Cross-scale Dynamics Driven by Plasma Jet Braking in Space

C. M. Liu et al.

Summary: This study reports the first observation of cross-scale dynamics driven by jet braking in geospace using high-cadence data from NASA's Magnetospheric Multiscale Mission. The study reveals that jet braking leads to MHD-scale distortion of magnetic field lines, development of an ion-scale jet front with strong Hall electric fields, and generation of intense electron-scale field-aligned currents and Debye-scale turbulence. These findings contribute to understanding the transfer of energy in large-scale structures to small-scale structures in space.

Subion-Scale Flux Rope Nested Inside Ion-Scale Flux Rope in Earth's Magnetotail

R. J. He et al.

Summary: This study presents the first observation of a subion-scale MFR nested in an ion-scale MFR, revealing that the subion-scale MFR exhibits more intense plasma activity than the ion-scale MFR, potentially due to 3D magnetic reconnection. These findings may provide new insights into understanding energy cascade in space plasmas.

First Observation of Magnetic Flux Rope Inside Electron Diffusion Region

Z. Z. Chen et al.

Summary: This study presents the first observation of a magnetic flux rope (MFR) inside an electron diffusion region (EDR), confirming its crucial role in magnetic reconnection. By observing and analyzing the structure and energy dissipation of MFR, it helps to understand the modulation of the electric field in EDR by MFR.

Efficient Nonthermal Ion and Electron Acceleration Enabled by the Flux-Rope Kink Instability in 3D Nonrelativistic Magnetic Reconnection

Qile Zhang et al.

Summary: Research shows that the flux-rope kink instability leads to strong field-line chaos in weak-guide-field regimes, allowing particles to transport more efficiently out of flux ropes and undergo acceleration. The results are highly relevant to observations of nonthermal particle acceleration in space and astrophysics.

Kinetics of Magnetic Hole Behind Dipolarization Front

C. M. Liu et al.

Summary: Using high-resolution data from the Magnetospheric Multiscale Mission, the generation of magnetic holes by electron mirror instability behind dipolarization fronts has been observed. These magnetic holes are sustained by electron flow vortex at sub-proton scale and contain strong field-aligned currents, contributing to magnetosphere-ionosphere coupling. Additionally, they demonstrate efficient energy conversion and cross-scale coupling.

Microscale Processes Determining Macroscale Evolution of Magnetic Flux Tubes along Earth's Magnetopause

K. -J. Hwang et al.

Summary: Nonsteady dayside magnetic reconnection at the magnetopause, evidenced by flux transfer events (FTEs), is an important process affecting solar wind-Earth's magnetosphere coupling. A recent study shows that FTEs can consist of two flux tubes with different topology, with local kinetic processes affecting their macroscale characteristics and evolution.

Non-Adiabatic Electron Heating in the Magnetic Islands During Magnetic Reconnection

Keizo Fujimoto et al.

Summary: A new mechanism for strong electron heating in magnetic islands ejected from the reconnection current layer is proposed in this study. Full kinetic simulations in a three-dimensional system show that electrons are effectively accelerated by the non-ideal electric field generated through electromagnetic turbulence in the magnetic islands. High-energy electrons are efficiently scattered by the turbulence, leading to strong electron heating, which is consistent with recent satellite observations in the Earth's magnetosphere.
