Spatial Scales of Electron Density Fluctuations in the Martian Ionosphere
The Astrophysical JournalIn recent Martian ionospheric studies, the spatial scales of electron density irregularities have been computed using magnetic field measurements by treating these fluctuations as electromagnetic.

Hall Fields and Current Systems of Magnetic Reconnection under Asymmetric Conditions
The Astrophysical Journal, 2023 The Hall effect is a key component of collisionless reconnection. A previous study showed that a quadrupolar Hall pattern under symmetric conditions degenerates into a bipolar pattern under highly asymmetric conditions.

Reconfiguration of Mercury's Exosphere During Strong Space Weather Events
Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Mercury is exposed to various space weathering processes, which alter the surface and cause emission of atoms and molecules into the exosphere. The exosphere thus allows remote insights into the surface composition and erosion processes, with the emission of refractory elements such as Ca and Mg typically being dominated by micrometeoroid ...

An Estimate of the Importance of Electron-stimulated Desorption of Sodium at Mercury
The Planetary Science JournalWe revisit the importance of electron-stimulated Desorption (ESD) as a source of neutral sodium (Na) atoms and Na ^+ ions in Mercury’s exosphere and ionosphere.

The Influence of Surface Binding Energy on Sputtering in Models of the Sodium Exosphere of Mercury
The Planetary Science Journal, 2022 We have simulated the sodium (Na) exosphere of Mercury to show how the exosphere is affected by the assumed surface binding energy (SBE) of Na in the sputtered component.

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Microbursts are thought to be a key contributor to radiation belt electron loss, with chorus waves considered a primary driver of this precipitation. However, the conditions under which chorus waves produce MeV electron loss remain poorly constrained.

Planetary magnetospheres [PDF]
, 1981 A concise overview is presented of our understanding of planetary magnetospheres (and in particular, of that of the Earth), as of the end of 1981. Emphasis is placed on processes of astrophysical interest, e.g., on particle acceleration, collision-free ...

Acceleration in Exoplanet Magnetospheres
, 2023 We briefly review the various acceleration mechanisms working in exoplanetary magnetospheres. The proposed scenarios are based on the investigation of planetary magnetospheres of the Solar System.

Power Spectral Characteristics of Martian Ionospheric Irregularities
The Astrophysical JournalThe intrinsic magnetic field of a planet plays a key role in its ionospheric dynamics. Mars lacks a global magnetic field, thus ionospheric plasma is weakly coupled to crustal and induced magnetic field.
