English | ISBN: 9812560327 | 2004 | 260 pages | PDF | 5 MB
The r-process is a major mechanism for producing elements heavier than Fe. In this book, recent developments in theoretical, experimental and observational studies of the r-process are presented in 25 contributions. The collected papers are up to date, comprehensive and yet concise. The topics covered include experiments on nuclei far from stability, nuclear theory input for the r-process, observational and theoretical studies on abundances of heavy nuclei, and astrophysical models of the r-process.

Free Download Radiation in Astrophysical Plasmas By V. V. Zheleznyakov (auth.)
1996 | 462 Pages | ISBN: 9401065748 | PDF | 34 MB
Interest in the problem of interaction between radiation and astrophysical plasmas arose decades ago. Initially, this was closely related to the discovery of radio emission from the Sun and Galaxy which alerted theoretical radio astronomers to the problem of the origin of extra-terrestrial radio emission. It has been found that the observed radio emission from cosmic sources is generated by virtue of the mechanisms which work mainly in plasma (an ionized gas). Recently, the theory of generation and propagation of radiation in astrophysical plasmas has outgrown its parent domain of theoretical radio astronomy and is being successfully applied to other fields, such as high-energy astrophysics. General results obtained in this field may also help to better understand the complicated phenomena in laboratory plasmas on the Earth. At the same time, analysis of interaction between radiation and astrophysical plasmas under extreme conditions (strong magnetic fields of white dwarfs and neutron stars or strong gravitational fields in the vicinity of black holes) stimulates the development of plasma physics as a whole. In fact, the physics of plasma under extreme conditions in space is a new branch of fundamental science. The monograph contains the description of physical processes involved in interaction between radiation and astrophysical plasmas. It comprises the reasonable minimum necessary for understanding the emission and propagation of electromagnetic waves in astrophysical plasmas; without this minimum one could not succeed in interpreting the results of a number of astronomical observations. Audience: This monograph will be useful for graduate and post-graduate students and young scientists as a textbook on plasma astrophysics and the issues of plasma physics dealing with radiation. At the same time, the book can be used by specialists on astrophysics, radio astronomy and plasma physics.

Free Download Astrophysical and Laboratory Plasmas: A Festschrift for Professor Sir Robert Wilson By Allan J. Willis, Thomas W. Hartquist (auth.), A. J. Willis, T. W. Hartquist (eds.)
1996 | 400 Pages | ISBN: 9048147298 | PDF | 14 MB
Throughout his career Sir Robert Wilson has demonstrated that advances in a wide variety of fields in astrophysics and laboratory physics are achievable through the application of fundamental plasma spectroscopy. His work has included: optical studies that probed the nature of interstellar dust and first revealed the existence of O star winds; vacuum ultraviolet and X-ray diagnosis of fusion plasmas; rocket ultraviolet and X-ray observations of the Sun; and the conception, development and use of the International Ultraviolet Explorer (IUE) satellite which has contributed greatly to stellar, interstellar and extragalactic astrophysics. This volume contains reviews honouring Sir Robert and reflecting his interests.

Free Download Astrophysical Applications of Gravitational Lensing: Proceedings of the 173rd Symposium of the International Astronomical Union, Held in Melbourne, Australia, 9-14 JULY, 1995 By Hans-Walter Rix (auth.), C. S. Kochanek, J. N. Hewitt (eds.)
1996 | 443 Pages | ISBN: 079233955X | PDF | 13 MB
EDWIN TURNER AND RACHEL WEBSTER Co-Chairs, Scientific Organizing Committee lAU Symposium 173, Astrophysical Applications of Gravitational Lenses, was held in Melbourne, Australia from July 9-14, 1995. The Symposium was sponsored by lAU Commissions 47 and 40. With the discovery by Walsh and collaborators of the first instance of a gravitational lens, the multiply imaged quasar 0957+561, the area of grav itational lensing moved from speculative theory to a major astrophysical tool. Since that time, there have been regular, approximately biennial in ternational meetings both in Europe and in North America, which have specifically focussed on gravitational lensing. On this occasion, with the blessing of the lA U, the meeting was held at the University of Melbourne in Australia. It was the first international astronomical meeting to be held at the University of Melbourne, and hope fully has given the astronomical community some enthusiasm for trekking half-way round the globe to Australia to discuss their latest work.

Free Download Lyman-alpha as an Astrophysical and Cosmological Tool: Saas-Fee Advanced Course 46. Swiss Society for Astrophysics and Astronomy by Mark Dijkstra
English | EPUB | 2019 | 419 Pages | ISBN : 3662596229 | 96.5 MB
The hydrogen Lyman-alpha line is of utmost importance to many fields of astrophysics. This UV line being conveniently redshifted with distance to the visible and even near infrared wavelength ranges, it is observable from the ground, and provides the main observational window on the formation and evolution of high redshift galaxies. Absorbing systems that would otherwise go unnoticed are revealed through the Lyman-alpha forest, Lyman-limit, and damped Lyman-alpha systems, tracing the distribution of baryonic matter on large scales, and its chemical enrichment.

This new, fourth, edition of Allen’s classic Astrophysical Quantities belongs on every astronomer’s bookshelf. It has been thoroughly revised and brought up to date by a team of more than ninety internationally renowned astronomers and astrophysicists. While it follows the basic format of the original, this indispensable reference has grown to more than twice the size of the earlier editions to accommodate the great strides made in astronomy and astrophysics. It includes detailed tables of the most recent data on: – General constants and units – Atoms, molecules, and spectra – Observational astronomy at all wavelengths from radio to gamma-rays, and neutrinos – Planetary astronomy: Earth, planets and satellites, and solar system small bodies – The Sun, normal stars, and stars with special characteristics – Stellar populations – Cataclysmic and symbiotic variables, supernovae – Theoretical stellar evolution – Circumstellar and interstellar material – Star clusters, galaxies, quasars, and active galactic nuclei – Clusters and groups of galaxies – Cosmology. As well as much explanatory material and extensive and up-to-date bibliographies.

Wherever possible, the original source of the material being pre sented is referenced, together with references to more recent modifications and applications. More accessible reprints and translations of the early papers are also referenced. In this way the reader is provided with the often ignored his torical context together with an orientation to the more recent literature. Any omission of a reference is, of course, not meant to reflect on the quality of its contents. In order to present a wide variety of concepts in one volume, a concise style is used and derivations are presented for only the simpler formulae. Ex tensive derivations and explanatory comments may be found in the original references or in the books listed in the selected bibliography which follows. Following the convention in astrophysics, the C. g. S. (centimeter-gram-second) system of units is used unless otherwise noted. To conserve space, the funda mental constants are not always defined, and unless otherwise noted the fol lowing symbols have the following meaning and value.
