Book Synopsis Atomic Diffusion in Stars by : Georges Michaud
Download or read book Atomic Diffusion in Stars written by Georges Michaud and published by Springer. This book was released on 2015-10-27 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors give an overview of atomic diffusion as applied to all types of stars, showing where it plays an essential role and how it can be implemented in modelling. Part I describes the tools that are required to include atomic diffusion in models of stellar interiors and atmospheres. An important role is played by the gradient of partial radiative pressure, or radiative acceleration, which is usually neglected in stellar evolution. In Part II, the authors systematically review the contribution of atomic diffusion to each evolutionary step. The dominant effects of atomic diffusion are accompanied by more subtle effects on a large number of structural properties throughout evolution. The goal of this book is to provide the means for the astrophysicist or graduate student to evaluate the importance of atomic diffusion in a given star. A fundamental physical process, atomic diffusion can significantly affect the superficial abundances of stars and/or their evolution. This guide includes all the information needed to take proper account of atomic diffusion's impact.
Download or read book Asteroseismology written by Pere L. Pallé and published by Cambridge University Press. This book was released on 2014-01-13 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our understanding of stars has grown significantly due to recent advances in asteroseismology, the stellar analog of helioseismology, the study of the Sun's acoustic wave oscillations. Using ground-based and satellite observatories to measure the frequency spectra of starlight, researchers are able to probe beneath a star's surface and map its interior structure. This volume provides a wide-ranging and up-to-date overview of the theoretical, experimental and analytical tools for carrying out front-line research in stellar physics using asteroseismological observations, tools and inferences. Chapters from seven eminent scientists in residence at the twenty-second Canary Islands Winter School of Astrophysics examine the interior of our Sun relative to data collected from distant stars, how to measure the fundamental parameters of single field stars, diffusion processes, and the effects of rotation on stellar structures. The volume also provides detailed treatments of modeling and computing programs, providing astronomers and graduate students a practical, methods-based guide.
Book Synopsis Astronomy in Focus XXX by : Maria Teresa Lago
Download or read book Astronomy in Focus XXX written by Maria Teresa Lago and published by Cambridge University Press. This book was released on 2020-04-16 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Astronomy in Focus presents the most relevant contributions from the Focus Meetings included during the XXX IAU General Assembly held in Vienna, Austria, from 20-31 August 2018. Focus meetings are proposed by groups of scientists with aims to promote cross-disciplinary interactions while maintaining a well-defined focus on a particular topic. They usually address a new scientific area or an emerging field that is not well, or in some cases not at all, represented under the IAU's existing Commission structure. The XXX IAU General Assembly included six scientific symposia, a special symposium focused on the IAU's centenary and fifteen Focus Meetings. The latter comprised twelve scientific Focus Meetings plus two on the mission and activities of the IAU Offices of Astronomy Outreach and Astronomy for Development and the final one promoted by the Working Group on Global Coordination of Ground and Space Astrophysics.
Book Synopsis Supernova Environmental Impacts (IAU S296) by : Alak Ray
Download or read book Supernova Environmental Impacts (IAU S296) written by Alak Ray and published by Cambridge University Press. This book was released on 2014-02-27 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: New telescopes spanning the full electromagnetic spectrum have enabled the study of supernovae (SNe) and supernova remnants (SNRs) to advance at a breathtaking pace. Automated synoptic surveys have increased the detection rate of supernovae by more than an order of magnitude and have led to the discovery of highly unusual supernovae. Observations of gamma-ray emission from SNRs with ground-based Cherenkov telescopes and the Fermi telescope have spawned new insights into particle acceleration in supernova shocks. Far-infrared observations from the Spitzer and Herschel observatories have told us much about the properties and fate of dust grains in SNe and SNRs. Work with satellite-borne Chandra and XMM-Newton telescopes and ground-based radio and optical telescopes reveal signatures of supernova interaction with their surrounding medium, their progenitor life history and of the ecosystems of their host galaxies. IAU Symposium 296 covers all these advances, focusing on the interactions of supernovae with their environments.
Book Synopsis Astrophysical Masers and Their Environments (IAU S242) by : International Astronomical Union. Symposium
Download or read book Astrophysical Masers and Their Environments (IAU S242) written by International Astronomical Union. Symposium and published by Cambridge University Press. This book was released on 2008-02-14 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: Astrophysical masers, naturally occurring microwave and radio-wave emissions, provide an important tool to investigate astrophysical environments. Several thousand maser sources have been observed in the interstellar medium and star formation regions, in the expanding winds from evolved stars, in the compressed shells of supernovae remnants, in comets and in the centers of galaxies. Masers are also useful for studying the structure and dynamics of our own galaxy, while masers in other galaxies are now used for cosmological studies and studies of galactic nuclei. This volume contains the latest research on the topic as presented at IAU Symposium 242, only the third international symposium on astrophysical masers. Over 125 astronomers from 18 different countries gathered in Alice Spring, Australia, for discussions on maser research.
Book Synopsis Relativistic Hydrodynamics by : Luciano Rezzolla
Download or read book Relativistic Hydrodynamics written by Luciano Rezzolla and published by OUP Oxford. This book was released on 2013-09-26 with total page 744 pages. Available in PDF, EPUB and Kindle. Book excerpt: Relativistic hydrodynamics is a very successful theoretical framework to describe the dynamics of matter from scales as small as those of colliding elementary particles, up to the largest scales in the universe. This book provides an up-to-date, lively, and approachable introduction to the mathematical formalism, numerical techniques, and applications of relativistic hydrodynamics. The topic is typically covered either by very formal or by very phenomenological books, but is instead presented here in a form that will be appreciated both by students and researchers in the field. The topics covered in the book are the results of work carried out over the last 40 years, which can be found in rather technical research articles with dissimilar notations and styles. The book is not just a collection of scattered information, but a well-organized description of relativistic hydrodynamics, from the basic principles of statistical kinetic theory, down to the technical aspects of numerical methods devised for the solution of the equations, and over to the applications in modern physics and astrophysics. Numerous figures, diagrams, and a variety of exercises aid the material in the book. The most obvious applications of this work range from astrophysics (black holes, neutron stars, gamma-ray bursts, and active galaxies) to cosmology (early-universe hydrodynamics and phase transitions) and particle physics (heavy-ion collisions). It is often said that fluids are either seen as solutions of partial differential equations or as "wet". Fluids in this book are definitely wet, but the mathematical beauty of differential equations is not washed out.

Book Synopsis The Galaxy Disk in Cosmological Context (IAU S254) by : International Astronomical Union. Symposium
Download or read book The Galaxy Disk in Cosmological Context (IAU S254) written by International Astronomical Union. Symposium and published by Cambridge University Press. This book was released on 2009-04-16 with total page 542 pages. Available in PDF, EPUB and Kindle. Book excerpt: The paradigm of a dark energy- and dark matter-dominated Universe, with the hierarchical merger scenario for the formation of galaxies, has scored impressive successes in matching the observed Universe. However, the theory fails to explain the difficulty in generating ordinary disk galaxies such as the Milky Way, suggesting that some important physics must be missing in current models. IAU Symposium 254 was organized to address this question, gathering researchers from an unusually broad range of fields, from cosmology to interstellar matter, and the formation and evolution of stars. High-class reviews, lectures and posters combine to define the frontiers in the field and point the way to new avenues of research. This volume presents a unique set of succinct overviews illuminating the full range of topics in this very active field. It also honors Danish astrophysicist Bengt Strömgren (1908-1987), who laid much of the foundation for this entire field.

Book Synopsis Nature's Third Cycle by : Arnab Rai Choudhuri
Download or read book Nature's Third Cycle written by Arnab Rai Choudhuri and published by Oxford University Press, USA. This book was released on 2015 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cycle of day and night and the cycle of seasons are two familiar natural cycles around which many human activities are organized. But is there a third natural cycle of importance for us humans? On 13 March 1989, six million people in Canada went without electricity for many hours: a large explosion on the sun was discovered as the cause of this blackout. Such explosions occur above sunspots, dark features on the surface of the Sun that have been observed through telescopes since the time of Galileo. The number of sunspots has been found to wax and wane over a period of 11 years. Although this cycle was discovered less than two centuries ago, it is becoming increasingly important for us as human society becomes more dependent on technology. For nearly a century after its discovery, the cause of the sunspot cycle remained completely shrouded in mystery. The 1908 discovery of strong magnetic fields in sunspots made it clear that the 11-year cycle is the magnetic cycle of the sun. It is only during the last few decades that major developments in plasma physics have at last given us the clue to the origins of the cycle and how the large explosions affecting the earth arise. Nature's Third Cycle discusses the fascinating science behind the sunspot cycle, and gives an insider's perspective of this cutting-edge scientific research from one of the leaders of the field.
