Available in PDF, EPUB and Kindle. Book excerpt: Angular distribution studies based on the low latitude Pioneer 10 data and a confirmatory analysis of Pioneer 11 data show that there exists a region in the near equatorial Jovian magnetosphere within which energetic electrons form strongly field aligned and bisymmetric pitch angle distributions ('dumbbell' distributions). This region encompasses the transition zone between the dipolar inner magnetosphere and the highly distended magnetodisc. The angular distributions of energetic protons in this same region are approximately isotropic. The existence of a significant asymmetry in the field aligned component of the particle distributions in the high latitude regions of this L-space is discussed.

Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 118. The magnetosphere is an open system that interacts with the solar wind. In this system, solar wind energy continuously permeates different regions of the magnetosphere through electromagnetic processes, which we can well describe in terms of current systems. In fact, our ability to use various methods to study magnetospheric current systems has recently prompted significant progress in our understanding of the phenomenon. Unprecedented coverage of satellite and ground?]based observations has advanced global approaches to magnetospheric current systems, whereas advanced measurements of electromagnetic fields and particles have brought new insights about micro?]processes. Increased computer capabilities have enabled us to simulate the dynamics not only of the terrestrial magnetosphere but also the magnetospheres of other planets. Based on such developments, the present volume revisits outstanding issues about magnetospheric current systems.
Download or read book Energetic Electrons in the Jovian Magnetosphere written by D. N. Baker and published by . This book was released on 1975 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Detailed analysis of the University of Iowa Pioneer 10 data using several design features of the instrument to accomplish particle species identification shows that the observed counting rates within the magnetosphere of Jupiter were caused primarily by electrons, E sub e> 0.06 MeV. This identification holds for the magnetodisc region (r approximately = or (R sub j), Jovian radii) as well as for the central magnetosphere (r approximately = or (R sub j)), as reported previously by Van Allen et al. (1974). Absolute omnidirectional intensities of electrons in the magnetodisc are presented for five integral energy ranges: E sub e 0.06, 0.55,> 5,> 21, and> 31 MeV.

Download or read book Plasma Sources of Solar System Magnetospheres written by Andrew F. Nagy and published by Springer. This book was released on 2016-01-27 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume reviews what we know of the corresponding plasma source for each intrinsically magnetized planet. Plasma sources fall essentially in three categories: the solar wind, the ionosphere (both prevalent on Earth), and the satellite-related sources. Throughout the text, the case of each planet is described, including the characteristics, chemical composition and intensity of each source. The authors also describe how the plasma generated at the source regions is transported to populate the magnetosphere, and how it is later lost. To summarize, the dominant sources are found to be the solar wind and sputtered surface ions at Mercury, the solar wind and ionosphere at Earth (the relative importance of the two being discussed in a specific introductory chapter), Io at Jupiter and – a big surprise of the Cassini findings – Enceladus at Saturn. The situation for Uranus and Neptune, which were investigated by only one fly-by each, is still open and requires further studies and exploration. In the final chapter, the book offers a summary of the little we know of Uranus and Neptune, then summarizes in a comparative way what we know of plasma sources throughout the solar system, and proposes directions for future research.

Download or read book Energetic Particles in the Heliosphere written by George M. Simnett and published by Springer. This book was released on 2016-12-01 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph traces the development of our understanding of how and where energetic particles are accelerated in the heliosphere and how they may reach the Earth. Detailed data sets are presented which address these topics. The bulk of the observations are from spacecraft in or near the ecliptic plane. It is timely to present this subject now that Voyager-1 has entered the true interstellar medium. Since it seems unlikely that there will be a follow-on to the Voyager programme any time soon, the data we already have regarding the outer heliosphere are not going to be enhanced for at least 40 years.

Download or read book On the Plasma Sheet in Jupiter s Dawn Magnetodisc written by James Alfred Van Allen and published by . This book was released on 1978 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: A detailed re-examination was made of the University of Iowa data on energetic electrons during a Pioneer 10 encounter with the plasma sheet in Jupiter's dawn magnetodisc at about 51 R sub J (Jupiter equatorial radii) on 6-7 December 1973. Repeated, also, was the analysis of data on energetic protons for this encounter. On the whole, it appears reasonable to accept the conclusion that very hot plasma (characteristic particle energy about 0.1 MeV) is an important and probably dominant contributor to the pressure of the plasma confined by the magnetic field in Jupiter's dawn magnetodisc. The pressure of energetic protons is greater than that of energetic electrons by a factor of the order of ten. It is plausible that charge neutrality exists for the energetic particles at a number density n of about .003/cu.cm. The additional presence of cool plasma is not excluded by present knowledge but an upper limit on its density can be placed on the basis of the relative un-importance of centrifugal pressure.
Download or read book On the Distributions of Low energy Protons and Electrons in the Earth s Magnetosphere written by Louis A. Frank and published by . This book was released on 1967 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent observations of low-energy proton and electron intensities over the energy range of about 100 eV to 50,000 eV in the local evening-midnight quadrant of the magnetosphere near the geomagnetic equatorial plane at 5 to 15 RE (RE, earth radii) geocentric radial distances are summarized with several comments concerning the relationship of these distributions of low-energy charged particles with earlier measurements. Of particular interest are the morphology of the distributions of low-energy protons of the extraterrestrial ring current during magnetic storms, the temporal variations of low-energy electron spectrums in the outer radiation zone and several salient features of the distributions of low-energy electrons in the vicinity of the 'trapping boundary' in the dark hemisphere of the earth's magnetosphere at about 8 RE geocentric distance near the magnetic equator.

Download or read book Several Observations of Low energy Protons and Electrons in the Earth s Magnetosphere with Ogo 3 written by Louis A. Frank and published by . This book was released on 1966 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: An initial survey is made of low-energy electrons and protons over geocentric radial distances ranging from 3 RE to 15 RE (RE, earth radius) with measurements obtained with a sensitive electrostatic analyzer device borne on the earth-satellite OGO 3. It is intended to provide an introduction to several of the characteristics of the spatial distributions of electrons and protons over an energy range 200 eV to 50 keV within the earth's magnetosphere near the magnetic equatorial plane. Several features of the charged particle distributions at the boundary of durable trapping of charged particles by the geomagnetic field at geocentric radial distances approximately 8 RE in the evening sector of the earth's magnetosphere are clarified. Simultaneous observations of the differential energy spectrums of electrons and protons, separately, over the aforementioned energy range are presented for regions in the earth's magnetic tail and deep within the radiation zones and will be important in delineating prominent acceleration mechanisms providing 'local' acceleration of charged particles within the earth's magnetosphere and its environs.
Download or read book The Magnetospheres of the Earth and Jupiter written by V. Formisano and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Symposium 'The Magnetospheres of the Earth and Jupiter' (May 28th-June 1st, 1974 in Frascati) was organized by the 'Laboratorio Plasma Spazio' of the CNR, on the occasion of its moving to the Frascati area. The main theoretical topic was to be covered by N. Brice, but he died on January 31st, in a plane crash at Pago Pago (Samoa). It seemed appropriate to all of us to honor Neil Brice by renaming the meeting: 'Neil Brice Memorial Symposium'. The Symposium covered problems of magnetospheric dynamics, of both the Earth and Jupiter, with emphasis on the comparison between the two objects. The collaboration of American scientists participating in the recent NASA plan etary missions has made it possible to have new important scientific results presented to and discussed by the scientific community. Of the many people who helped to make the meeting such a success, very special thanks goes to Prof. C. Kennel ofU.C.L.A. whose contribution to the organization of this symposium has been extremely important.
