DOWNLOAD EBOOKThe International Astronomical Union Symposium No. 70 on Be and Shell Stars, the Merrill-McLaughlin Memorial Symposium, was held in Bass River (Cap Cod), Massachusetts, U. S. A. , from September 15th through 18th, 1975. Fifty-three astronomers from Argentina, Belgium, Canada, Czechoslovakia, France, Israel, the United Kingdom, the United States, and the Vatican attended and participated in the Symposium. This volume, which parallels the actual program closely, contains the papers presented at the Symposium plus most of the discussion following the papers. New observational techniques and fresh theoretical ideas have resulted over the past few years in a renewed interest in Be and shell stars. At IAU Symposium No. 51 on Extended Atmospheres and Circumstellar Matter in Spectroscopic Binary Sys tems, the Otto Struve Memorial Symposium, in Parksville, British Columbia, Canada, three years ago, a number of participants expressed the wish to organize a symposium on Be and shell stars. If we wish to identify an official 'Father of IAU Symposium No. 70', it would be Mirek Plavec who, in his capacity as President of IAU Commission 42 (Photometric Double Stars) requested and received the cooperation of Commissions 29 (Stellar Spectra) and 36 (Stellar Atmospheres), suggested an Organizing Committee, and wrote to the IAU General Secretary in 1973 requesting that the IAU Executive Committee approve the proposed confer ence as an IAU Symposium.

DOWNLOAD EBOOK“IN A LIFE FULL OF LIES, HE FINALLY SETTLED FOR THE TRUTH.” No one in Mattingly ever believed Bobby Barnes would live to see old age. Drink would either rot Bobby from the inside out or dull his senses just enough to send his truck off the mountain on one of his nightly rides. Although Bobby believes such an end possible—and even likely—it doesn’t stop him from taking his twin sons Matthew and Mark into the mountains one Saturday night. A sharp curve, blinding headlights, metal on metal, his sons’ screams. Bobby’s final thought as he sinks into blackness is a curious one—There will be stars. Yet it is not death that greets him beyond the veil. Instead, he returns to the day he has just lived and finds he is not alone in this strange new world. Six others are trapped with him. Bobby soon discovers that this supposed place of peace is actually a place of secrets and hidden dangers. Along with three others, he seeks to escape, even as the world around him begins to crumble. The escape will lead some to greater life, others to endless death . . . and Bobby Barnes to understand the deepest nature of love.

DOWNLOAD EBOOKAll communities are teeming with energy, spirit, and knowledge, and Spiral to the Stars taps into and activates this dynamism to discuss Indigenous community planning from a Mvskoke perspective. This book poses questions about what community is, how to reclaim community, and how to embark on the process of envisioning what and where the community can be. Geographer Laura Harjo demonstrates that Mvskoke communities have what they need to dream, imagine, speculate, and activate the wishes of ancestors, contemporary kin, and future relatives—all in a present temporality—which is Indigenous futurity. Organized around four methodologies—radical sovereignty, community knowledge, collective power, and emergence geographies—Spiral to the Stars provides a path that departs from traditional community-making strategies, which are often extensions of the settler state. Readers are provided a set of methodologies to build genuine community relationships, knowledge, power, and spaces for themselves. Communities don’t have to wait on experts because this book helps them activate their own possibilities and expertise. A detailed final chapter provides participatory tools that can be used in workshop settings or one on one. This book offers a critical and concrete map for community making that leverages Indigenous way-finding tools. Mvskoke narratives thread throughout the text, vividly demonstrating that theories come from lived and felt experiences. This is a must-have book for community organizers, radical pedagogists, and anyone wishing to empower and advocate for their community.

DOWNLOAD EBOOKMassive stars occupy an exceptional place in general astrophysics. They trigger many if not all of the important processes in galactic evolution whereas due to their intrinsic brightness, they offer the (only until now) possibility to study the stellar content and stellar behaviour in distant galaxies. The last, say, 25 years, massive stars have been the subject of numerous meetings discussing the influence of massive stars on population synthesis, the number distribution of different types of massive stars, the LBV phenomenon, WR stars, X-ray binaries, stellar winds in massive stars, chemical pecularities in massive stars, supernova explosions of massive stars and the important SN1987A event, the influence of massive stars and chemical evolution of galaxies. It is clear that without a theory of stellar evolution, the study of these topics loses a lot of its significance. Massive star evolution therefore got a chance in these meetings, but rarely as a prime subject. The state of the art, the physical processes and the uncertainties in stellar evolution were barely touched. Even more, the influence of close binaries in all these massive star meetings slowly disappeared the last, say, 13 years without any scientific justification, although a significant fraction of stars occurs in close binaries with periods small enough so that both components will interact during their evolution. Denying the binaries or not discussing their influence on results and conclusions, makes the latter very uncertain or even completely unreliable.

DOWNLOAD EBOOKAstronomy and Astrophysics Abstracts, which has appeared in semi-annual volumes since 1969, is devoted to the recording, summarizing and indexing of astronomical publications throughout the world. It is prepared under the auspices of the International Astronomical Union (according to a resolution adopted at the 14th General Assembly in 1970). Astronomy and Astrophysics Abstracts aims to present a comprehensive documenta tion of literature in all fields of astronomy and astrophysics. Every effort will be made to ensure that the average time interval between the date of receipt of the original literature and publication of the abstracts will not exceed eight months. This time interval is near to that achieved by monthly abstracting journals, compared to which our system of accumu lating abstracts for about six months offers the advantage of greater convenience for the user. Volume 31 contains literature published in 1982 and received before July 15, 1982; some older literature which was received late and which is not recorded in earlier volumes is also included. We acknowledge with thanks contributions to this volume by Dr. J. Bouska, Prague, who surveyed journals and publications in Czech and supplied us with abstracts in English .

DOWNLOAD EBOOKThe classification of stars into their various types is one of the fundamental areas of astronomy. This book is a comprehensive handbook on the tools, methods and results of stellar taxonomy. Although this subject is firmly rooted in classical astronomy, vast improvements in observational techniques have transformed the subject and greatly broadened the wavelength regions available for study. The first six chapters describe modern methods of spectroscopic and photometric classification. The remaining nine chapters describe particular families of stars, progressing from the hottest to the coolest. Within each category a description is given of the normal type and all the peculiar stars. Throughout the emphasis is on the phenomenology of classification, rather than the underlying astrophysics. Both authors have devoted themselves to developing the international centre for stellar data at Strasbourg, which uniquely qualifies them to write this definitive handbook for professional astronomers.
