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.

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.

Dark Stars, edited by John F.D. Taff, is a tribute to horror’s longstanding short fiction legacy, featuring 12 terrifying original stories from today's most noteworthy authors. Within these pages you’ll find tales of dead men walking, an insidious secret summer fling, an island harboring unspeakable power, and a dark hallway that beckons. You’ll encounter terrible monsters—both human and supernatural—and be forever changed. The stories in Dark Stars run the gamut from traditional to modern, from dark fantasy to neo-noir, from explorations of beloved horror tropes to the unknown—possibly unknowable—threats. It’s all in here because it’s all out there, now, in horror. Dark Stars features all-new stories from the following award-winning authors and up-and-coming voices: Chesya Burke, Ramsey Campbell, Gemma Files, Stephen Graham Jones, Alma Katsu, Caroline Kepnes, John Langan, Livia Llewellyn, Josh Malerman, Usman T. Malik, Priya Sharma, and John F.D. Taff. Created as an homage to the 1980 classic horror anthology Dark Forces, edited by Kirby McCauley, Dark Stars features an afterword from original contributor Ramsey Campbell—a poignant finale to this bone-chilling collection.

United States Lighthouse Society photographer David Zapatka travels to 17 states capturing historic beacons from when they have always been meant to be seen: at night, under glorious star-filled skies. Follow David on his journeys as he recounts the perils of visiting unfamiliar locations deep into the night: marvel at the wonderful historic architecture of our nation's lighthouses; and learn the fascinating history of more than 160 beautiful towers.This followup to Stars & Lights: Darkest of Dark Nights, is David's second photography coffee table book, and is a perfect compliment as he presents dozens of unique lighthouse images never before published. Now a collaboration with the United States Lighthouse Society, the photographs are presented as individual portraits followed by tales of nighttime adventures.

Astronomers have successfully observed a great deal of the Universe's history, from recording the afterglow of the Big Bang to imaging thousands of galaxies, and even to visualising an actual black hole. There's a lot for astronomers to be smug about. But when it comes to understanding how the Universe began and grew up we are literally in the dark ages. In effect, we are missing the first one billion years from the timeline of the Universe. This brief but far-reaching period in the Universe's history, known to astrophysicists as the 'Epoch of Reionisation', represents the start of the cosmos as we experience it today. The time when the very first stars burst into life, when darkness gave way to light. After hundreds of millions of years of dark, uneventful expansion, one by the one these stars suddenly came into being. This was the point at which the chaos of the Big Bang first began to yield to the order of galaxies, black holes and stars, kick-starting the pathway to planets, to comets, to moons, and to life itself. Incorporating the very latest research into this branch of astrophysics, this book sheds light on this time of darkness, telling the story of these first stars, hundreds of times the size of the Sun and a million times brighter, lonely giants that lived fast and died young in powerful explosions that seeded the Universe with the heavy elements that we are made of. Emma Chapman tells us how these stars formed, why they were so unusual, and what they can teach us about the Universe today. She also offers a first-hand look at the immense telescopes about to come on line to peer into the past, searching for the echoes and footprints of these stars, to take this period in the Universe's history from the realm of theoretical physics towards the wonder of observational astronomy.

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.
