (Magnetosphere-Ionosphere Observatory) is designed to definitively fix a cause-and-effect problem: In the nightside magnetosphere-ionosphere system we don’t know what is connected to what.

The initial temporal evolution of a feedback dynamo for Mercury

, 2010
Various possibilities are currently under discussion to explain the observed weakness of the intrinsic magnetic field of planet Mercury. One of the possible dynamo scenarios is a dynamo with feedback from the magnetosphere. Due to its weak magnetic field

Relative Contributions of Lower‐Atmosphere Tidal and Solar‐Magnetospheric Forcings to the Day‐to‐Day Variability of F‐Region Electron Density

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract We use Thermosphere Ionosphere Electrodynamics General Circulation Model simulations nudged to realistic tides and their statistical day‐to‐day variabilities (DTDVs), derived from Michelson Interferometer for Global High‐Resolution Thermospheric Imaging/Ionospheric Connection Explorer observations, to estimate the relative importance of tidal ...

Geomagnetic Disturbances Due To Neutral‐Wind‐Driven Ionospheric Currents

Space Weather
Previous simulation efforts on geomagnetic disturbances (GMDs) and geomagnetically induced currents (GICs) mostly rely on global magnetohydrodynamics models, which explicitly calculate the magnetospheric currents and carry certain assumptions about the ...

Chapman Conference on Magnetospheric Currents

Eos, Transactions American Geophysical Union, 1983
A Chapman Conference on Magnetospheric Currents was held in Irvington, Va, during April 5–8, 1983. The purpose of this conference was to bring together theoretical and experimental researchers and students interested in electric currents in the earth's and other planets′ magnetospheres.

Constraining Electron‐Impact Ionization of O2 Through UV Aurora Observations at Ganymede

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract While photoionization rates of Ganymede's O2 ${\mathrm{O}}_{2}$ dominated atmosphere are well constrained, the contribution of electron‐impact ionization is rather uncertain. Previous quantitative estimates have relied on assumptions about densities and energy distributions of precipitating electrons, or on rare spacecraft measurements that ...
