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.

First Observation of the Second Harmonic of Upper Band Chorus Waves Linking to Slow Z‐Mode

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The Z‐mode, comprising fast and slow branches, is a ubiquitous electromagnetic wave in planetary magnetospheres. While fast Z‐mode generation is attributed to electron cyclotron maser instability, the slow Z‐mode mechanism remains unresolved.

Electron Energization within an Ion-scale Flux Rope Chain in Earth’s Turbulent Magnetotail Plasma Sheet

The Astrophysical Journal
Flux ropes in space plasma can play an important role in particle acceleration. However, the mechanisms of electron energization and the resulting electron energy distribution associated with flux ropes are still not fully understood. This study examines

Global Occurrence of Solitary Waves in the Martian Magnetosphere

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract This letter presents a global occurrence of bipolar solitary waves (SWs) in the Martian magnetosphere. We utilized medium‐frequency electric field measurements from October 2014 to December 2023 from the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft.

Steady-State Magnetohydrodynamic Flow Around an Unmagnetized Conducting Sphere [PDF]

, 2014
The non-collisional interaction between conducting obstacles and magnetized plasma winds can be found in different scenarios, from the interaction occurring between regions inside galaxy clusters to the interaction between the solar wind and Mars, Venus,

The Incompressible Magnetohydrodynamic Energy Cascade Rate Upstream of Mars: Effects of the Total Energy and the Cross-helicity on Solar Wind Turbulence

The Astrophysical Journal
Solar wind turbulence is a dynamical phenomenon that evolves with heliocentric distance. Orbiting Mars since 2014 September, Mars Atmosphere and Volatile EvolutioN offers a unique opportunity to explore some of its main properties beyond ∼1.38 au.

Physics‐Informed Neural Networks for Modeling the Martian Induced Magnetosphere

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Understanding the magnetic field environment around Mars and its response to upstream solar wind conditions provide key insights into the processes driving atmospheric ion escape. To date, global models of Martian induced magnetosphere have been exclusively physics‐based, relying on computationally intensive simulations. For the first time, we

How the Relative Contribution of DP‐1 and DP‐2 Currents Reshapes the Global Current System During Substorms

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Geomagnetic disturbances in polar regions can be decomposed into two main patterns: the Disturbance Polar (DP) 1 and 2. How their relative contribution reshapes global current system remains unclear. In this study, we classified substorms from 2010 to 2022 into weak and strong DP‐2 events based on the ratio of the eastward to westward auroral ...
