Hobby-Eberly Telescope Chemical Abundances of Stars in the Halo (CASH) Project


Book Description

The Hobby-Eberly Telescope Chemical Abundances of Stars in the Halo (CASH) project aims to characterize the nature of the early universe through the study of metal-poor stars in the stellar halo of the galaxy. Once completed, this will be the largest set of abundances determined for metal-poor stars from high resolution spectra. In this paper, we present chemical abundances and trends of eleven elements for the first ~80 stars of the ~500 star study. These 80 stars serve as a pilot sample to test the automated stellar parameter and abundance determination pipeline newly developed for the CASH project called CASHCODE. Among the pilot sample, two stars with [Fe/H]




New Horizons in Astronomy


Book Description

"These are the proceedings of the 2007 Frank N. Bash Symposium, held at the University of Texas at Austin, USA, from October 14-16, 2007. The first "BashFest" was held in 2003 in honor of Professor Frank Bash at his retirement. Since then, the symposium has evolved into a bi-annual event featuring exclusively the research of young astronomers and astrophysicists from around the world." "The symposium centered around invited review talks by thirteen postdoctoral researchers covering the vast range of modern astronomical research, from the dynamics of small bodies in the Solar System, to globular clusters in the Milky Way and neighboring galaxies, to theories and observations of galaxy formation in the early Universe, and the instruments being designed for the thirty-meter class telescopes that will be used to study these diverse fields. Poster contributions from undergraduate and graduate students as well as postdoctoral researchers rounded out the conference. These posters also covered a wide variety of topics, including abundances in metal-rich and metal-poor stars, galaxy formation and evolution, multi-wavelength observations, and theoretical studies of supernovae and the early Universe." "These proceedings are suitable for young and experienced researchers alike who wish to view a snapshot of a wide range of astronomical topics as seen through the eyes of emerging scientists and framed by their vision of the future of the science of astronomy."--BOOK JACKET.




The Galaxy Disk in Cosmological Context (IAU S254)


Book Description

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.




The Ninth Torino Workshop on Evolution and Nucleosynthesis in AGB Stars and The Second Perugia Workshop on Nuclear Astrophysics


Book Description

All papers have been peer-reviewed. This book contains the lectures given at the joint meeting “Ninth Torino Workshop on Evolution and Nucleosynthesis in AGB Stars” and “Second Perugia Workshop in Nuclear Astrophysics”, held together in Perugia (Italy) from October 21 to October 26, 2007. In the present book, the fields covered by the lecturers are quite wide: the joining of the “Torino Workshops” strictly focused on AGB stars, and of the “Perugia Workshops” dedicated to a broader view of Nuclear Astrophysics, resulted in a coordinated, but widely interdisciplinary discussion, where AGB nucleosynthesis could be integrated by complementary issues concerning nuclear processes in massive stars, while the observational sessions usually dominated by spectroscopic results on stellar atmospheres and laboratory measurements on solar and pre-solar system materials could be complemented by the rich information now coming from space-borne infrared photometry.




Origin of Matter and Evolution of Galaxies


Book Description

All papers have been peer-reviewed. Chemical elements are fundamental matter to comprise the universe and hold a great deal of interest for astronomers and nuclear physicists, for these play an important role in understanding the dawn of the universe to the formation of solar system. This volume contains the proceedings of the symposium that aims to understand the origin and evolution of the universe through the current knowledge of nuclear astrophysics.




Exoplanet Science Strategy


Book Description

The past decade has delivered remarkable discoveries in the study of exoplanets. Hand-in-hand with these advances, a theoretical understanding of the myriad of processes that dictate the formation and evolution of planets has matured, spurred on by the avalanche of unexpected discoveries. Appreciation of the factors that make a planet hospitable to life has grown in sophistication, as has understanding of the context for biosignatures, the remotely detectable aspects of a planet's atmosphere or surface that reveal the presence of life. Exoplanet Science Strategy highlights strategic priorities for large, coordinated efforts that will support the scientific goals of the broad exoplanet science community. This report outlines a strategic plan that will answer lingering questions through a combination of large, ambitious community-supported efforts and support for diverse, creative, community-driven investigator research.

Ancient Mesopotamia


Book Description

"This splendid work of scholarship . . . sums up with economy and power all that the written record so far deciphered has to tell about the ancient and complementary civilizations of Babylon and Assyria."—Edward B. Garside, New York Times Book Review Ancient Mesopotamia—the area now called Iraq—has received less attention than ancient Egypt and other long-extinct and more spectacular civilizations. But numerous small clay tablets buried in the desert soil for thousands of years make it possible for us to know more about the people of ancient Mesopotamia than any other land in the early Near East. Professor Oppenheim, who studied these tablets for more than thirty years, used his intimate knowledge of long-dead languages to put together a distinctively personal picture of the Mesopotamians of some three thousand years ago. Following Oppenheim's death, Erica Reiner used the author's outline to complete the revisions he had begun. "To any serious student of Mesopotamian civilization, this is one of the most valuable books ever written."—Leonard Cottrell, Book Week "Leo Oppenheim has made a bold, brave, pioneering attempt to present a synthesis of the vast mass of philological and archaeological data that have accumulated over the past hundred years in the field of Assyriological research."—Samuel Noah Kramer, Archaeology A. Leo Oppenheim, one of the most distinguished Assyriologists of our time, was editor in charge of the Assyrian Dictionary of the Oriental Institute and John A. Wilson Professor of Oriental Studies at the University of Chicago.




Einstein's Jury


Book Description

Einstein's Jury is the dramatic story of how astronomers in Germany, England, and America competed to test Einstein's developing theory of relativity. Weaving a rich narrative based on extensive archival research, Jeffrey Crelinsten shows how these early scientific debates shaped cultural attitudes we hold today. The book examines Einstein's theory of general relativity through the eyes of astronomers, many of whom were not convinced of the legitimacy of Einstein's startling breakthrough. These were individuals with international reputations to uphold and benefactors and shareholders to please, yet few of them understood the new theory coming from the pen of Germany's up-and-coming theoretical physicist, Albert Einstein. Some tried to test his theory early in its development but got no results. Others--through toil and hardship, great expense, and perseverance--concluded that it was wrong. A tale of international competition and intrigue, Einstein's Jury brims with detail gleaned from Crelinsten's far-reaching inquiry into the history and development of relativity. Crelinsten concludes that the well-known British eclipse expedition of 1919 that made Einstein famous had less to do with the scientific acceptance of his theory than with his burgeoning public fame. It was not until the 1920s, when the center of gravity of astronomy and physics shifted from Europe to America, that the work of prestigious American observatories legitimized Einstein's work. As Crelinsten so expertly shows, the glow that now surrounds the famous scientist had its beginnings in these early debates among professional scientists working in the glare of the public spotlight.
