It is the stars, The stars above us, govern our conditions. William Shakespeare, King Lear A Few Words about What, Why and How The structure of the stars in general, and the Sun in particular, has been the subject of extensivescienti?cresearchanddebateforoveracentury.Thediscoveryofquantum theoryduringthe?rsthalfofthenineteenthcenturyprovidedmuchofthetheoretical background needed to understand the making of the stars and how they live off their energysource. Progress in the theoryof stellar structurewasmade through extensive discussions and controversies between the giants of the ?elds, as well as brilliant discoveries by astronomers. In this book, we shall carefully expose the building of the theory of stellar structure and evolution, and explain how our understanding of the stars has emerged from this background of incessant debate. About hundred years were required for astrophysics to answer the crucial ques tions: What is the energy source of the stars? How are the stars made? How do they evolve and eventually die? The answers to these questions have profound im plications for astrophysics, physics, and biology, and the question of how we our selves come to be here. While we already possess many of the answers, the theory of stellar structure is far from being complete, and there are many open questions, for example, concerning the mechanisms which trigger giant supernova explosions. Many internal hydrodynamic processes remain a mystery. Yet some global pictures can indeed be outlined, and this is what we shall attempt to do here.

This volume is devoted to one of the fascinating things about stars: how they evolve as they age. This evolution is different for stars of different masses. How stars end their lives when their supply of energy is exhausted also depends on their masses. Interestingly, astronomers conjectured about the ultimate fate of the stars even before the details of their evolution became clear. Part I of this book gives an account of the remarkable predictions made during the 1920s and 1930s concerning the ultimate fate of stars. Since much of this development hinged on quantum physics that emerged during this time, a detailed introduction to the relevant physics is included in the book. Part II is a summary of the life history of stars. This discussion is divided into three parts: low-mass stars, like our Sun, intermediate-mass stars, and massive stars. Many of the concepts of contemporary astrophysics were built on the foundation erected by Subrahmanyan Chandrasekhar in the 1930s. This book, written during his birth centenary, includes a brief biographical sketch of the brilliant scientist, which readers will find fascinating. Reading this book will get young students excited about the presently unfolding revolution in astronomy and the challenges that await them in the world of physics, engineering and technology. General readers will also find the book appealing for its highly accessible narrative of the physics of stars. This book is a companion volume of “What are the Stars?” by the same author. "I know of no other book on the evolution of stars of a similar scope and breadth that is so accessible for undergraduate students."

Evolution and the Emergent Self

Evolution and the Emergent Self is an eloquent and evocative new synthesis that explores how the human species emerged from the cosmic dust. Lucidly presenting ideas about the rise of complexity in our genetic, neuronal, ecological, and ultimately cosmological settings, the author takes readers on a provocative tour of modern science's quest to understand our place in nature and in our universe. Readers fascinated with "Big History" and drawn to examine big ideas will be challenged and enthralled by Raymond L. Neubauer's ambitious narrative. How did humans emerge from the cosmos and the pre-biotic Earth, and what mechanisms of biological, chemical, and physical sciences drove this increasingly complex process? Neubauer presents a view of nature that describes the rising complexity of life in terms of increasing information content, first in genes and then in brains. The evolution of the nervous system expanded the capacity of organisms to store information, making learning possible. In key chapters, the author portrays four species with high brain:body ratios—chimpanzees, elephants, ravens, and dolphins—showing how each species shares with humans the capacity for complex communication, elaborate social relationships, flexible behavior, tool use, and powers of abstraction. A large brain can have a hierarchical arrangement of circuits that facilitates higher levels of abstraction. Neubauer describes this constellation of qualities as an emergent self, arguing that self-awareness is nascent in several species besides humans and that potential human characteristics are embedded in the evolutionary process and have emerged repeatedly in a variety of lineages on our planet. He ultimately demonstrates that human culture is not a unique offshoot of a language-specialized primate, but an analogue of fundamental mechanisms that organisms have used since the beginning of life on Earth to gather and process information in order to buffer themselves from fluctuations in the environment. Neubauer also views these developments in a cosmic setting, detailing open thermodynamic systems that grow more complex as the energy flowing through them increases. Similar processes of increasing complexity can be found in the "self-organizing" structures of both living and nonliving forms. Recent evidence from astronomy indicates that planet formation may be nearly as frequent as star formation. Since life makes use of the elements commonly seeded into space by burning and expiring stars, it is reasonable to speculate that the evolution of life and intelligence that happened on our planet may be found across the universe.

American film favorite Thelma Todd was much more than the beautiful blonde of the 1930s who played opposite Buster Keaton, Laurel and Hardy and the Marx Brothers. Todd’s tragic death transformed her into an icon of Hollywood mystery: The photograph of the 29-year-old actress slumped in her luxurious Lincoln Phaeton shocked fans in 1935. How did she die? Was it murder, suicide, or an accident? This definitive biography covers a fascinating era in Hollywood history. In the course of his exhaustive research, the author interviewed Todd’s cousins Bill and Edna Todd, as well as such friends and coworkers as Ida Lupino, Lina Basquette, Anita Garvin, Dorothy Granger, William Bakewell and Greg Blackton. Also examined is Hollywood’s first major sex scandal of 1913, involving Jewel Carmen, the future spouse of director Roland West—the man Thelma Todd loved.

Stars are dying. That's the news that greets John Bandicut and his companions—coming straight off a mission and looking for some rest and recovery. No time for that now. They must travel to a nebula called Starmaker—their new mission, to discover what force threatens not just the newborn stars, but every world within a thousand light-years. They must journey not just into the perils of a star-forming nebula, but into confrontation with a billion-year-old adversary of life as they know it. Whatever chance they have of stopping the terrifying Mindaru may be found only in the fiery heart of an intelligent sun. Meanwhile, back on Triton, Julie Stone experiences her own encounter with the translator, and she too must make a life-or-death decision in defense of the Earth. Sunborn is Volume 4 of The Chaos Chronicles from the Nebula-nominated author of Eternity's End. Includes an Afterword by the author. DRM-free. REVIEWS: “Carver does his usual outstanding job of juggling multiple viewpoints and plot threads while casting his protagonists’ adventures against a sweeping, intergalactic backdrop. Yet Bandicut’s story is ultimately a very human one about determination, seat-of-the-pants ingenuity, and courage in the face of overwhelming danger.” —Booklist “Space opera at its most agreeably and classically science fictional... Carver skillfully rotates viewpoints and weaves the choreography directly into the plot.” —Publishers Weekly “Leaps quite madly from pot to kettle to frying pan to fire. The pace never lets up...[a] remarkably expansive vision.” —Analog “Carver’s latest addition to the “Chaos Chronicles”... ensures his place among the most inventive of contemporary authors of hard sf and speculative theory. Filled with startling ideas and ingenious plot twists, this sf adventure (along with its series predecessors) belongs in most sf collections. —Library Journal
