Periodic Density Structures Observed in Ulysses Data: First Results

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Periodic density structures (PDSs) are advecting quasi‐periodic (periodicities between several minutes and several hours) density enhancements observed in the solar wind and corona. There is strong evidence that PDSs are formed at the Sun.

JWST/NIRSpec Reveals the Atmospheric Driver of Saturn's Variable Magnetospheric Rotation Rate

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Past measurements of Saturn's upper atmosphere have allowed only a broad scale view of the temperature and ion density structures within the auroral region. However, Saturn's auroral currents include a planetary period current component that is produced by neutral atmospheric flows.

Cold ions of ionospheric origin observed at the dayside magnetopause and their effects on magnetic reconnection [PDF]

, 2015
Thesis (Ph.D.) University of Alaska Fairbanks, 2015Magnetic reconnection at the dayside magnetopause is one of the most important mechanisms that efficiently transfers solar wind particles, momentum, and energy into the magnetosphere.

Fast Shocks From Magnetic Reconnection Outflows

, 2011
Magnetic reconnection is commonly perceived to drive flow and particle acceleration in flares of solar, stellar, and astrophysical disk coronae but the relative roles of different acceleration mecha- nisms in a given reconnection environment are not well

JET Formation in Solar Atmosphere Due to Magnetic Reconnection

The Astrophysical Journal, 2017
Using numerical simulations, we show that jets with features of type II spicules and cold coronal jets corresponding to temperatures $10^{4}$ K can be formed due to magnetic reconnection in a scenario in presence of magnetic resistivity. For this we model the low chromosphere-corona region using the C7 equilibrium solar atmosphere model and assuming ...

An Investigation on the Apparent North‐South Asymmetry Identified in Multiple Current Sheet Crossing Events in Jovian Dawn Outer Magnetosphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Jovian magnetospheric dynamics are often believed to be mainly controlled by internal elements such as Jupiter's strong and fast‐rotating magnetic moment and Io's abundant volcanic escape, as these internal elements are powerful enough to control the magnetospheric dynamics, contrary to the internal elements of the earth's magnetosphere.

Ion Energization and Acceleration Associated With Foreshock Bubbles: Results From a Hybrid‐Vlasov Simulation and MMS Observations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Foreshock Bubbles (FBs) are large‐scale transient structures found in Earth's foreshock region and are associated with foreshock‐discontinuity interaction. FBs play a significant role in accelerating and energizing plasma through various mechanisms.

Theory and Applications of Non-Relativistic and Relativistic Turbulent Reconnection

, 2015
Realistic astrophysical environments are turbulent due to the extremely high Reynolds numbers. Therefore, the theories of reconnection intended for describing astrophysical reconnection should not ignore the effects of turbulence on magnetic reconnection.

3D MHD Simulations of Coronal Loops Heated via Magnetic Braiding. II. Automatic Detection of Reconnection Outflows and Statistical Analysis of Their Properties

The Astrophysical Journal
Recent observations of fast and bursty “nanojets” suggest novel diagnostics of nanoflare heating in the solar corona. The aim of this work is to investigate the presence and properties of reconnection outflows, similar to observed nanojets, in numerical ...

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
