Why Galaxies Care about AGB Stars (IAU S343) by Franz Kerschbaum,Martin Groenewegen,Hans Olofsson Pdf

Stars on the asymptotic giant branch (AGB stars) play an important role due to their high luminosity and production of heavy elements and cosmic dust. They are prime laboratories for studying situations where different physical and chemical processes work simultaneously, on different time scales. IAU Symposium 343 builds a bridge between research on AGB stars themselves and their applications to the modelling of stellar populations and the chemical evolution of galaxies. Our understanding of these complex stars is given using insights into many aspects of physics and chemistry, while very high-angular resolution observations of AGB stars and their surroundings provide strong constraints on stellar theory and how they lose matter through strong stellar winds. This volume also highlights the difficulties in estimating the importance of AGB stars for various aspects of galaxies. Current developments and challenges of these complex objects are discussed for a broad, interdisciplinary audience of astronomers.

Why Galaxies Care about AGB Stars by Franz Kerschbaum,Corinne Charbonnel,Robert F. Wing Pdf

"These proceedings of an international conference held August 2006 in Vienna, Austria demonstrate the relevance of Asymptotic Giant Branch stars and stellar astrophysics as a whole for our understanding of galactic structure and evolution. The meeting brought together astronomers from the fields of AGB stars, galactic evolution, and stellar populations. What do we know about the various aspects of AGB stars, such as nucleosynthesis and mass loss, that will play a role in our understanding of galaxies? At the same time, what do galactic models need from the AGB star community, and how are AGB starts included in these models? What will be the role of AGB star research within the major aims of astrophysics in the coming decades? These were the main questions we wanted to discuss at this conference. Recent developments in instrumentation such as the Spitzer satellite and current and forthcoming ground-based equipment are enabling detailes studies of individual stars and the exploration of ever more distant stellar systems. AGB stars are among the first targets that can now be resolved in galaxies outside the Local Group. But of equal relevance are the exciting developments that have been achieved in modeling stellar nucleosynthesis, mass loss, and the evolution of galaxies. The book is suitable for researchers and graduate students interested in stellar and extragalactic astrophysics, and in physical processes related to nucleosynthesis, radiation hydrodynamics, pulsation, mass loss, and the chemical evolution of stellar systems." -- supplied by publisher.

Stellar Populations by International Astronomical Union. Symposium Pdf

IAU Symposium 262 presents reviews on the current understanding of the theories of stellar evolution, galaxy formation and galaxy evolution. It emphasises what we have learned in the past few years from massive surveys covering large portions of the sky (e.g. SDSS, HDF, UDF, GOODS, COSMOS). Several critical aspects of research on stellar populations deserve further effort in order to be brought in tune with other areas of astrophysical research. The next ten years will see the opening of major observatories that will increase the quality and quantity of astronomical data by orders of magnitude. The expected benefits from these instruments for the study of stellar populations are explored. This critical review of state of the art observational and theoretical work will appeal to all those working on stellar populations, from distant galaxies to local resolved galaxies and galactic star clusters.

Planetary Nebulae in Our Galaxy and Beyond (IAU S234) by International Astronomical Union. Symposium Pdf

Planetary nebulae represent the brief transition between Asymptotic Giant Branch stars and White Dwarfs. As multi-wavelength laboratories they have played a key role in developing our understanding of atomic, molecular, dust and plasma processes in astrophysical environments. The means by which their wonderfully diverse morphologies are obtained is currently the subject of intense research, including hydrodynamical shaping mechanisms and the role of binarity, stellar magnetic fields and rotation. Their contribution to the chemical enrichment of galaxies is another very active research area, as is the ever growing use of their narrow high luminosity emission lines to probe the dynamics and mass distributions of galaxies and the intergalactic media of clusters of galaxies. IAU S234 summarises the current status of research on the properties and processes of planetary nebulae, as reported in reviews and papers by leading experts working in the field.

The Interplay Among Black Holes, Stars and ISM in Galactic Nuclei (IAU S222) by International Astronomical Union. Symposium Pdf

How massive are the largest and smallest nuclear black holes in galaxies? Why are the masses of nuclear black holes proportional to those of their host galaxy bulges? How is nuclear activity triggered? What are the observational signatures of such processes? What are the connections between the active nucleus, stars and interstellar medium in galaxies? Answers to these questions are addressed in this book, which presents a compilation of 191 works covering recent observations from X-rays to radio wavelengths, as well as theoretical modeling of accretion disks, stellar populations and galaxy and black hole evolution. This volume presents the nuclear activity as a phase in the life of a galaxy, which is intimately connected to the evolution of its stars and interstellar medium. It brings together recent developments in topics covering most aspects of galaxy evolution, and is a valuable resource for astronomers and graduate students working in extragalactic astronomy.

Evolution of Peculiar Red Giant Stars by International Astronomical Union. Colloquium Pdf

Red giant stars are evolutionarily advanced objects in the closing stages of their nuclear burning lifetime. Observed with increasing spectral coverage they display a variety of unusual phenomena. Many are characterized by peculiar (non-solar) surface chemical compositions which provide otherwise unobtainable clues to interior nucleosynthesis, mixing and evolution. Others may have received their chemical peculiarities by mass transfer from a companion. This book reports on the proceedings of the International Astronomical Union Colloquium 106. It contains discussions on many aspects of these stars, combining theory and observation to interpret these objects in terms of their evolutionary history. There are 20 review papers, 69 abstracts and short contributed papers and a complete transcript of the valuable summary panel discussion. Professional astronomers will find this book useful as a reference work which incorporates current research on the modelling and evolution of these unstable stars.

Low-metallicity Star Formation (IAU S255) by International Astronomical Union. Symposium Pdf

Although low-mass metal-poor galaxies in the local universe have often been proposed as the 'primordial building blocks' in the hierarchical scenario of structure formation, several lines of evidence suggest that this may not be true. Moreover, it is not clear to what extent dwarf galaxies, because they are metal poor and because of their kinematics and structure, can tell us about how star formation proceeded in the early universe. This volume provides an overview and the most recent advances in this debate. IAU Symposium 255 presents the most up-to-date developments in six key areas, including: Population III and metal-free star formation; metal-enrichment, chemical evolution and feedback; explosive events in low-metallicity environments; dust and gas as seeds for metal-poor star formation; metal-poor initial mass functions, stellar evolution and star-formation histories; and low-metallicity star formation in the local universe. This overview is at a level suitable for research astronomers and graduate students.

The General Assembly of Galaxy Halos (IAU S317) by Angela Bragaglia,Magda Arnaboldi,Marina Rejkuba,Donatella Romano Pdf

The proceedings of IAU S317 offer an updated view of the stellar halos of galaxies, from the local universe to more distant systems, discussing differences and similarities among them. They review the results of ongoing large photometric and spectroscopic surveys and compare them to the predictions of new generation simulations at the forefront of our technical capabilities. Structures are analysed on both large and small scales, with attention given to the kinematical and chemical properties of their smallest and oldest components. A number of excellent reviews on state-of-the-art research, covering fields such as first stars, galactic archaeology, stellar halos in cosmological simulations, discrete constituents of stellar halos - from field, isolated stars to globular clusters and planetary nebulae - are accompanied by contributed papers presenting the results of original research by top-level specialists in the area. IAU S317 benefits researchers with interests encompassing stellar and galactic astrophysics and galaxy evolution.

Formation and Evolution of Galaxy Outskirts (IAU S321) by Armando Gil de Paz,Johan H. Knapen,Janice C. Lee Pdf

The borders between galaxies and the almost empty intergalactic medium are ill-defined regions where gas struggles to form stars. The proceedings of IAU Symposium 321 summarize our current understanding of the rarefied universe and prepare for the optimal exploitation of upcoming astronomical instruments. They discuss the most recent advances in the study of the stellar, dust and gas content of galaxy outskirts, going from resolved stellar populations in the Milky Way and in the Local Group to the study of high-redshift systems. Such a broad approach, both in terms of galaxy components and evolutionary epochs, is necessary to take full advantage of the recent discoveries made by facilities at all wavelengths, to deepen our knowledge of the assembly and evolution of these elusive regions and to establish their role within the evolution of galaxies as a whole and their interactions with the surrounding intergalactic medium.

Galaxies at High Redshift and their Evolution over Cosmic Time (IAU S319) by Sugata Kaviraj Pdf

IAU Symposium 319 was the largest galaxy evolution meeting at the IAU General Assembly in 2015. This volume presents a summary of the current state of the art in galaxy evolution studies, and provides a perspective on future large spectro-photometric surveys which will become available in the next decade. Topics covered include the emergence of galaxies and their constituent black holes during the first few billion years, the evolving interstellar medium as seen through modern instrumentation like Herschel, Planck and ALMA, and a look ahead to future ground- and space-based instruments that will become the workhorse facilities of the next decade, such as JWST and the SKA precursors. This volume will appeal to those who are interested in the formation and evolution of galaxies over cosmic time, as well as those who are active in developing, or on the science teams for, new astronomical instrumentation.

Cosmic Dawn by George Rhee Pdf

This book takes the reader on an exploration of the structure and evolution of our universe. The basis for our knowledge is the Big Bang theory of the expanding universe. This book then tells the story of our search for the first stars and galaxies using current and planned telescopes. These telescopes are marvels of technology far removed from Galileo's first telescope but continuing astronomy in his ground breaking spirit. We show the reader how these first stars and galaxies shaped the universe we see today. This story is one of the great scientific adventures of all time.
