Download or read book Astronomy and Astrophysics Abstracts written by S. Böhme and published by Springer Science & Business Media. This book was released on 2013-12-14 with total page 787 pages. Available in PDF, EPUB and Kindle. Book excerpt: Astronomy and Astrophysics Abstracts, which has appeared in semi-annual volumes since 1969, is devoted to the recording, summarizing and indexing of astronomical publications throughout the world. It is prepared under the auspices of the International Astronomical Union (according to a resolution adopted at the 14th General Assembly in 1970). Astronomy and Astrophysics Abstracts aims to present a comprehensive documenta tion of literature in all fields of astronomy and astrophysics. Every effort will be made to ensure that the average time interval between the date of receipt of the original literature and publication of the abstracts will not exceed eight months. This time interval is near to that achieved by monthly abstracting journals, compared to which our system of accumu lating abstracts for about six months offers the advantage of greater convenience for the user. Volume 31 contains literature published in 1982 and received before July 15, 1982; some older literature which was received late and which is not recorded in earlier volumes is also included. We acknowledge with thanks contributions to this volume by Dr. J. Bouska, Prague, who surveyed journals and publications in Czech and supplied us with abstracts in English .
Book Synopsis Spectroscopy of Astrophysical Plasmas by : A. Dalgarno
Download or read book Spectroscopy of Astrophysical Plasmas written by A. Dalgarno and published by Cambridge University Press. This book was released on 1987-06-11 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: A group of acknowledged experts describe the use of spectroscopy as a diagnostic probe of astronomical environments. The broad sweep of the book enables good coverage to be given to all the situations in which plasmas are encounteres in astronomical investigations. Specifically, the articles include quasars, Seyfert galaxies, active galactic nuclei, the solar chromosphere and corona, galactic HII regions, circumstellar shells, interstellar gas, supernova remnants and interstellar clouds. The book includes an account of the basic aspects of spectroscopy in a chapter on laboratory astrophysics. The book was stimulated by the extraordinary contributions to astronomical spectroscopy of Leo Goldberg, and is dedicated to him. Throughout, this book is written with the needs of students in astronomy and astrophysics in mind. Each chapter includes a summary or conclusions about the future direction of research. Furthermore there are extensive bibliographies. This textbook is therefore an excellent introduction to research in astrophysics and it will act as a pathfinder to the primary literature.
Book Synopsis Spectral Line Broadening by Plasmas by : Hans Griem
Download or read book Spectral Line Broadening by Plasmas written by Hans Griem and published by Elsevier. This book was released on 2012-12-02 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spectral Line Broadening by Plasmas deals with spectral line broadening by plasmas and covers topics ranging from quasi-static approximation and impact approximation to intermediate approximations and correlation effects. Experimental results for hydrogen lines, lines with forbidden components, and ionized helium lines are presented. Applications such as density and temperature measurements are also considered. Comprised of four chapters, this volume begins with an overview of the effects of electric fields from electrons and ions (both acting as point charges) on spectral line shapes. The next chapter surveys theoretical work, paying particular attention to quasi-static, impact, and intermediate approximations as well as correlation effects. Stark broadening experiments are then discussed, with special emphasis on experiments capable of checking the accuracy or validity limits of the various approximations. The final chapter is devoted to applications in laboratory plasma physics and astronomy, focusing on density and temperature measurements and opacity calculations as well as the analysis of stellar atmospheres, amplitudes and spectra of plasma waves, and radio frequency lines. This book should appeal to students, practitioners, and researchers in pure and applied physics.

Book Synopsis Spectral Line Shapes in Astrophysics and Related Topics by : Milan S. Dimitrijević
Download or read book Spectral Line Shapes in Astrophysics and Related Topics written by Milan S. Dimitrijević and published by MDPI. This book was released on 2020-02-18 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spectral lines, widths, and shapes are powerful tools for emitting/absorbing gas diagnostics in different astrophysical objects (from the solar system to the most distant objects in the universe—quasars). On the other hand, experimental and theoretical investigations of laboratory plasma have been applied in spectroscopic astrophysical research, especially in research on atomic data needed for line shape calculations. Data on spectral lines and their profiles are also important for diagnostics, analysis, and the modelling of fusion plasma, laser-produced plasma, laser design and development, and various plasmas in industry and technology, like light sources based on plasmas or the welding and piercing of metals by laser-produced plasma. The papers from this book can be divided into four groups: 1. stark broadening data for astrophysical and laboratory plasma investigations; 2. applications of spectral lines for astrophysical and laboratory plasma research; 3. spectral line phenomena in extragalactic objects, and 4. laboratory astrophysics results for spectra investigation. The reviews and research papers, representing new research on the topics presented in this book, are of interest for specialists and PhD students. We hope that the present book will be useful and interesting for scientists interested in the investigation of spectral line shapes and will contribute to the education of young researchers and PhD students.

Book Synopsis Theory of Spectrochemical Excitation by : Paul W. Boumans
Download or read book Theory of Spectrochemical Excitation written by Paul W. Boumans and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are more things in heaven and earth, Horatio, Than are dreamt of in your philosophy. Hamlet There exists a fairly large number of textbooks concerned with spectrochemical analysis. Most of them deal with practical applications and instrumental factors, and provide the reader with the knowledge indispensable for conducting analyses with the help of emission spectra. Practical knowledge and experience are indeed important requisites for success fully exploiting the spectrochemical method in the field of analytical chemistry. As the method is essentially empirical, it is, in principle, a simple one, provided that we succeed in exciting all samples in an identical manner; for then, relative intensities of spectral lines can serve as the 'weights' by which to measure amounts of elements. However, creating the required constancy of excitation conditions is hampered by the very nature of the sample, whose composition profoundly influences the excitation characteristics of the light source. Therefore, spectrochemists are inevitably engaged in all the processes that determine the radiation output of the light source for a given sample. Dealing, with this ensemble of processes, that is, with 'excitation' in the widest sense, is the object of this book (cf. § 1. 1). The reader will seek in vain for enumerations of practical rules that would tell him how to tackle a particular analysis problem.

Book Synopsis Physics of Highly Excited Atoms and Ions by : Vladimir S. Lebedev
Download or read book Physics of Highly Excited Atoms and Ions written by Vladimir S. Lebedev and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph is devoted to the basic aspects of the physics of highly ex cited (Rydberg) states of atom's. After almost twenty years, this remains a hot topic of modern atomic physics. Such studies are important for many areas of physics and its applications including spectroscopy, astrophysics and radio astronomy, physics of electronic and atomic collisions, kinetics and di agnostics of gases, and low- and high-temperature plasmas. Physical phenom ena in radiative, collisional, and spectral-line broadening processes involving Rydberg atoms and ions are primarily determined by the peculiar properties and exotic features of highly excited states. The growth of interest and research activity in the physics of Rydberg the last two decades was stimulated by an extremely rapid de atoms over velopment of high-resolution laser spectroscopy, methods of selective excita tion and detection of highly excited states, atomic-beam techniques as well as radio astronomy. This has facilitated significant progress in the differ ent directions of the physics of highly excited atoms being of fundamental and practical importance. In particular, evident advances were achieved in studies of the structure and spectra of highly excited atoms, their behavior in static electric and magnetic fields, interactions with electromagnetic ra diation, spectral-line broadening and the shift of Rydberg series, collisions with electrons, ions, atoms, and molecules, etc. The principle objective of the present book is to reflect the most important physical approaches and efficient theoretical techniques in the modem physics of highly excited atoms and ions.
