Comparative Analysis of the Primary Drivers of Plasma Sheet Electron Precipitation

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Plasma sheet electron precipitation into Earth's atmosphere plays a key role in magnetosphere–ionosphere coupling at auroral latitudes. Such precipitation can be driven by four primary mechanisms that scatter equatorial electrons into the loss cone: resonant interactions with whistler‐mode waves, electron cyclotron harmonics (ECH), broadband ...

Energy limits of electron acceleration in the plasma sheet during substorms: A case study with the Magnetospheric Multiscale (MMS) mission

Geophysical Research Letters, 2016
We present multipoint observations of earthward moving dipolarization fronts and energetic particle injections from NASA's Magnetospheric Multiscale mission with a focus on electron acceleration.

Observation of Interchange Reconnection on Mars

The Astrophysical Journal, 2023
Without a global dipole magnetic field, Mars has magnetic anomalies, i.e., crustal fields, in the southern hemisphere and interesting flexible magnetic fields in the magnetotail.

MMS Observation of Trapping of Electrons by Chorus Waves Inside a Magnetic Hole

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract We present an event of chorus waves embedded within a magnetic hole (MH) in the Earth's magnetosheath, observed by the Magnetospheric Multi‐Scale (MMS) mission on 1 March 2016. Unlike conventional cases where chorus waves are typically detected near the center of a magnetic depression, in this event lower‐band chorus waves appear predominantly

Quantitative magnetotail characteristics of different magnetospheric states [PDF]

Annales Geophysicae, 2004
Quantitative relationships allowing one to compute the lobe magnetic field, flaring angle and tail radius, and to evaluate magnetic flux based on solar wind/IMF parameters and spacecraft position are obtained for the middle magnetotail, X=(–15,–35)RE ...

Formation of Continuum Emission Structures Associated With the Aurora

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Recent observations enabled by improvements in geospace remote‐sensing instrumentation have revealed the spatial structure of continuum emissions that appear to be associated with the aurora, but little is known about the formation and drivers of these structures.

Dipolarization fronts in the near-Earth space and substorm dynamics [PDF]

Annales Geophysicae, 2015
During magnetospheric substorms and plasma transport in the Earth's magnetotail various magnetic structures can be detected. Dipolarization fronts and flux ropes are the most prominent structures characteristic for substorm dynamics. However, they are

Characterizing Ion‐Scale Fluctuations Around Dipolarization Fronts in Earth's Magnetotail

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract In the Earth's magnetotail bursty bulk flows are often associated with dipolarizing magnetic flux bundles. The leading edges of such earthward‐moving flux bundles are called dipolarization fronts (DF). In the present study we investigate the characteristics of ion‐scale oscillations embedded inside DFs, using observations from NASA's ...

Magnetospheric Sources of Theta Aurora: A Case Study Comparing Observations With SWMF Global Simulation

Geophysical Research Letters
We present the first high resolution global MHD with coupled inner magnetosphere simulation results of an observed theta aurora event. We use the Space Weather Modeling Framework in the Geospace configuration, which produces accurate field aligned ...

Two‐Dimensional Equilibrium Model of Planetary Magnetotail in Generalized Nonthermal Plasmas

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Solar wind‐magnetosphere interaction may result in an elongated magnetotail with stored magnetic field energy. This study presents for the first time a family of asymptotic solutions for stretched two‐dimensional magnetotail equilibrium in generalized nonthermal plasmas, including the Kappa‐like and Maxwellian‐like velocity distributions with ...
