THEMIS observations of an earthward‐propagating dipolarization front

A Runov, V Angelopoulos, MI Sitnov… - Geophysical …, 2009 - Wiley Online Library
We report THEMIS observations of a dipolarization front, a sharp, large‐amplitude increase
in the Z‐component of the magnetic field. The front was detected in the central plasma sheet …

On the current sheets surrounding dipolarizing flux bundles in the magnetotail: The case for wedgelets

J Liu, V Angelopoulos, A Runov… - Journal of Geophysical …, 2013 - Wiley Online Library
Using Time History of Events and Macroscale Interactions during Substorms observations
from four tail seasons, we study the three‐dimensional structure of the dipolarization front …

A THEMIS multicase study of dipolarization fronts in the magnetotail plasma sheet

A Runov, V Angelopoulos, XZ Zhou… - Journal of …, 2011 - Wiley Online Library
We discuss results of a superposed epoch analysis of dipolarization fronts, rapid (δt< 30 s),
high‐amplitude (δBz> 10 nT) increases in the northward magnetic field component …

Electromagnetic energy conversion at reconnection fronts

V Angelopoulos, A Runov, XZ Zhou, DL Turner… - science, 2013 - science.org
Earth's magnetotail contains magnetic energy derived from the kinetic energy of the solar
wind. Conversion of that energy back to particle energy ultimately powers Earth's auroras …

Energetic electron acceleration by unsteady magnetic reconnection

HS Fu, YV Khotyaintsev, A Vaivads, A Retinò, M André - Nature Physics, 2013 - nature.com
The mechanism that produces energetic electrons during magnetic reconnection is poorly
understood. This is a fundamental process responsible for stellar flares,, substorms,, and …

Bursty bulk flows and dipolarization in MHD simulations of magnetotail reconnection

J Birn, R Nakamura, EV Panov… - Journal of Geophysical …, 2011 - Wiley Online Library
Using three‐dimensional MHD simulations of magnetic reconnection in the magnetotail, we
investigate the fate of earthward bursty bulk flows (BBFs). The flow bursts are identified as …

Dipolarization fronts as a consequence of transient reconnection: In situ evidence

HS Fu, JB Cao, YV Khotyaintsev… - Geophysical …, 2013 - Wiley Online Library
Dipolarization fronts (DFs) are frequently detected in the Earth's magnetotail from XGSM=−
30 RE to XGSM=− 7 RE. How these DFs are formed is still poorly understood. Three …

Occurrence rate of earthward‐propagating dipolarization fronts

HS Fu, YV Khotyaintsev, A Vaivads… - Geophysical …, 2012 - Wiley Online Library
The occurrence rate of earthward‐propagating dipolarization fronts (DFs) is investigated in
this paper based on the 9 years (2001–2009) of Cluster 1 data. For the first time, we select …
