C. P. Escoubet,Jean Berchem,J. M. Bosqued,Karlheinz Trattner,Matthew Taylor,Frederic Pitout,C. Vallat,H. E. Laakso,Arnaud Masson,M. W. Dunlop,H. Rème,Iannis Dandouras,Andrew Fazakerley +12 more
TL;DR: In this paper, the authors used a three-dimensional magnetohydrodynamic (MHD) simulation to display the topology of the magnetic field and locate the sources of the ions during the double cusp event.

TL;DR: In this paper, the authors used the Curlometer technique to estimate the thickness of the current layer of a planar current array and the boundary crossing times, which can be used to calculate a number of other properties such as the dimensionality of the structure and the corresponding velocity, the field curvature, or boundary normals.

TL;DR: In this article, a case study on the formation of the CDPS utilizing a wide variety of space and ground-based observations, but primarily from the Double Star and Polar spacecraft on December 5th, 2004, is presented.
Source location of the wedge‐like dispersed ring current in the morning sector during a substorm
Masatoshi Yamauchi,Pontus Brandt,Yusuke Ebihara,Iannis Dandouras,Holger Nilsson,Rickard Lundin,H. Rème,C. Vallat,P.-A. Lindquvist,André Balogh,P. W. Daly +10 more
TL;DR: The wedge-like dispersed ring current in the morning sector during a substorm was studied in this paper, where it was shown that the wedge-shaped ring current can be seen as a wave.
