Book Synopsis Chemical Abundances in the Universe (IAU S265) by : Katia Cunha
Download or read book Chemical Abundances in the Universe (IAU S265) written by Katia Cunha and published by Cambridge University Press. This book was released on 2010-03-25 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: IAU Symposium 265 presents a unified picture of nucleosynthesis, the production of chemical elements over cosmic time. It explains how this chemical evolution links together the early Universe of the first stars, through the formation of galaxies and their diverse populations of stars, to a Universe of heavy-element rich stars and planets. The first generation of massive stars that drove reionization left their chemical signatures imprinted in the oldest low-mass stars, which we observe today. Chemical evolution is a broad, diverse and rapidly evolving field, due to the ever-expanding capabilities delivered by new arrays of instruments on large telescopes, together with significant advances in modelling and increasing access to large and accurate nuclear, atomic, and molecular databases. Written for researchers and graduate students, the topics covered in this volume provide a comprehensive overview of the scientific progress achieved in recent years.

Book Synopsis The Cosmic-Chemical Bond by : D A Williams
Download or read book The Cosmic-Chemical Bond written by D A Williams and published by Royal Society of Chemistry. This book was released on 2015-10-09 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introducing astrochemistry to a wide audience, this book describes how molecules formed in chemical reactions occur in a range of environments in interstellar and circumstellar space, from shortly after the Big Bang up to the present epoch. Stressing that chemistry in these environments needs to be driven, it helps identify these drivers and the various chemical networks that operate giving rise to signature molecules that enable the physics of the region to be better understood. The book emphasises, in a non-mathematical way, the chemistry of the Milky Way Galaxy and its planet-forming regions, describes how other galaxies may have rather different chemistries and shows how chemistry was important even in the Early Universe when most of the elements had yet to be formed. This book will appeal to anyone with a general interest in chemistry, from students to professional scientists working in interdisciplinary areas and non-scientists fascinated by the evolving and exciting story of chemistry in the cosmos.

Available in PDF, EPUB and Kindle. Book excerpt: Origin and Distribution of the Elements, Volume 30 presents detailed studies of trace elements and isotopes and the use of these data with the techniques of physical and organic chemistry to make relevant interpretations in geology. This book discusses some of the problems of applied chemistry. Organized into five sections encompassing 89 chapters, this volume begins with an overview of the theories of nucleosynthesis that are based on broad empirical foundations involving experiment in nuclear physics and observation in geophysics and astronomy. This text then explores the primeval abundance of the elements wherein the composition of the material from which the Galaxy is formed. Other chapters consider the production of helium in the galaxy. This book discusses as well the dynamics of the cores of highly evolved massive stars. The final chapter deals with the measurements of site populations in crystal structures by electron diffraction and X-ray. Physicists, astronomers, geologists, and geochemists will find this book extremely useful.
Book Synopsis Chemical Evolution of Galaxies by : Francesca Matteucci
Download or read book Chemical Evolution of Galaxies written by Francesca Matteucci and published by Springer Science & Business Media. This book was released on 2012-01-05 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: The term “chemical evolution of galaxies” refers to the evolution of abundances of chemical species in galaxies, which is due to nuclear processes occurring in stars and to gas flows into and out of galaxies. This book deals with the chemical evolution of galaxies of all morphological types (ellipticals, spirals and irregulars) and stresses the importance of the star formation histories in determining the properties of stellar populations in different galaxies. The topic is approached in a didactical and logical manner via galaxy evolution models which are compared with observational results obtained in the last two decades: The reader is given an introduction to the concept of chemical abundances and learns about the main stellar populations in our Galaxy as well as about the classification of galaxy types and their main observables. In the core of the book, the construction and solution of chemical evolution models are discussed in detail, followed by descriptions and interpretations of observations of the chemical evolution of the Milky Way, spheroidal galaxies, irregular galaxies and of cosmic chemical evolution. The aim of this book is to provide an introduction to students as well as to amend our present ideas in research; the book also summarizes the efforts made by authors in the past several years in order to further future research in the field.
Book Synopsis Chemical Abundances in Carbon-enhanced Metal-poor Stars by : Anna Kwa
Download or read book Chemical Abundances in Carbon-enhanced Metal-poor Stars written by Anna Kwa and published by . This book was released on 2011 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Metal-poor stars in the Galactic halo were born during the first few generations following the Big Bang, and thus provide key insights regarding conditions in the early Universe. Carbon-enhanced metal-poor (CEMP) stars, a subset of this population, are of even further interest because of their peculiar elemental abundance patterns. We studied high-resolution spectra of ten CEMP stars to learn more about the sources of their carbon excess, and now have preliminary abundances for up to 29 elements in our sample. Carbon enhancement in the stellar atmospheres was taken into consideration when conducting the abundance analysis, but did not appear to have a significant effect on derived abundances. Comparison of heavy element abundance ratios to the solar system pattern will be used to study nucleosynthesis at extremely low metallicities.

Download or read book Chemical Abundances in DLAs and the Distant Universe written by Miroslava Dessauges-Zavadsky and published by . This book was released on 2003 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'objet de cette thèse est l'étude de l'abondance des éléments chimiques dans l'Univers et dans les "dampted Ly[alpha] systems" (DLAs), galaxies à haut redshift détectées grâce aux raies d'absorption qu'elles produisent sur la ligne de visée de quasars. Nous avons obtenu des spectres à haute résolution de six de ces galaxies avec le spectrographe UVES sur le VLT. Ces données et les données de l'archive UVES nous ont permis d'étudier les problèmes cosmologiques suivants : "l'évolution chimique des galaxies" en contraignant l'histoire de la formation stellaire et l'âge de quelques DLAs ; "l'évolution de l'enrichissement en métaux de l'Univers" en examinant la contribution d'objets de densité de colonne de HI plus faible que celle des DLAs, appelés "sub-DLAs" ; et "la détermination des paramètres cosmologiques", tels que la densité baryonique de l'Univers obtenue à partir de l'abondance du deutérium et la température du fond de rayonnement cosmologique à un redshift de 3.025.

This book was released on 2012-12-06 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis The Chemical Evolution of the Galaxy by : Francesca Matteucci
Download or read book The Chemical Evolution of the Galaxy written by Francesca Matteucci and published by Springer Science & Business Media. This book was released on 2001-06-30 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is based partly on a. lecture course given at the University of Tri este, but mostly on my own research experience in the field of galactic chemical evolution. The subject of galactic chemical evolution was started and developed by Beat rice Tinsley in the seventies and now is a flourishing subject. This book is dedi cated to the chemical evolution of our Galaxy and aims at giving an up-to-date review of what we have learned since Tinsley's pioneering efforts. At the time of writing, in fact, books of this kind were not available with the exception of the excellent book by Bernard Pagel on "Nucleosynthesis and Chemical Evolution of Galaxies" (Cambridge University Press, 1997), and the subject of galactic chem ical evolution has appeared only as short chapters in books devoted to other subjects. Therefore, I felt that a book of this kind could be useful. The book summarizes the observational facts which allow us to reconstruct the chemical history of our Galaxy, in particular the abundances in stars and in terstellar medium; in the last decade, a great deal of observational work, mostly abundance determinations in stars in the solar vicinity, has shed light on the pro duction and distribution of chemical elements. Even more recently more abun dance data have accumulated for external galaxies at both low and high redshift, thus providing precious information on the chemical evolution of different types of galaxies and on the early stages of galaxy evolution.
