Journal ArticleDOI
Ion heating by strong electrostatic ion cyclotron turbulence
TL;DR: In this paper, a theory of ion heating due to electrostatic ion cyclotron (EIC) waves in the auroral zone is presented, and an upper bound on the heating rate is derived using a time-average model of ion dynamics in the coherent waves.
Journal ArticleDOI
Comparisons of Polar satellite observations of solitary wave velocities in the plasma sheet boundary and the high altitude cusp to those in the auroral zone
Cynthia A Cattell,J. Dombeck,John R. Wygant,Mary K. Hudson,F. S. Mozer,M. Temerin,W. K. Peterson,Craig Kletzing,Christopher T. Russell,Robert F. Pfaff +9 more
TL;DR: In this article, it was shown that, at high altitude, the solitary waves are positive potential structures (electron holes), with scale sizes of the order of 10's of Debye lengths, which usually propagate with velocities of a few thousand km/s.
Journal ArticleDOI
Experimental evidence on the role of the large spatial scale electric field in creating the ring current
TL;DR: In this paper, the authors present the first simultaneous in situ measurements of the large-scale convection electric field and the ring current induced magnetic field perturbations in the equatorial plane of the inner magnetosphere and compares them to the evolution of major geomagnetic storms as characterized by Dst.
Journal ArticleDOI
Simulations of radiation belt formation during storm sudden commencements
Mary K. Hudson,Scot R. Elkington,John G. Lyon,Victor A. Marchenko,Ilan Roth,M. Temerin,J. B. Blake,M. S. Gussenhoven,John R. Wygant +8 more
TL;DR: In this paper, the effect of solar wind on particle energization of varying solar wind and model pulse parameters is investigated, and the inner boundary and stability of the newly formed belt depends on the magnitude of radial transport at the time of formation and subsequent ring current perturbation of adiabatic trapping.
