Book Synopsis Asymptotic Giant Branch Stars by : Harm J. Habing
Download or read book Asymptotic Giant Branch Stars written by Harm J. Habing and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: The underlying astrophysical mechanisms of the objects known as asymptotic giant branch stars - the structures that occur during the dramatic period prior to a star's death - is the main theme of this text. Over the past three decades, asymptotic giant branch stars have become a topic of their own, and the contributions to this volume all focus on these entities themselves, rather than their connections to other fields of astronomy. Among the many topics covered are new methods of high- quality infrared observation and the more detailed and realistic simulations made possible by increasingly fast computers. This collection should be useful to graduate students who work in the field, teachers who want to address the subject in their courses, and to astronomers from various backgrounds who are interested in the astrophysics of AGB stars.

Book Synopsis Astronomy with Radioactivities by : Roland Diehl
Download or read book Astronomy with Radioactivities written by Roland Diehl and published by Springer Science & Business Media. This book was released on 2010-10-02 with total page 577 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the reader to the field of nuclear astrophysics, i.e. the acquisition and reading of measurements on unstable isotopes in different parts of the universe. The authors explain the role of radioactivities in astrophysics, discuss specific sources of cosmic isotopes and in which special regions they can be observed. More specifically, the authors address stars of different types, stellar explosions which terminate stellar evolutions, and other explosions triggered by mass transfers and instabilities in binary stars. They also address nuclear reactions and transport processes in interstellar space, in the contexts of cosmic rays and of chemical evolution. A special chapter is dedicated to the solar system which even provides material samples. The book also contains a description of key tools which astrophysicists employ in those particular studies and a glossary of key terms in astronomy with radioactivities.
Book Synopsis Understanding Stellar Evolution by : Henny J. G. L. M. Lamers
Download or read book Understanding Stellar Evolution written by Henny J. G. L. M. Lamers and published by CRC Press. This book was released on 2018-02-28 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Understanding Stellar Evolution' is based on a series of graduate-level courses taught at the University of Washington since 2004, and is written for physics and astronomy students and for anyone with a physics background who is interested in stars. It describes the structure and evolution of stars, with emphasis on the basic physical principles and the interplay between the different processes inside stars such as nuclear reactions, energy transport, chemical mixing, pulsation, mass loss, and rotation. Based on these principles, the evolution of low- and high-mass stars is explained from their formation to their death. In addition to homework exercises for each chapter, the text contains a large number of questions that are meant to stimulate the understanding of the physical principles. An extensive set of accompanying lecture slides is available for teachers in both Keynote(R) and PowerPoint(R) formats.

Book Synopsis Structure and Evolution of Asymptotic Giant Branch Stars by : Kawthar Rashid Mehio
Download or read book Structure and Evolution of Asymptotic Giant Branch Stars written by Kawthar Rashid Mehio and published by . This book was released on 2007 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, we focus on the study of structure and evolution of low mass sta rs of masses 2M (solar) and 3M (solar) and initial solar-like composition. The m ost interesting evolutionary phase of such stars is the Asymptotic Giant Branch (AGB) stage. On the Asymptotic Giant Branch, these stars exhibit remarkably high lum inosities and suffer the so called Thermal Pulsation. During these pulsations, s uch stars are considered to synthesize the bulk of heavy elements by the so call ed s-process nucleosynthesis. Also, other elements are produced like Carbon, Oxy gen, and Fluorine. Our study will deal with the influence of mass loss and convection tre atment on the evolution through the AGB phase. Since such stars are numerous and very bright, they can be observed in external galaxies. Their association with a fundamental site of nucleosynthesis in the un iverse illuminates their importance for the chemical evolution of the galaxy. We studied the 2M (solar) star up to the Asymptotic Giant Branch phase. We foll owed its evolution through the 'Helium Flash' and the thermal pulsating phase. Y et the third dredge up was not obtained. So, we adopted a new mass loss formula that is believed to affect the occurrence of the third dredge up. We applied tha t on a 3M (solar) star but our results were not as expected, but we studied in t he process the effect of neutrino losses on the thermal pulsating phase and the interpulse period. Eventually, we applied convective mixing in to radiative regi ons by two methods, instantaneous mixing and exponential mixing. In the exponent ial mixing, we used two different mixing parameters and we obtained that as the parameter increases, the earlier we obtain the third dredge up, the longer is th e interpulse period, and the more dredged up materials to the surface. This is t o be expected, since longer interpulse period means the more materials are proce ssed, thus more dredged up. As for the instantaneous overshooting, the third dre dge up was obtained and compared to the exponential overshooting.

This is followed by a detailed presentation and discussion of a broad range of related techniques, that are widely applied by researchers in the field to investigate the formation and evolution of galaxies. This book will be invaluable for undergraduates and graduate students in astronomy and astrophysics, and will also be of interest to researchers working in the field of Galactic, extragalactic astronomy and cosmology. comprehensive presentation of stellar evolution theory introduces the concept of stellar population and describes "stellar population synthesis" methods to study ages and star formation histories of star clusters and galaxies presents stellar evolution as a tool for investigating the evolution of galaxies and of the universe in general
Book Synopsis The Galactic Evolution Ofs-process Elements Via Asymptotic Giant Branch Stars by : Grant Bazan
Download or read book The Galactic Evolution Ofs-process Elements Via Asymptotic Giant Branch Stars written by Grant Bazan and published by . This book was released on 1991 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We attempt to study the ability of asymptotic giant branch stars to produce s-process elements as a function of initial mass and metallicity. The normal methods of extracting information from spectroscopic observations of the surfaces of these stars are reviewed and it is shown how misleading some of the past claims are and which methods of analysis might eliminate the current confusion. Results from stellar evolution models are brought together in order to establish trends of certain parameters as functions of one or two other parameters. Using these parameterizations, we have determined the s-process abundances created by these stars for different scenarios, and we have related them to surface features that are observable. It is found that the two commonly advocated sources for s-process neutrons cannot produce observational features of MS and S stars as the scenarios are put forth in the literature. It is found, however, that perturbations of these models within the physical limitations of the more popular scenarios can result in observational features of MS and S stars. We also look at the limitations put upon various s-process scenarios by galactic chemical evolution, where we find that AGB stars as an s-process source are consistent with the trends in the heavy elements as a function of the metallicity history of the galaxy. It is also realized that the nucleosynthetic yield of any s-process source must be relatively insensitive to the initial composition of the progenitor star.
