Field‐Aligned Anisotropy of Electrons in Magnetic Hole Behind the Dipolarization Front in the Flow Braking Region

Y. Y. Wei, S. Y. Huang, K. Jiang, Zhigang Yuan et autres

Abstract Magnetic holes (MHs) are magnetic structures characterized by a depression of magnetic field strength and have been frequently observed around dipolarization fronts (DFs), which are characterized by the increase in the magnetic field B z . Both MHs and DFs are …

Induced magnetosphere of Mars responds fast to interplanetary magnetic field rotation

R. T. Lin, Jingyi Zhou, S. Y. Huang, Zhigang Yuan et autres

Interactions between the ionospheres of unmagnetized bodies and ambient plasma flows form induced magnetospheres. The induced magnetosphere is generally affected by external magnetic fields. Observations of response processes of the induced magnetosphere to external magnetic fields are important for understanding global dynamical …

Complexity of Magnetic Field Fluctuations in the Reconnection Outflow Region

S. Y. Huang, H. W. Zhan, Q. Y. Xiong, Zhigang Yuan et autres

Abstract Magnetic reconnection is a fundamental process that rapidly converts magnetic energy into plasma kinetic and thermal energy, and generates high-speed outflows. Within the reconnection outflow region, electromagnetic fields, plasma density, and flow velocity exhibit strong fluctuations that may interact nonlinearly with …

Tearing Instability of Weakly Anisotropic Embedded Thin Current Sheets in Space Plasmas

H. W. Zhan, S. Y. Huang, Q. Y. Xiong, Gang Li et autres

Abstract Current sheets are widely observed in the solar wind and planetary magnetosphere, where they play a fundamental role in magnetic reconnection, plasma heating, and turbulence evolution. A novel equilibrium current sheet model has been developed that incorporates a thin ion-scale current …

Impact of Cold Ions on Reconnection Fronts During Magnetic Reconnection

S. Y. Huang, S. Y. Yan, Q. Y. Xiong, Zhigang Yuan et autres

Abstract Reconnection fronts (RFs) are crucial structures formed by magnetic reconnection. However, the effects of cold ions on RFs are not clear until now. In this study, we investigated their impact using 2D kinetic particle‐in‐cell simulations. Our results show that colder ions …

Alpha-particle Heating and Anisotropy in Solar Wind Turbulence: Insights from Parker Solar Probe Observations and Particle-in-cell Simulations

Q. Y. Xiong, S. Y. Huang, Z X Yuan, Gang Li et autres

Abstract Alongside protons, alpha particles make up a crucial part of the solar wind’s ion population, playing an important role in turbulent energy conversion and ion-scale heating. However, the physical processes governing their temperature evolution, anisotropy development, and differential streaming remain incompletely …

In Situ Observations of Outer Electron Diffusion Region in the Magnetotail

Yaqin Tang, S. Y. Huang, K. Jiang, Zhigang Yuan et autres

Abstract The electron diffusion region (EDR), which can be divided into inner and outer EDR, is the crucial region where the magnetic field topology changes and strong energy conversion between fields and plasmas occurs during magnetic reconnection. The outer EDR is characterized …

Global current systems in the magnetosphere of Mercury

R. T. Lin, S. Y. Huang, Zhigang Yuan, J. A. Slavin et autres

The global current systems of a planet represent electrodynamic interactions between its different parts, and between its magnetosphere and the ambient solar wind. Although some local currents of Mercury's magnetosphere have already been revealed by previous observational studies, the global picture of …

Direct Observations of Acceleration of Planetary Ions From Mars' Ionosphere Through Magnetic Reconnection When IMF Rotates

R. T. Lin, S. Y. Huang, Yuming Wang, Q. Y. Xiong et autres

Abstract Mars lacks an intrinsic global magnetic field but possesses crustal magnetic anomalies and an atmosphere. Mars' ionosphere, resulted from interactions between Mars' atmosphere and solar radiation, directly interacts with solar wind and interplanetary magnetic field (IMF). However, the mechanisms governing ion …
