Simultaneous Mars-orbit observations reveal Kelvin-Helmholtz instability-driven bulk atmospheric ion escape
Chi Zhang, Chuanfei Dong, Gangkai Poh +11
Atmospheric ion escape driven by the solar wind is a key process controlling the long-term loss of the Martian atmosphere. Localized plasma clouds can carry substantial fluxes of p…
Direct Observations of Magnetic Reconnection in the Solar Wind Current Sheets near Mars
Chi Zhang, Chuanfei Dong, Xinmin Li +10
Magnetic reconnection is a fundamental and ubiquitous process in astrophysical plasmas that converts magnetic energy into plasma kinetic and thermal energy. Throughout the heliosph…
Spectral Properties and Energy Injection in Mercury's Magnetotail Current Sheet
Xinmin Li, Chuanfei Dong, Liang Wang +8
Mercury's magnetotail hosts a thin and highly dynamic current sheet (CS), where magnetic reconnection and strong fluctuations frequently occur. Here, we statistically analyze magne…
Revisiting Mars' Induced Magnetic Field and Clock Angle Departures under Real-Time Upstream Solar Wind Conditions
Zhihao Cheng, Chi Zhang, Chuanfei Dong +5
Mars lacks a global intrinsic dipole magnetic field, but its interaction with the solar wind generates a global induced magnetosphere. Until now, most studies have relied on single…
Physics-Informed Neural Networks for Modeling the Martian Induced Magnetosphere
Jiawei Gao, Chuanfei Dong, Chi Zhang +6
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.…
Planar Collisionless Shock Simulations with Semi-Implicit Particle-in-Cell Model FLEKS
Hongyang Zhou, Yuxi Chen, Chuanfei Dong +4
This study investigates the applicability of the semi-implicit particle-in-cell code FLEKS to heliospheric shock simulations. We examine one- and two-dimensional local planar shock…
