Download or read book Energetic Charged Particle Interactions with Atmospheres and Surfaces written by Robert E. Johnson and published by Springer Science & Business Media. This book was released on 2013-03-13 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: On attending a conference on the Jovian satellites at UCLA, I heard Lou Lanze rotti vigorously present the exciting data on the sputtering of water ice by Me V protons taken with W. L. Brown at AT&T Bell Labs. In his inimitable way he made clear that this new electronic sputtering process was very poorly under stood and was very important for surface properties of sattelites. I was immedia tely hooked, and have been working ever since with Lanzerotti, Brown, my col league at Virginia, John Boring, and Bo Sundqvist at Uppsala on understanding the ejection of material from surfaces and applying laboratory results to intere sting planetary problems. In the course of writing this book I also had the benefit of spending a semester with the Planetary Geosciences group in Hawaii, thanks to Tom McCord, a period of time with Doug Nash at JPL, and a period ot time with the group at Catania. The book was started with the encouragement of Lou Lanzerotti. The writing has gone slowly as the field has been changing rapidly. Even now I feel it is incom plete, as the interesting Halley dust data have just recently been interpreted in detail, Voyager has recently visited Neptune, and the data on Pluto are rapidly improving. However, most of the principles for plasma ion alteration of surfaces and gases have been established allowing, I hope, a coherent and useful frame work for incorporating both new laboratory and planetary data.
Download or read book An Introduction to the Passage of Energetic Particles through Matter written by N.J Carron and published by CRC Press. This book was released on 2006-11-10 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Identifying where to access data, extracting a needed subset from available resources, and knowing how to interpret the format in which data are presented can be time-consuming tasks for scientists and engineers. By collecting all of this information and providing a background in physics, An Introduction to the Passage of Energetic Particles through Matter enables specialists and nonspecialists alike to understand and apply the data. Making modern data more accessible, this book explores the interactions with matter of energetic particles, including photons, electrons, protons, alpha particles, and neutrons. It presents quantities of interest in many applications, such as photon and neutron cross sections, charged particle stopping powers, electron mean ranges, and angular distributions. The book also discusses electron multiple scattering and models for electron mean range against both stopping power and scattering. The author uses numerous graphs throughout the book to illustrate the material and describes the basic physics underlying all processes. The accompanying CD-ROM includes full datasets and large color contour graphs of cross sections, stopping powers, and ranges in all elements at all interesting energies. Compiling information that is scattered throughout the literature, An Introduction to the Passage of Energetic Particles through Matter provides a comprehensive foundation of particle interactions that is of prime importance to many areas of applied physics and supplies an introduction to the massive, invaluable Evaluated Nuclear Data File (ENDF) library.
Download or read book Solar Energetic Particles written by Donald V. Reames and published by Springer. This book was released on 2017-03-10 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: This concise primer introduces the non-specialist reader to the physics of solar energetic particles (SEP) and systematically reviews the evidence for the two main mechanisms which lead to the so-called impulsive and gradual SEP events. More specifically, the timing of the onsets, the longitude distributions, the high-energy spectral shapes, the correlations with other solar phenomena (e.g. coronal mass ejections), as well as the all-important elemental and isotopic abundances of SEPs are investigated. Impulsive SEP events are related to magnetic reconnection in solar flares and jets. The concept of shock acceleration by scattering on self-amplified Alfvén waves is introduced, as is the evidence of reacceleration of impulsive-SEP material in the seed population accessed by the shocks in gradual events. The text then develops processes of transport of ions out to an observer. Finally, a new technique to determine the source plasma temperature in both impulsive and gradual events is demonstrated. Last but not least the role of SEP events as a radiation hazard in space is mentioned and a short discussion of the nature of the main particle telescope designs that have contributed to most of the SEP measurements is given.

Download or read book The Atmosphere and Climate of Mars written by Robert M. Haberle and published by Cambridge University Press. This book was released on 2017-06-29 with total page 613 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humanity has long been fascinated by the planet Mars. Was its climate ever conducive to life? What is the atmosphere like today and why did it change so dramatically over time? Eleven spacecraft have successfully flown to Mars since the Viking mission of the 1970s and early 1980s. These orbiters, landers and rovers have generated vast amounts of data that now span a Martian decade (roughly eighteen years). This new volume brings together the many new ideas about the atmosphere and climate system that have emerged, including the complex interplay of the volatile and dust cycles, the atmosphere-surface interactions that connect them over time, and the diversity of the planet's environment and its complex history. Including tutorials and explanations of complicated ideas, students, researchers and non-specialists alike are able to use this resource to gain a thorough and up-to-date understanding of this most Earth-like of planetary neighbours.

Download or read book New View of the Moon 2 written by Clive R Neal and published by Walter de Gruyter GmbH & Co KG. This book was released on 2024-05-06 with total page 890 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much has happened in the world in the 17 years since the first New Views of the Moon was published as volume 60 of the Mineralogical Society of America in 2006. An exciting new era of lunar exploration has begun, including the promise of resuming human lunar exploration, exploring the lunar Poles, and missions to many other high-priority science targets. It is fitting, therefore, to now summarize the current state of knowledge to the degree possible at a time when advancements in knowledge of the Moon are proceeding at a breakneck pace. Therefore, during this period of unprecedented lunar exploration activity, and as we continue to rebound from a global pandemic, we now happily announce this New Views of the Moon 2 volume summarizing the advances in lunar science and exploration since 2006. The Steering Committee is eternally grateful to all contributors and especially the chapter leads, and to Professor Makiko Ohtake (University of Aizu, Japan) and Dr. David Blewett (Johns Hopkins University Applied Physics Laboratory, U.S.A.) for organizing the New Views of the Moon 2 Electronic Annex. We deeply appreciate the hard work and dedication of everyone involved in the production of this volume, especially Rachel Russell and Ian Swainson at the Mineralogical Society of America. This volume helps to frame our knowledge and expectations for an exciting future of lunar science and exploration and the new discoveries to be made. Having humans return to the Moon now seems more likely than it ever has since the last humans left the Moon on 14 December 1972.

Available in PDF, EPUB and Kindle. Book excerpt: Planetary Aeronomy is a modern and concise introduction to the underlying physical and chemical processes that govern the formation and evolution of the upper atmospheres of planets. The general approach employed permits consideration of the growing number of extrasolar planets, the detailed observation of which will become possible over the next decades. The book explains the physics behind many atmospheric processes, which are relevant for the evolution of planetary atmospheres and their water inventories, and also contains useful scaling laws and analytical expressions that can be applied to any planet. Readers thus gain insight into the evolution of terrestrial planets and their long-time habitability, atmospheric stability, etc. This volume can be used both as graduate textbook for students wishing to specialize in the field as well as succinct compendium for researchers in the field.
Download or read book Solar System Ices written by B. Schmitt and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 819 pages. Available in PDF, EPUB and Kindle. Book excerpt: Predicted long ago to be present on the surface of planetary bodies by theoreticians and recently shown by interplanetary spacecraft and ground- based instruments to be ubiquitous in the Solar System, ices in a broad sense have become an extremely important subject in planetary research. Ices found on objects formed in the remote parts of the Solar System contain a message about the composition and mode of formation of our planetary system. There are also objects that contain icy materials that bear signatures of past events on a geological timescale. Their study is one of the best means of inquiring about the origins, accessing the past and anticipating the future of our Solar System. The reviews in this book collect together a series of papers covering the physics and chemistry of ices, as well as the geology of icy surfaces. They present an extensive summary of their chemical and physical properties relevant to planetary astronomy. They also provide an overview of planetary bodies that contain ices and the outstanding problems of the field. Audience: The book is intended to become a reference for researchers and graduate students. It is accessible to senior graduate students with a background in planetary science.
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 Origin and Evolution of Planetary Atmospheres written by Helmut Lammer and published by Springer Science & Business Media. This book was released on 2012-09-13 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the author’s own work and results obtained by international teams he coordinated, this SpringerBrief offers a concise discussion of the origin and early evolution of atmospheres of terrestrial planets during the active phase of their host stars, as well as of the environmental conditions which are necessary in order for planets like the Earth to obtain N_2-rich atmospheres. Possible thermal and non-thermal atmospheric escape processes are discussed in a comparative way between the planets in the Solar System and exoplanets. Lastly, a hypothesis for how to test and study the discussed atmosphere evolution theories using future UV transit observations of terrestrial exoplanets within the orbits of dwarf stars is presented.
Download or read book Binding Energy and Effectiveness Mass of Charged Particles Trapped on Surfaces written by Oscar Hipolito and published by . This book was released on 1977 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interaction of a charged particle with the surface excitations of a semi-infinite medium is discussed. Only the case where the particle is outside the material and trapped near the surface by its image potential was considered. By the use of a cononical transformation which exhibits the bound states due to the image charge in the non-perturbed transformed Hamiltonian, the binding energy and the effective mass of a charged particle are determined for motion parallel to the surface. For the highest perpendicular sub-bands the corrections to the energy and mass of the particle are negligible. Applying the method to determine the binding energy of the ground-state of an electron trapped near the LiF surface, one finds the value E(0) = -0.25 eV.
Download or read book The Cassini Huygens Mission written by C.T. Russell and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 641 pages. Available in PDF, EPUB and Kindle. Book excerpt: The exploration of the planets is the modem counterpart to the exploration voy ages of old. To reach the new world Columbus had to secure funding from Queen Isabella, outfit his three ships and set sail on a long journey. To explore the Amer ican Pacific Northwest, Lewis and Clark had a similar task of obtaining funding, purchasing equipment and going to points unknown, even though their path was across land and not sea. Today our journey is through space, rather than across land or sea, but we still travel with ships, now spaceworthy craft, rather than seaworthy. Our spacecraft are smaller than the ships of yore, crammed with electronics rather than provisions because man cannot go along on these journeys. We now rely on robots to be our eyes and ears at these distant worlds. Nevertheless, some aspects of exploration have not changed over the centuries. People are still fascinated by these unknown worlds and desire to explore them, and the process of obtaining the large sums of public moneys to finance these journeys still requires much pleading with authorities.
Download or read book Kappa Distributions written by George Livadiotis and published by Elsevier. This book was released on 2017-04-19 with total page 738 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kappa Distributions: Theory and Applications in Plasmas presents the theoretical developments of kappa distributions, their applications in plasmas, and how they affect the underpinnings of our understanding of space and plasma physics, astrophysics, and statistical mechanics/thermodynamics. Separated into three major parts, the book covers theoretical methods, analytical methods in plasmas, and applications in space plasmas. The first part of the book focuses on basic aspects of the statistical theory of kappa distributions, beginning with their connection to the solid backgrounds of non-extensive statistical mechanics. The book then moves on to plasma physics, and is devoted to analytical methods related to kappa distributions on various basic plasma topics, spanning linear/nonlinear plasma waves, solitons, shockwaves, and dusty plasmas. The final part of the book deals with applications in space plasmas, focusing on applications of theoretical and analytical developments in space plasmas from the heliosphere and beyond, in other astrophysical plasmas. Kappa Distributions is ideal for space, plasma, and statistical physicists; geophysicists, especially of the upper atmosphere; Earth and planetary scientists; and astrophysicists. Answers important questions, such as how plasma waves are affected by kappa distributions and how solar wind, magnetospheres, and other geophysical, space, and astrophysical plasmas can be modeled using kappa distributions Presents the features of kappa distributions in the context of plasmas, including how kappa indices, temperatures, and densities vary among the species populations in different plasmas Provides readers with the information they need to decide which specific formula of kappa distribution should be used for a certain occasion and system (toolbox)
