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
This textbook describes the equipment, observational techniques, and analysis used in the investigation of stellar photospheres. Now in its fourth edition, the text has been thoroughly updated and revised to be more accessible to students. New figures have been added to illustrate key concepts, while diagrams have been redrawn and refreshed throughout. The book starts by developing the tools of analysis, and then demonstrates how they can be applied. Topics covered include radiation transfer, models of stellar photospheres, spectroscopic equipment, how to observe stellar spectra, and techniques for measuring stellar temperatures, radii, surface gravities, chemical composition, velocity fields, and rotation rates. Up-to-date results for real stars are included. Written for starting graduate students or advanced undergraduates, this textbook also includes a wealth of reference material useful to researchers. eBook formats include color imagery while print formats are greyscale only; a wide selection of the color images are available online.

Book Description
It is now clear that a binary evolutionary pathway is responsible for a significant fraction of all planetary nebulae, with some authors even going so far as to claim that binarity may be a near requirement for the formation of an observable nebula. This has led to the requirement that textbooks most likely need to be rewritten. Building upon the review of Jones and Boffin in Nature Astronomy (2017), this Springer Brief takes a first step in this direction. It offers the first expanded presentation of all the theoretical and observational support for the importance of binarity in the formation of planetary nebulae, initially focusing on common envelope evolution but also covering wider binaries. This book emphasises the wider impact of the field, highlighting the critical role binary central stars of planetary nebulae have in understanding a plethora of astrophysical phenomena, including type Ia supernovae, chemically peculiar stars and circumbinary exoplanets.

Book Description
This book describes the characteristics and applications of the Δa photometric system, which measures the stellar flux at around 520 nm. Since its introduction in 1976 by Hans-Michael Maitzen, the Δa system has not only been successfully applied to the classical chemically peculiar stars of the upper main sequence, but also to galactic and extragalactic star clusters. New possible applications for studying galaxies, quasars and other astrophysical objects of interest are discussed.

Book Description
FROM THE AUTHOR OF THE #1 NEW YORK TIMES BESTSELLER THE LAST THING HE TOLD ME? Heralded as “impossible to put down” (Elle), and named a Best Book of the Summer by Glamour, Good Housekeeping, Cosmopolitan, Elle, Marie Claire, and Us Weekly, Eight Hundred Grapes is a heartbreaking, funny, and deeply evocative novel about love, marriage, family, wine, and the treacherous terrain in which they all intersect. There are secrets you share, and secrets you hide… What if your beloved fiancé, he of the crinkly smile and irresistible British accent, had kept a life-changing secret from you? And what if, just a week before your dream wedding, you discovered it? Georgia Ford, bride-to-be, hops in her car and drives through the night, from Los Angeles to Sonoma, to her safe haven: her family, and the acclaimed family winery. Georgia craves the company of those who know her best, and whom she truly knows. Better yet, it’s the eve of the last harvest—the best time of the growing season, and Georgia knows she’ll find solace—and distraction—in the familiar rituals. But when Georgia arrives home, nothing is at all familiar. Her parents, her brothers, the family business, are all unrecognizable. It seems her fiancé isn’t the only one who’s been keeping secrets… Eight Hundred Grapes is a story about the messy realities of family, the strength (and weaknesses) of romantic love, and the importance of finding a place to call home. “This winning tale will both satisfy on a literary level and encourage oenophiles to pour themselves a glass of a recent vintage to enjoy while reading; it’s a tasty treat for wine lovers and teetotalers alike” (Publishers Weekly). You won’t be able to put this “addictive” (Us Weekly) novel down.

Book Description
One of the world's most distinguished astrophysicists presents a comprehensive theoretical treatment of the dynamical evolution of globular clusters. Lyman Spitzer's research in this field established the framework for decades of investigation. Now he summarizes in a unified, systematic way this branch of theoretical astrophysics with its still challenging problems. Originally published in 1988. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Book Description
A thought experiment in future-shock survivalism' Robert MacFarlane 'Gripping ... of all science fiction's apocalypses, this is one of the most haunting' Financial Times WITH AN INTRODUCTION BY ROBERT MACFARLANE A post-apocalyptic vision of the world pushed to the brink by famine, John Christopher's science fiction masterpiece The Death of Grass includes an introduction by Robert MacFarlane in Penguin Modern Classics. At first the virus wiping out grass and crops is of little concern to John Custance. It has decimated Asia, causing mass starvation and riots, but Europe is safe and a counter-virus is expected any day. Except, it turns out, the governments have been lying to their people. When the deadly disease hits Britain, society starts to descend into barbarism. As John and his family try to make it across country to the safety of his brother's farm in a hidden valley, their humanity is tested to its very limits. A chilling psychological thriller and one of the greatest post-apocalyptic novels ever written, The Death of Grass shows people struggling to hold on to their identities as the familiar world disintegrates - and the terrible price they must pay for surviving. John Christopher (1922-2012) was the pen name of Samuel Youd, a prolific writer of science fiction. His novels were popular during the 1950s and 1960s, most notably The Death Of Grass (1956), The World in Winter (1962), and Wrinkle in the Skin (1965), all works depicting ordinary people struggling in the midst of apocalyptic catastrophes. In 1966 he started writing science-fiction for adolescents; The Tripods trilogy, the Prince in Waiting trilogy (also known as the Sword of the Spirits trilogy) and The Lotus Caves are still widely read today. Ifyou enjoyed The Death of Grass, you might like John Wyndham's The Day of the Triffids, also available in Penguin Modern Classics.
