Saturn from Cassini-Huygens by M Dougherty( Book )

7 editions published in 2009 in English and held by 76 WorldCat member libraries worldwide

This book reviews our current knowledge of Saturn featuring the latest results obtained by the Cassini-Huygens mission. A global author team addresses the planet{u2019}s origin and evolution, internal structure, composition and chemistry, the atmosphere and ionosphere, the magnetosphere, as well as its ring system. Furthermore, Saturn's icy satellites are discussed. The book closes with an outlook beyond the Cassini-Huygens mission. Colorfully illustrated, this book will serve as a reference to researchers as well as an introduction for students
Solar particle observations inside the magnetosphere during the 7 July 1966 event by S. M Krimigis( Book )

3 editions published in 1967 in English and held by 4 WorldCat member libraries worldwide

Observations of protons emitted by the 7 July 1966 solar flare at N34, W47 with the low-altitude--high-latitude University of Iowa satellite Injun IV show the following. (a) High energy (Ep about 27 MeV) protons arrive promptly over the earth's polar caps and decay in a manner consistent with diffusive propagation. (b) The counting rate due to protons in the interval 0.52 = or <Ep = or <4 MeV and moving normal to the magnetic vector shows a double plateau as the satellite moves over the polar caps. (c) The position of the 'knee' for protons in the above energy interval varies from L about 7.5 to L about 6.3 at magnetic local times of about 4.5 hours and about 11.5 hours, respectively. (d) After the sudden commencement the latitude gap between trapped protons and solar protons disappears, suggesting that some solar protons may become trapped in the earth's radiation belts. (e) Simultaneous observations with similar detectors inside the magnetosphere (Injun IV) and outside the magnetosphere (Explorer 33) show that low energy (about 0.5 MeV) protons have essentially immediate acess from the interplanetary space to the polar caps of the earth. Finally, the theoretical implications of these results are discussed. (Author)
Observations of low energy (~ 0.5 MeV) trapped protons with Injun IV by S. M Krimigis( Book )

3 editions published in 1967 in English and held by 4 WorldCat member libraries worldwide

Since the discovery of the low energy (of about 0.5 MeV) protons trapped in the geomagnetic field, several measurements have been reported on the intensities, angular distributions, energy spectra, and time variations of such protons. The present investigation extends the measurements to high latitudes (about 80 degrees) and low L values (L approximately = or> 1.1) with data obtained from the University of Iowa polar-orbiting Injun IV satellite. Constant intensity contours in absolute value of B - L space are presented for protons in the energy intervals 0.52 = or <Ep = or <4 MeV and 0.90 = or <Ep = or <1.8 MeV. The energy spectrum parameter Eo is computed as a function of L and it is shown that a major departure from the Eo proportional to 1/L cubed law is found for L approximately = or <3.5 at absolute value of B = 0.19 gauss. Data are presented on the redistribution of protons in the radiation zones following the 17 April 1965 magnetic storm
Simultaneous observations of solar protons inside and outside the magnetosphere by S. M Krimigis( Book )

2 editions published in 1967 in English and held by 4 WorldCat member libraries worldwide

Simultaneous observations of low energy (Approx. 0.5 MeV) protons emitted in the solar flare of 7 July 1966 were made with University of Iowa detectors on board the earth satellites Explorer 33 and Injun IV, located outside and inside the earth's magnetosphere, respectively. It was found that such protons have full and essentially immediate access from interplanetary space to the polar caps of the earth. (Author)
An interplanetary diffusion model for the time behavior of intensity in a solar cosmic ray event by S. M Krimigis( Book )

3 editions published in 1965 in English and held by 3 WorldCat member libraries worldwide

It is found possible to give a coherent interpretation of the time history of the intensity of several solar cosmic ray events in terms of a unified interplanetary diffusion model which assumes that the diffusion coeffieient D = M r to the B power, where r is the heliocentric radial distance and M and B are parameters, which may be dependent on particle energy E. The model is particularly successful in accounting for the decay phases. For the September 28, 1961 event M varies as E to the 0.33 power and, assuming spherical geometry, B is equal to one for 55 <E <500 MeV and decreases rapidly at lower energies. At r = 1 A.U. the mean free path lambda is about 0.081 A.U. for E = 200 MeV and 0.15 for E = 23 MeV. The energy dependences of B and lambda suggest 0.006 A.U. as the order of magnitude of the scale size of irregularities in the interplanetary magnetic field. The source spectrum is inferred. The possibility of non-spherical geometry of diffusion is considered, as is the implication of the results with respect to the solar modulation of galactic cosmic radiation. (Author)

Observations of the solar particle event of 5 to 12 february 1965 with mariner iv and injun iv by S. M Krimigis( Book )

2 editions published in 1967 in English and held by 2 WorldCat member libraries worldwide

The solar cosmic ray event of 5-12 February 1965 is the most intense one of a ten month period of interplanetary observation (28 November 1964 - 30 September 1965) with Mariner 4 during the recent epoch of minimum solar activity. A full time history of the intensities of energetic particles is presented from onset at 1835 + or - 10 U.T. on 5 February following a 2(+) solar flare N08, W25 (which began at 1750 U.T.) until disappearance into the background near the end of 12 February. A mixture of low energy protons E sub p> 0.5 MeV and electrons E sub e> keV is identified in this event for the first time
GEOMAGNETICALLY TRAPPED ALPHA PARTICLES by S. M Krimigis( Book )

2 editions published in 1967 in English and held by 2 WorldCat member libraries worldwide

This paper reports results of an extensive search for geomagnetically trapped nuclei heavier than deuterons in the energy range 0.52 <or = E <or = 4 MeV/nucleon, an energy region which is roughly two orders of magnitude below the regions previously investigated. The presence of geomagnetically trapped alpha particles was established. The significance of these observations lies in the fact that, although the intensity and energy spectrum of trapped protons E sub p approximately equal or> 30 MeV can be reasonably accounted for on the basis of the cosmic ray albedo neutron hypothesis, protons of energy below 30 MeV and down to 0.1 MeV or less cannot possibly be attributed to the albedo-neutron source. Thus, the special motivation for study of trapped nuclei having Z> or = 2 is to provide a set of parameters on one or more 'tracer' components of the radiation belts for testing the validity of hypotheses on their origin and on the origin of the much more abundant proton component
Observed absence of energetic electrons and protons near Venus by James A Van Allen( Book )

2 editions published in 1967 in English and held by 2 WorldCat member libraries worldwide

The report discusses the following points: (a) The environment of Venus is almost, if not completely, devoid of energetic particles associated with the planet, as is the environment of Mars and that of the moon. (b) On the basis of physical similitude with observational and theoretical knowledge of the earth's magnetosphere, we conclude that the intrinsic magnetic dipole moment of Venus is certainly less than 0.01 and probably less than 0.001 of that of the earth. Corresponding upper limits on the equatorial surface magnetic field of Venus are about 350 and 35 x 10 to the -5th power gauss, respectively. (c) The magneto-fluid dynamical interaction of the solar wind with the conducting ionosphere and/or the body of Venus is too weak to generate an observable intensity of electrons having energies exceeding 45 keV

Invited Papers Vol. 12 by Louis Leprince-Ringuet( )

1 edition published in 1969 in English and held by 0 WorldCat member libraries worldwide

The Proceedings of the 17th International Cosmic Ray Conference held in Paris, July 15 to 25, 1981, appear in two sets. The Regular Volumes, 1 to 8, contain contributed papers received at the Secretariat by April 1st, 1981. They were issued at the opening of the Conference. The Late Volumes, 9 to 14, contain contributed papers received after that date, Invited and Rapporteur Talks, and the General Index. The assiduous reader will notice several changes with respect to the well-established traditions of the Conference. 1/ Following a recommendation of the Commission an Cosmic Rays of IUPAP, and although an increase in the total number of papers submitted was noticed as compared to the 16th ICRC (Kyoto, 1979), the total number of pages has been significantly reduced, thanks to introduction of three new rules for publication. (i) None of the first "Preliminary" Abstracts was published. These abstracts had to be confirmed, either by a new "Confirming Abstract" or by a Full Paper. The Confirming Abstracts are included in the Proceedings. (ii) The sum of the "fractional" contributions of each author should not exceed 3 papers, and each author should not appear in more than 10 papers. (iii) The maximum number of pages per paper was reduced from 6 to 4. The Organizing Committee thanks all authors who have, in their vast majority, very efficiently cooperated by kindly complying with these new rules. The papers we selected an the basis of the Preliminary Abstracts
