Towards a precise modelling of transport processes in planetary ionospheres: photoelectrons, magnetospheric electrons and protons [PDF]

, 2008
session C13Numerical simulations of planetary ionospheres (Earth, Mars, Venus and Titan) using Boltzmann's kinetic formalism have proved their efficiency in interpreting multi-instrumental data sets. We present now the last evolution of the Trans-* codes

Observation of CO2++ dication in the dayside Martian upper atmosphere

Earth and Planetary Physics, 2020
Doubly charged positive ions (dications) are an important component of planetary ionospheres because of the large energy required for their formation.

First Report of Rising‐Tone EMIC Waves Driven by the Magnetosheath High‐Speed Jet

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Magnetosheath high‐speed jets (HSJs) are pervasive transient structures with enhanced dynamic pressure in the terrestrial magnetosheath and can exert notable local impacts on the magnetopause. Although various geoeffects have been reported to be associated with HSJs, whether HSJs can drive the generation of electromagnetic ion cyclotron (EMIC)

All Ionospheres are not Alike: Reports from other Planets [PDF]

, 1995
Our understanding of planetary ionospheres made some progress during the last four years. Most of this progress was due to new and/or improved theoretical models, although some new data were also obtained by direct and remote sensing observations.

Enhancement of Dayside Westward Electrojet: Triggering Conditions and Current Closures

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Geomagnetic substorms are a major path for energy storage and release in the magnetosphere, which typically occur in the midnight sector with a strong enhancement of westward electrojets. However, by analyzing 37,940 events from a substorm list, about 3% of events unexpectedly initiated in the noon sector.

H2 Chemistry and Protonation in the Dayside Venusian Upper Atmosphere

The Astronomical Journal
Although H _2 is present in low concentrations, it critically controls the structure and composition of planetary upper atmospheres through protonation under solar extreme-ultraviolet and soft X-ray irradiation. Recent studies highlight the importance of

Ultra‐Low‐L Sub‐MeV Electron Microbursts During the May 2024 Super Storm

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract During the May 2024 super storm, we identified sub‐second microburst‐type relativistic electron precipitation events at McIlwain's L∼2 $L\sim 2$ in low‐Earth orbit using the Gamma‐ray Burst Monitor (CGBM) onboard the CALorimetric Electron Telescope on the International Space Station.
