We present the results of a multi-event study of the normalized reconnection rate integrating events spanning the three primary regimes of reconnection observed by the Magnetospher…
Relativistic Electron Acceleration and the 'Ankle' Spectral Feature in Earth's Magnetotail Reconnection
Weijie Sun, Mitsuo Oka, Marit Øieroset +14
Electrons are accelerated to high, non-thermal energies during explosive energy-release events in space, such as magnetic reconnection. However, the properties and acceleration mec…
Outstanding questions and future research of magnetic reconnection
R. Nakamura, J. L. Burch, J. Birn +22
This short article highlights the unsolved problems of magnetic reconnection in collisionless plasma. The advanced in-situ plasma measurements and simulations enabled scientists to…
Ohm's Law, the Reconnection Rate, and Energy Conversion in Collisionless Magnetic Reconnection
Yi-Hsin Liu, Michael Hesse, Kevin Genestreti +12
Magnetic reconnection is a ubiquitous plasma process that transforms magnetic energy into particle energy during eruptive events throughout the universe. Reconnection not only conv…
Out-of-plane Parallel Current in the Diffusion Regions: The Interaction Between Diffusion Region Systems and their Impact on the Outer EDR
Jason M. H. Beedle, Daniel J. Gershman, Vadim M. Uritsky +5
Dayside magnetic reconnection allows for the transfer of the solar wind's energy into Earth's magnetosphere. This process takes place in electron diffusion regions (EDRs) embedded…
Field-Aligned Current Structures during the Terrestrial Magnetosphere's Transformation into Alfven Wings and Recovery
Jason M. H. Beedle, Li-Jen Chen, Jason R. Shuster +8
On April 24th, 2023, a CME event caused the solar wind to become sub-Alfvenic, leading to the development of an Alfven Wing configuration in the Earth's Magnetosphere. Alfven Wings…
Earth's Alfvén wings driven by the April 2023 Coronal Mass Ejection
Li-Jen Chen, Daniel Gershman, Brandon Burkholder +33
We report a rare regime of Earth's magnetosphere interaction with sub-Alfvénic solar wind in which the windsock-like magnetosphere transforms into one with Alfvén wings. In the mag…
Multi-scale observation of magnetotail reconnection onset: 2. microscopic dynamics
K. J. Genestreti, C. Farrugia, S. Lu +23
We analyze the local dynamics of magnetotail reconnection onset using Magnetospheric Multiscale (MMS) data. In conjunction with MMS, the macroscopic dynamics of this event were cap…
Multi-scale observation of magnetotail reconnection onset: 1. macroscopic dynamics
K. J. Genestreti, C. Farrugia, S. Lu +22
We analyze a magnetotail reconnection onset event on 3 July 2017 that was observed under otherwise quiescent magnetospheric conditions by a fortuitous conjunction of six space and…
First-Principles Theory of the Rate of Magnetic Reconnection in Magnetospheric and Solar Plasmas
Yi-Hsin Liu, Paul Cassak, Xiaocan Li +3
The rate of magnetic reconnection is of the utmost importance in a variety of processes because it controls, for example, the rate energy is released in solar flares, the speed of…
