Book Description
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.

Book Description
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?

Book Description
This proceedings covers topics from chemical abundances in the different components of the Milky Way and in local group galaxies, via observational and theoretical papers on mixing in stars to big bang nucleosynthesis and galaxy formation and evolution. Like all volumes in the series ESO Astrophysics Symposia, this one gives a comprehensive overview of the forefront of research in this subject. It is a valuable reference for both students and researchers.

Book Description
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.

Book Description
Understanding the stars is the bedrock of modern astrophysics. Stars are the source of life. 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.

Book Description
Star clusters are at the heart of astronomy, being key objects for our understanding of stellar evolution and galactic structure. Observations with the Hubble Space Telescope and other modern equipment have revealed fascinating new facts about these galactic building blocks. This book provides two comprehensive and up-to-date, pedagogically designed reviews on star clusters by two well-known experts in the field. Bruce Carney presents our current knowledge of the relative and absolute ages of globular clusters and the chemical history of our Galaxy. Bill Harris addresses globular clusters in external galaxies and their use as tracers of galaxy formation and cosmic distance indicators. The book is written for graduate students as well as professionals in astronomy and astrophysics.
