This book was released on 2009-04-16 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents the most complete and up-to-date accounts of our understanding of the Magellanic Clouds and the astrophysical processes within them. Observations of these nearby dwarf galaxies continue to advance, calibrate and challenge our knowledge of the cosmos. They are rich in gas, they have been actively forming stars throughout their history, and they display a wealth of dynamical features. Poor in metals, they serve as a stepping stone towards understanding the high-redshift Universe. In IAU Symposium 256, scientists from vastly different fields of research discuss galactic dynamics, the physics of the interstellar medium and star formation, and the fundamental properties and evolution of stars. New insight was gained by crossing the traditional boundaries of these fields, placing the findings in the context of the structure and evolution of this interacting pair of galaxies uniquely available to our ever more powerful telescopes and computational machinery.

Download or read book Why Galaxies Care about AGB Stars IAU S343 written by Franz Kerschbaum and published by Cambridge University Press. This book was released on 2019-09-30 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
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.
Download or read book History of the IAU written by Adriaan Blaauw and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: This History has its origin in a suggestion, made in September 1990 by former IAU General Secretary Derek McNally, who felt "that a 75 year history of the Union was needed before the col lective memory of those who knew the Union before the Second World War vanished. It would then be a preparatory volume to a centennial history in 2019. " Indeed, of those who knew the Union that long ago, few are still with us. Six years ago, at Baltimore on August 2, 1988, listening and reminiscing at the Inaugural Ceremonies of the Union's 20th General Assembly, I realized that it was almost exactly half a century ago that, at the age of 24, I attended the Inaugurations at my "first" Assembly: on August 3, 1938 in Stockholm. Now, in 1994, this is almost 56 years ago, three quarters of the Union's age. Only vague recollections - no better than that -lead me back to this event, just before World War II. And so, this is not a history based on recollection, far from it. Recollection was helpful in that it allowed me, better perhaps than a younger author, to appreciate circumstances under which the letters and reports which form the basis for this History were written. The account is largely based on archival documents, collected from a wide variety of sources.

Download or read book Timing Neutron Stars Pulsations Oscillations and Explosions written by Tomaso M. Belloni and published by Springer Nature. This book was released on 2020-10-23 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neutron stars, whether isolated or in a binary system, display a varied and complex phenomenology, often accompanied by extreme variability of many time scales, which takes the form of pulsations due to the object rotation, quasi-periodicities associated to accretion of matter, and explosions due to matter accreted on the surface or to starquakes of highly magnetized objects. This book gives an overview of the current observational and theoretical standpoint in the research on the physics under the extreme conditions that neutron stars naturally provide. The six chapters explore three physical regions of a neutron star: the space around it, where accretion and pulsar companions allow testing of general relativity its surface, where millisecond pulsation and X-ray burts provide clues about general relativistic effects and the equation of state of neutron matter its interior, of course, inaccessible to direct observations, can nevertheless, be probed with all observational parameters related to neutron star variability.

Download or read book Kinematics and Dynamics written by Kenwright and published by . This book was released on 2020-03-18 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most challenging tasks in simulation systems is the generation and coordination of efficient and accurate kinematics and dynamic solutions. Kinematic and dynamic algorithms are an essential multi-discipline resources in robotics, medical analysis and even video games. The mathematics for kinematics and dynamics range from simple trajectory based positions to that of fully articulated rigid body mechanics. We explain a variety of concepts from articulated structures all the way through to inverse dynamics. We also discuss implementation details for use in simulation environments (including core mathematics and geometric principles, like vectors, cross product, and the plane equation). This textbook is designed to introduce the reader to the exciting topic of kinematics and dynamics in virtual environments from a practical perspective. Organized around the central concept of controlled motion, the book includes numerous practical examples in the body of the text as well as explaining technical limitations and engineering solutions. It is also one of the purposes of this book to introduce the reader to the development aspect of kinematics and dynamics and not just the theoretical aspect.
Download or read book Stellar Populations written by International Astronomical Union. Symposium and published by Cambridge University Press. This book was released on 2010 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

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.
Download or read book Formation and Evolution of Galaxy Bulges IAU S245 written by International Astronomical Union. Symposium and published by Cambridge University Press. This book was released on 2008-09-04 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bulges lie at the heart of most galaxies, the building blocks of our universe. With a selection of reviews and topical presentations, IAU Symposium 245 provides an up-to-date overview of our knowledge on galaxy bulges, and a concise introduction to all current research on the subject. The structure, dynamics, and stellar populations of galaxy bulges, both near and far, are analysed through state-of-the-art observations. The leading models for the formation and evolution of galaxy bulges are described in detail, and the constraints observations put on these are dissected. Particular emphasis is placed on exploring evidence for both hierarchical merging and secular processes. Special attention is also devoted to disentangling the complex web relating galaxy bulges and central supermassive black holes, and on the lessons learned from our exquisite knowledge of the bulge of our own Milky Way. This volume is the best one-stop reference on galaxy bulges currently available.
