The temporal evolution of a small auroral substorm as viewed from high altitudes with Dynamics Explorer 1 by J. D Craven( Book )

2 editions published in 1985 in English and held by 75 WorldCat member libraries worldwide

"A small auroral substorm is investigated with auroral imaging photometers carried on the spacecraft Dynamics Explorer 1. Initial brightening along the auroral oval and the subsequent westward and poleward motions of intense, localized emission regions are associated with auroral surges. Following substorm onset, another region of less intense emissions is observed to develop at lower latitudes and adjacent to the bright region near local midnight. This second region expands towards the east. The bright zone of auroral emissions associated with the surges is interpreted as the signature of electron acceleration along magnetic field lines threading the boundary layer of the plasma sheet in the magnetotail. The more diffuse, less intense region is identified with eastward-drifting electrons injected into the plasma sheet and ring current following substorm onset. No rapid poleward motion of the discrete aurora is detected during substorm recovery."--NTRS abstract
Periodic substorm activity in the geomagnetic tail by C. Y Huang( Book )

3 editions published in 1983 in English and held by 74 WorldCat member libraries worldwide

On 19 May 1978 an unusual series of events is observed with the Quadrispherical LEPEDEA on board the ISEE-1 satellite in the earth's geomagnetic tail. For 13 hours periodic of both bursts of both ions and electrons are seen in all the particle detectors on the spacecraft. On this day periodic activity is also seen on the ground, where multiple intesifications of the electrojets are observed. At the same time the latitudinal component of the interplanetary magnetic field shows a number of strong southward deflections. We conclude that an extended period of substorm activity is occurring, which causes repeated thinnings and recoveries of the plasma sheet. These are detected by ISEE, which is situated in the plasma sheet boundary layer, as periodic dropouts and reappearances of the plasma. Comparisons of the observations at ISEE with those at IMP-8, which for a time is engulfed by the plasma sheet, indicate that the activity is relatively localized in spatial extent. For this series of events it is clear that a global approach to magnetospheric dynamics, e.g., reconnection, is inappropriate. (Author)
Global auroral responses to magnetospheric compressions by shocks in the solar wind : two case studies( Book )

3 editions published in 1985 in English and held by 73 WorldCat member libraries worldwide

Two case studies are presented of the global auroral responses to shocks in the solar wind at Earth. The z component of the interplanetary magnetic field, Bz, is negative ahead and behind the first shock and positive for the second case. A sudden-commencement geomagnetic storm develops in each case, with maximum D sub st somewhat <190 nT. An immediate auroral response is detected at all longitudes around the auroral oval, in which auroral luminosities increase by a factor of 2-3 with the first samples after each sudden commencement. The time delay in obtaining the first sample varies with local time from about 1 to 18 minutes. No other significant variations in the aurora are associated with the immediate response. Beginning about 30 minutes after each sudden commencement, the aurora becomes active and displays significant variations in its luminosity and spatial distribution. For Bz <0 an intense substorm develops. A sun-aligned transpolar arc forms when Bz> 0, appearing first at local midnight as a polar arc and then lengthening sunward from the auroral oval across the polar cap to noon at an average speed of about 1 km/sec

On the distributions of plasmas and electric fields over the auroral zones and polar caps by Louis A Frank( Book )

1 edition published in 1971 in English and held by 4 WorldCat member libraries worldwide

Simultaneous observations of DC electric fields and low-energy charged particles at low altitudes over the earth's auroral zones and polar caps were obtained with the satellite Injun 5. Several of the principal results for the evening and dawn local time sectors are summarized
Entry of low-energy solar protons into the earth's magnetotail by Nicolaos A Saflekos( Book )

1 edition published in 1975 in English and held by 4 WorldCat member libraries worldwide

The access of low-energy solar protons (E sub p> 0.3 MeV) from the interplanetary medium into the earth's magnetotail was studied using observations obtained by Explorers 33, 34, and 35 over a 4.5 year period. Emphasis is on events whose intensity-time profiles exhibit sharply defined discontinuities observed by at least one of the three spacecraft in the interplanetary medium and another within the magnetotail

Drift of noninteracting charged particles in a simple geomagnetic field by M. A Schield( Book )

1 edition published in 1969 in English and held by 4 WorldCat member libraries worldwide

The corotation of plasmas within the plasmasphere has been observed and the existence of a potential difference across the magnetosphere in the dawn-dusk meridian of several tens of kilovolts is consistent with various geophysical observations. The purpose of the paper is to solve analytically the drift motion of noninteracting charged particles, mirroring equatorially in a rotating magnetic dipole-field, across which is superimposed a uniform electric field

Configuration space Faddeev calculations( )

1 edition published in 1992 in English and held by 0 WorldCat member libraries worldwide

The detailed study of few-body systems provides one of the most precise tools for studying the dynamics of nuclei and nucleons. This research program consists of a careful theoretical study of few-body systems and methods for modeling these systems. During the past year several aspects of this program were completed. Brief summaries are given of work on the following topics: The relativistic three quark problem; the relativistic Balian-Brezin method; spin in light front quantum mechanical models; proton-deutron scattering and reactions; point form relativistic quantum mechanics of constituents; solutions of quantum mechanical anharmonic oscillators; shift operators and the U(N) multiplicity problem
Configuration space Faddeev calculations. Progress report, January 1, 1988--December 31, 1988( )

4 editions published between 1989 and 1994 in English and held by 0 WorldCat member libraries worldwide

The detailed study of few-body systems provides one of the most effective means for studying nuclear physics at subnucleon distance scales. For few-body systems the model equations can be solved numerically with errors less than the experimental uncertainties. We have used such systems to investigate the size of relativistic effects, the role of meson-exchange currents, and the importance of quark degrees of freedom in the nucleus. Complete calculations for momentum-dependent potentials have been performed, and the properties of the three-body bound state for these potentials have been studied. Few-body calculations of the electromagnetic form factors of the deuteron and pion have been carried out using a front-form formulation of relativistic quantum mechanics. The decomposition of the operators transforming convariantly under the Poincare group into kinematical and dynamical parts has been studies. New ways for constructing interactions between particles, as well as interactions which lead to the production of particles, have been constructed in the context of a relativistic quantum mechanics. To compute scattering amplitudes in a nonperturbative way, classes of operators have been generated out of which the phase operator may be constructed. Finally, we have worked out procedures for computing Clebsch-Gordan and Racah coefficients on a computer, as well as giving procedures for dealing with the multiplicity problem
