Download or read book Ecology of Blue Straggler Stars written by Henri M. J. Boffin and published by Springer. This book was released on 2014-12-03 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: The existence of blue straggler stars, which appear younger, hotter, and more massive than their siblings, is at odds with a simple picture of stellar evolution. Such stars should have exhausted their nuclear fuel and evolved long ago to become cooling white dwarfs. They are found to exist in globular clusters, open clusters, dwarf spheroidal galaxies of the Local Group, OB associations and as field stars. This book summarises the many advances in observational and theoretical work dedicated to blue straggler stars. Carefully edited extended contributions by well-known experts in the field cover all the relevant aspects of blue straggler stars research: Observations of blue straggler stars in their various environments; Binary stars and formation channels; Dynamics of globular clusters; Interpretation of observational data and comparison with models. The book also offers an introductory chapter on stellar evolution written by the editors of the book.

The chemical enrichment of our Milky Way and of the Universe withallelementsheavierthanlithiumoriginatesintheinteriorsofstars.Stars arethe tracersofthe dynamics ofthe Universe,gravitationallyimplying much more than meets the eye. Stars ionize the interstellar medium and re-ionized the early intergalactic medium. Understanding stellar structure and evolution is fundamental. While stellar structure and evolution are understood in general terms, we lack important physical ingredients, despite extensive research during recent decades.Classicalspectroscopy,photometry,astrometryandinterferometryof stars have traditionally been used as observational constraints to deduce the internal stellar physics. Unfortunately, these types of observations only allow the tuning of the basic common physics laws under stellar conditions with relatively poor precision. The situation is even more worrisome for unknown aspects of the physics and dynamics in stars. These are usually dealt with by using parameterised descriptions of, e.g., the treatments of convection, rotation,angularmomentumtransport,theequationofstate,atomicdi?usion andsettlingofelements,magneto-hydrodynamicalprocesses,andmore.There is a dearth of observational constraints on these processes, thus solar values areoftenassignedtothem.Yetitishardtoimaginethatonesetofparameters is appropriate for the vast range of stars.
Download or read book The Classification of Stars written by Carlos Jaschek and published by Cambridge University Press. This book was released on 1990-07-26 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 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.
Download or read book Gravitational N Body Simulations written by Sverre J. Aarseth and published by Cambridge University Press. This book was released on 2003-10-23 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses in detail all the relevant numerical methods for the classical N-body problem. It demonstrates how to develop clear and elegant algorithms for models of gravitational systems, and explains the fundamental mathematical tools needed to describe the dynamics of a large number of mutually attractive particles. Particular attention is given to the techniques needed to model astrophysical phenomena such as close encounters and the dynamics of black hole binaries. The author reviews relevant work in the field and covers applications to the problems of planetary formation and star cluster dynamics, both of Pleiades type and globular clusters. Self-contained and pedagogical, this book is suitable for graduate students and researchers in theoretical physics, astronomy and cosmology.
Download or read book The Complex Lives of Star Clusters written by David Stevenson and published by Springer. This book was released on 2015-05-09 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: As with the author’s recent books Extreme Explosions and Under a Crimson Sun, the complex topic of star clusters is broken down and made accessible with clear links to other areas of astronomy in a language which the non-specialist can easily read and enjoy. The full range of topics are addressed regarding how star clusters are formed. Why is it some are dense conglomerates of stars while others are looser associations? Are the young, brilliant clusters seen in neighboring galaxies such as the Large Magellanic Cloud, M33 or M82 analogous to the ancient globulars seen in the Milky Way? How will these clusters change as their stars wane and die? More interestingly, how does living in a dense star cluster affect the fates of the stars and any attendant planets that accompany them? Star clusters form many of the most dazzling objects in the astronomers’ catalogs. Many amateur astronomers are interested in exploring how these objects are created and what it would be like to live among these objects. From the historical views of how star clusters came about to the most recent assumptions about how stars within these clusters evolve, different strands of science, from observation to theory, are woven together into a compelling investigation specifically targeted at amateur astronomers.

This book was released on 2007-11-24 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: Canadian academic Martin Beech has written a text that attempts to cross the line between science fiction and science fact. Put simply, his book details a method that just might be able to stop the Sun from losing its power and, ultimately, save humanity and the Earth itself. It investigates the idea that the distant future evolution of our Sun might be controlled (or ‘asteroengineered’) so that it maintains its present-day energy output rather than becoming a bloated red giant star: a process that would destroy all life on Earth.

Download or read book Evolutionary Processes in Interacting Binary Stars written by Y. Kondo and published by Springer Science & Business Media. This book was released on 1992-06-30 with total page 570 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of IAU Symposium No. 151 `Evolutionary Processes in Interacting Binary Stars,' which was held from 5 to 9 August 1991 in Cordóba, Argentina. The primary aim of this conference was to review and evaluate our current understanding of the evolutionary processes in wide variety of interacting binary stars from their births to their deaths. Subjects included the formation of binaries, mass flow and transfer, accretion processes, and binaries with collapsed components, such as novae, X-ray binaries and binary pulsars. As the field covered is both broad and diverse, there were in all thirty-seven invited talks; sixty-two contributed papers were also presented. In addition, these proceedings contain comments from a panel discussion of the major unsolved problems of interacting binary stars.
Download or read book The Harlow Shapley Symposium on Globular Cluster Systems in Galaxies written by Jonathan E. Grindlay and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 767 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the centennial year, 1985-86, of Harlow Shapley's birth, the study of globular clusters was no less important to the development of astronomy than in 1915, when Shapley first noted their concentration on the sky. By 1917 Shapley had used the properties of the system of globular clusters to complete the Copernican revolution and locate the solar system, and its Earth-bound observers, far from the center of the Galaxy and the globular cluster distribution. Seven decades later, in the year of these proceedings, globular cluster research and the study of the system of globular clusters in our own and distant galaxies is undergoing a renaissance of activity. The introduction of new observational tools, particularly CCD imagers and digital spectrographs, as well as powerful theoretical methods have transformed the study of globular clusters into one of the main line areas of modern astrophysics. Thus it seemed particularly appropriate to one of us, when considering how the Harvard College Observatory might mark the Shapley centennial, to propose and plan for an IAU Symposium on Globular Cluster Systems in Galaxies. Planning for the Shapley Symposium, as it came to be called, was even more drawn out than the preparation of this volume. The Symposium was originally proposed to the IAU Secretariat in time for it to be held in August, 1985, so that it might occur in the centennial (calendar) year.

Download or read book Old Stellar Populations written by Santi Cassisi and published by John Wiley & Sons. This book was released on 2013-08-29 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book discusses the theoretical path to decoding the information gathered from observations of old stellar systems. It focuses on old stellar systems because these are the fossil record of galaxy formation and provide invaluable information ont he evolution of cosmic structures and the universe as a whole. The aim is to present results obtained in the past few years for theoretical developments in low mass star research and in advances in our knowledge of the evolution of old stellar systems. A particularly representative case is the recent discovery of multiple stellar populations in galactic globular clusters that represents one of the hottest topics in stellar and galactic astrophysics and is discussed in detail. Santi Cassisi has authored about 270 scientific papers, 150 of them in peer-reviewed journals, and the title Evolution of Stars and Stellar Populations.

Download or read book Observing Variable Stars written by Gerry A. Good and published by Springer Science & Business Media. This book was released on 2003 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Observing variable stars is one of the major contributions amateur astronomers make to science. There are 36,000 variable stars listed in the General Catalogue of Variable Stars, so it is clearly impossible for the limited number of professional observatories to target even the majority of them. That's where amateur astronomers come in - thousands of them turning their telescopes to the sky every night. Variable star observing is the most popular of "real science" activities for amateurs, and Gerry Good's book provides everything needed. The first part of the book provides a highly detailed account of the various classes of variable star, with examples, illustrations and physical descriptions. The second section covers practical aspects of observing, everything from preparation and planning, through observing techniques, to data management and reduction.
Download or read book Blue Straggler written by MST Publishing and published by Kathy Lynn Harris. This book was released on 2011-08-06 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kathy Lynn Harris' clever debut novel is a laugh-out-loud, yet poignant, story about good friends, bad choices, quirky families and new beginnings - a Texas version of Anna Maxted's Getting Over It with the wit and humor of a Melissa Banks story.Just what is a blue straggler? A blue straggler is a star that appears to be disconnected from those stars surrounding it in its globular cluster and has an anomalous blue color and high luminosity relative to those stars that surround it.But this is not a story about astronomy.Bailey Miller is "disconnected" from the cluster of her rural south Texas family. She has never quite fit in and now in her early 30s, she finds herself struggling with inner turmoil and a series of bad choices in her life.She blames many of her personal demons, and there are many, on a self-proclaimed condition called "RODA"- short for Recurring, Obstinate Dread and Anguish. She's drinking too much (even for a member of her family), has a penchant to eat spoonful after spoonful of Cool Whip, works in a job that bores her beyond description and can't keep a relationship longer than it takes for milk to expire in her fridge.Even with the help of her two outspoken friends, Idamarie - owner of a local cafe and fourth-generation Texas woman with the big hair to prove it - and her quirky college pal Rudy, she's having a hard time.As a series of sometimes humorous, often semi-tragic, events send her reeling, Bailey packs up her Honda and heads out of Texas, in search of herself and answers to secrets from her great-grandmother's past.Chock full of memorable characters, this novel takes readers on a journey from San Antonio to a small mountain town in Colorado and back, as Bailey uncovers not only the secrets of her great-grandmother's life, but also her own, and finding love along the way.In the end, you'll ask yourself, as Bailey does: Are bad choices passed down through generations like tarnished wedding silver, frayed quilts and not-so-tasteful costume jewelry? Can we really define family and home for ourselves, or does the past always determine who we are today?
