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.

From the internationally bestselling author of Love Her Wild comes The Dark Between Stars, a new illustrated collection of heartfelt, whimsical, and romantic poems from Instagram poetry sensation, Atticus. Atticus, has captured the hearts and minds of nearly 700k followers (including stars like Karlie Kloss, Emma Roberts, and Alicia Keys). In his second collection of poetry, The Dark Between Stars, he turns his attention to the dualities of our lived experiences—the inescapable connections between our highest highs and lowest lows. He captures the infectious energy of starting a relationship, the tumultuous realities of commitment, and the agonizing nostalgia of being alone again. While grappling with the question of how to live with purpose and find meaning in the journey, these poems offer both honest explorations of loneliness and our search for connection, as well as light-hearted, humorous observations. As Atticus writes poignantly about dancing, Paris, jazz clubs, sunsets, sharing a bottle of wine on the river, rainy days, creating, and destroying, he illustrates that we need moments of both beauty and pain—the darkness and the stars—to fully appreciate all that life and love have to offer.

Light Is the New Black is for those who agreed to be here at this time in history to answer the call of their soul and work their light. Rebecca Campbell had her first awakening when she was a teenager, but without anyone to guide her, she ignored her soul's callings and dimmed her light in order to fit in. Then, just before her 30th birthday, the life she had so consciously created began to crumble around her. It was as if the Universe had turned off all the lights, so she had no choice but to rediscover her own. In this inspirational book, Rebecca shares her own healing journey, alongside practical tools to help you reconnect with the core of your being, and channelled messages from the Universe. Once you rediscover what you already know at soul level, you can create a life that is in divine alignment, discover your soul gifts, and offer the world something that only you can give. “When I first woke up to the callings of my soul, I lacked the courage, confidence, inner support, and practical tools not just to hear the callings of my soul, but to let them truly lead my life. There were pieces missing, a journey needed to be taken. I called upon the Universe and spiritual teachers to support me. This book is the result of that journey. You can read it in one sitting, one chapter a day, or pick a page at random for an instant hit of guidance. Throughout you will find ‘Work Your Light’ exercises, mantras, and affirmations. I created these with the intention of guiding you not only to hear the callings of your soul, but to act on them too... I pray that you discover the authentic gift to the world that you already are and choose to serve the world by being You. Follow what lights you up and you will light up the world. So much love, Rebecca x

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."

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.
