Solar Neutrons and Related Phenomena by Lev Dorman Pdf

Short Historical Overview In the 1940s, two phenomena in the ?eld of cosmic rays (CR) forced scientists to think that the Sun is a powerful source of high-energy particles. One of these was discovered because of the daily solar variation of CR, which the maximum number of CR observed near noon (referring to the existence of continuous ?ux of CR from the direction of the Sun); this became the experimental basis of the theory that CR’s ́ originate from the Sun (or, for that matter, from within the solar system) (Alfven 1954). The second phenomenon was discovered when large ?uxes of high energy particles were detected from several solar ?ares, or solar CR. These are the - called ground level events (GLE), and were ?rst observed by ionization chambers shielded by 10 cm Pb (and detected mainly from the secondary muon-component CR that they caused) during the events of the 28th of February 1942, the 7th of March 1942, the 25th of July 1946, and the 19th of November 1949. The biggest such event was detected on the 23rd of February 1956 (see the detailed description in Chapters X and XI of Dorman, M1957). The ?rst phenomenon was investigated in detail in Dorman (M1957), by ?rst correcting experimental data on muon temperature effects and then by using coupling functions to determine the change in particle energy caused by the solar-diurnal CR variation.

Energetic Phenomena on the Sun by M. R. Kundu,B. Woodgate,E.J. Schmahl Pdf

This publication is a result of three meetings, each 5 days long, held at the Goddard Space Flight Center on January 24-28, 1983, June 8-14, 1983, and February 13-17, 1984. The meetings were held in the interim between the full operations of the Solar Maximum Mission (SMM) in 1980, and the renewed operations after its repair in orbit in April 1984. Their general objectives were as follows: o Synthesize flare studies after three years of SMM data analysis. Many analyses of individual flares and individual phenomena, often jointly across many data sources had been published, but a need existed for a broader synthesis and updating of our understanding of solar flares since the Skylab Flare Workshops held several years earlier. o Encourage a broader participation in the SMM data anlysis and combine this more fully with theory and other data sources--data obtained with other spacecraft such as the HINOTORI, P78-1, and ISEE-3 spacecrafts, and with the Very Large Array (VLA) and many other ground-based instruments. Many coordinated data sets, unprecedented in their breadth of coverage and multiplicity of sources, had been obtained within the structure of the Solar Maximum Year (SMY). o Stimulate joint studies, and publication in the general scientific literature. The intended primary benefit was for informal collaborations to be started or broadened at the Workshops with subsequent publications. o Provide a special publication resulting from this Workshop. o Provide a starting point of understanding for planning renewed full observations with the repaired SMM.

Acoustic, Electromagnetic, Neutron Emissions from Fracture and Earthquakes by Alberto Carpinteri,Giuseppe Lacidogna,Amedeo Manuello Pdf

This book presents the relevant consequences of recently discovered and interdisciplinary phenomena, triggered by local mechanical instabilities. In particular, it looks at emissions from nano-scale mechanical instabilities such as fracture, turbulence, buckling and cavitation, focussing on vibrations at the TeraHertz frequency and Piezonuclear reactions. Future applications for this work could include earthquake precursors, climate change, energy production and cellular biology. A series of fracture experiments on natural rocks demonstrates that the TeraHertz vibrations are able to induce fission reactions on medium weight elements accompanied by neutron emissions. The same phenomenon appears to have occurred in several different situations, particularly in the chemical evolution of the Earth and Solar System, through seismicity (rocky planets) and storms (gaseous planets). As the authors explore, these phenomena can also explain puzzles related to the history of our planet, like the ocean formation or the primordial carbon pollution, as well as scientific mysteries, like the so-called “cold nuclear fusion” or the correct radio-carbon dating of organic materials, such as the Turin Shroud. In biology, Piezonuclear reactions could explain the mechanism that governs the so-called "sodium-potassium pump" and more in general, the metabolic processes. Scientists engaged in seismology, geophysics, geochemistry, climatology, planetology, condensed matter physics and b iology, as well as those involved in theoretical and applied mechanics, will all appreciate the innovative work presented here in a holistic way.

The Origin of the Chemical Elements and the Oklo Phenomenon by P.K. Kuroda Pdf

At about the time I was a student in the 1930's, it had become increasingly evident that all the elements existing on the Earth today had already been discovered. Scientists then began "discovering" new elements by means of their artificial synthesis and some of the man-made elements found important military as well as industrial applications. I have often wondered, however, if the importance of these artificial elements may not have been overly emphasized by contemporary scientists for their practical applications. It seemed to me that these man-made elements were destined to play an important role du ring the second half of the 20th century in the study of the origin of the elements in the Universe. This subject of study, which dates back to the days of ancient Greek philoso phers, may be regarded as the most fundamental in the entire compass of our modetn science. Since I joined the faculty of the University of Arkansas in the early 1950's, I have had the good fortune of being able to maintain a long-range research project, the ultimate goal of which was to elucidate the origin of the elements. I have presented the results from these and related investigations on numerous occasions. While serving as a tour speaker of the American Chemical Society for many years, I have had the privilege of visiting many ofthe local sections to present a lecture on the origin ofthe elements.

Progress in Neutron Star Research by Andrew P. Wass Pdf

Neutron stars are the collapsed cores of some massive stars. They pack roughly the mass of our Sun into a region the size of a city. Neutron stars are believed to form in supernovae such as the one that formed the Crab Nebula. The stars that eventually become neutron stars are thought to start out with about 15 to 30 times the mass of our sun. It appears that for initial masses much less than 15 solar masses the star becomes a white dwarf, whereas for initial masses a lot higher than 30 solar masses a black hole results instead. It is estimated that there are 108 neutron stars in our galaxy. About 1000 of these have actually been observed by astronomers so far. This new book presents recent and important research results in the field.

Energy Conversion and Particle Acceleration in the Solar Corona by Karl-Ludwig Klein Pdf

The conversion of energy generated in the Sun's interior creates its hot corona and a wealth of dynamical phenomena such as flares and mass ejections. Based on recent significant progress in understanding magnetic reconnection and a wealth of new observations of energetic particle signatures from the sun, the present volume reviews the current theoretical and experimental status in the field. Paying attention to both the details and the broader picture, this book addresses both the experienced researcher as well as non-specialist researchers from related areas and postgraduate students.

Physics of Neutron Star Interiors by D. Blaschke,N.K. Glendenning,A. Sedrakian Pdf

Neutron stars are the densest observable bodies in our universe. Born during the gravitational collapse of luminous stars - a birth heralded by spectacular supernova explosions - they open a window on a world where the state of the matter and the strengths of the fields are anything but ordinary. This book is a collection of pedagogical lectures on the theory of neutron stars, and especially their interiors, at the forefront of current research. It addresses graduate students and researchers alike, and should be particularly suitable as a text bridging the gap between standard textbook material and the research literature.
