Journal ArticleDOI
Structure and dynamics of magnetic reconnection for substorm onsets with Geotail observations
T. Nagai,M. Fujimoto,Yoshitaka Saito,Shinobu Machida,Toshio Terasawa,Rumi Nakamura,Tadashi Yamamoto,Toshifumi Mukai,Atsuhiro Nishida,Susumu Kokubun +9 more
TL;DR: In this paper, the structure and dynamics of magnetic reconnection were studied in the premidnight sector of the magnetotail at 20-30 RE for substorm onsets in Geotail observations.
Journal ArticleDOI
Geotail observations of the Hall current system: Evidence of magnetic reconnection in the magnetotail
T. Nagai,Iku Shinohara,M. Fujimoto,Masahiro Hoshino,Yoshitaka Saito,Shinobu Machida,Toshifumi Mukai +6 more
TL;DR: In a two-fluid picture of magnetic reconnection, inflow electrons flow with the magnetic field line to the diffusion region, whereas inflow ions cannot reach the diffusion regions and rest around a distance of the ion inertial length as discussed by the authors.
Journal ArticleDOI

Argall,Barbara L. Giles,Thomas E. Moore,Frederick Wilder,Robert J. Strangeway,Christopher T. Russell,Per-Arne Lindqvist,Werner Magnes +31 more
TL;DR: Observations of electron-scale current sheets in Earth’s turbulent magnetosheath reveal electron reconnection without ion coupling, contrary to expectations from the standard model of magnetic reconnection.
Journal ArticleDOI
Statistical analysis of the plasmoid evolution with Geotail observations
Akimasa Ieda,Shinobu Machida,Toshifumi Mukai,Yoshitaka Saito,Tadashi Yamamoto,Atsuhiro Nishida,Toshio Terasawa,Susumu Kokubun +7 more
TL;DR: In this article, the authors used low energy particle (LEP) and magnetic field (MGF) data from the Geotail spacecraft to study the evolution of plasmoids in the Earth's magnetotail.
Journal ArticleDOI
Plasma entry from the flanks of the near-Earth magnetotail: Geotail observations
M. Fujimoto,Toshio Terasawa,Toshifumi Mukai,Yoshitaka Saito,Tatsundo Yamamoto,Susumu Kokubun +5 more
TL;DR: In this paper, the authors detect cold-dense plasma in the low-latitude boundary layer (LLBL) in the near-Earth tail flanks of a spacecraft.
