Book Description
There has been very considerable progress in research into low-mass stars, brown dwarfs and extrasolar planets during the past few years, particularly since the fist edtion of this book was published in 2000. In this new edtion the authors present a comprehensive review of both the astrophysical nature of individual red dwarf and brown dwarf stars and their collective statistical properties as an important Galactic stellar population. Chapters dealing with the observational properies of low-mass dwarfs, the stellar mass function and extrasolar planets have been completely revised. Other chapters have been significantly revised and updated as appropriate, including important new material on observational techniques, stellar acivity, the Galactic halo and field star surveys. The authors detail the many discoveries of new brown dwarfs and extrasolar planets made since publication of the first edition of the book and provide a state-of-the-art review of our current knowledge of very low-mass stars, brown dwarfs and extrasolar planets, including both the latest observational results and theoretical work.

Book Description
Perhaps the most common question that a child asks when he or she sees the night sky from a dark site for the first time is: 'How many stars are there?' This happens to be a question which has exercised the intellectual skills of many astronomers over the course of most of the last century, including, for the last two decades, one of the authors of this text. Until recently, the most accurate answer was 'We are not certain, but there is a good chance that almost all of them are M dwarfs. ' Within the last three years, results from new sky-surveys - particularly the first deep surveys at near infrared wavelengths - have provided a breakthrough in this subject, solidifying our census of the lowest-mass stars and identifying large numbers of the hitherto almost mythical substellar-mass brown dwarfs. These extremely low-luminosity objects are the central subjects of this book, and the subtitle should be interpreted accordingly. The expression 'low-mass stars' carries a wide range of meanings in the astronomical literature, but is most frequently taken to refer to objects with masses comparable with that of the Sun - F and G dwarfs, and their red giant descendants. While this definition is eminently reasonable for the average extragalactic astronomer, our discussion centres on M dwarfs, with masses of no more than 60% that of the Sun, and extends to 'failed stars' - objects with insufficient mass to ignite central hydrogen fusion.

Book Description
NEW YORK TIMES BESTSELLER • GOOD MORNING AMERICA BUZZ PICK • “A total departure for the author of The Paris Wife, McLain’s emotionally intense and exceptionally well-written thriller entwines its fictional crime with real cases.”—People (Book of the Week) NAMED ONE OF THE BEST BOOKS OF THE YEAR BY MARIE CLAIRE • “The kind of heart-pounding conclusion that thriller fans crave . . . In the end, a book full of darkness lands with a message of hope.”—The New York Times Book Review “This mystery will keep you guessing, and stay with you long after you finish. Dive in.”—Daily Skimm Anna Hart is a seasoned missing persons detective in San Francisco with far too much knowledge of the darkest side of human nature. When tragedy strikes her personal life, Anna, desperate and numb, flees to the Northern California village of Mendocino to grieve. She lived there as a child with her beloved foster parents, and now she believes it might be the only place left for her. Yet the day she arrives, she learns that a local teenage girl has gone missing. The crime feels frighteningly reminiscent of the most crucial time in Anna’s childhood, when the unsolved murder of a young girl touched Mendocino and changed the community forever. As past and present collide, Anna realizes that she has been led to this moment. The most difficult lessons of her life have given her insight into how victims come into contact with violent predators. As Anna becomes obsessed with saving the missing girl, she must accept that true courage means getting out of her own way and learning to let others in. Weaving together actual cases of missing persons, trauma theory, and a hint of the metaphysical, this propulsive and deeply affecting novel tells a story of fate, necessary redemption, and what it takes, when the worst happens, to reclaim our lives—and our faith in one another.

Book Description
Tom Van Flandern's book adds a new dimension to cosmology--not only does it present a novel approach to timeless issues, it stands up to the closest scientific scrutiny. Even the most respected scientists today will readily admit that the Big Bang Theory is full of holes. But it takes a new look, like Dark Matter, Missing Planets, and New Comets, to explain not only why the theory is wrong but what to substitute in its place. If you are curious about such things as the nature of matter and the origin of the solar system, but feel inadequately equipped to grasp what modern science has to say about such things, read this book. You will not get the all too common condescending attempt to water down the `mysteries' of modern science into a form intelligible to little non scientist you, but rather a straightforward new theory, logically derived in front of your eyes, which challenges the roots of many of today's complex accepted paradigms, yet whose essence is simple enough to be thoroughly communicated to the intelligent layman without "losing it in the translation."

Book Description
The Drakh have assaulted Earth with deadly Shadow technology -- but the worst is yet to come in this stunning continuation of the Babylon 5 epic adventure... Centauri Prime has been infiltrated by malevolent allies of the Shadows, creatures known as the Drakh. While Centauri citizens continue to rebuild their war-torn planet, their secret masters work feverishly toward one ultimate goal: to crush the Interstellar Alliance once and for all. As the Drakh carry out their horrific plans, Emperor Londo Mollari languishes on his throne, a puppet of the Drakh-bred keeper, an insidious creature that monitors his every thought, word, and action. While the emperor broods, the power-obsessed Lord Durla -- an unwitting Drakh pawn -- follows his own agenda. But Drakh control is not absolute. Vir Cotto -- a most unlikely hero -- has begun a resistance movement, and Alliance President John Sheridan has sent his most trusted troubleshooter, Michael Garibaldi, to investigate. Yet this move may prove costly, and though the Centauri continue to build a new military machine, the Alliance avoids any overt confrontation, hoping the problem will go away. They're about to discover how wrong they are...
