Astrophysics of Black Holes: From Fundamental Aspects to Latest Developments (Astrophysics and Space Science Library #440)
by Cosimo BambiThis book discusses the state of the art of the basic theoretical and observational topics related to black hole astrophysics. It covers all the main topics in this wide field, from the theory of accretion disks and formation mechanisms of jet and outflows, to their observed electromagnetic spectrum, and attempts to measure the spin of these objects. Black holes are one of the most fascinating predictions of general relativity and are currently a very hot topic in both physics and astrophysics. In the last five years there have been significant advances in our understanding of these systems, and in the next five years it should become possible to use them to test fundamental physics, in particular to predict the general relativity in the strong field regime. The book is both a reference work for researchers and a textbook for graduate students.
Astrophysics of Exoplanetary Atmospheres: 2nd Advanced School on Exoplanetary Science (Astrophysics and Space Science Library #450)
by Valerio Bozza Luigi Mancini Alessandro SozzettiIn this book, renowned scientists describe the complexity of exoplanetary atmospheres and all of the observational techniques that are employed to probe them. Readers will also find a panoramic description of the atmospheres of the planets within the Solar System, with explanation of considerations especially relevant to exoplanets. Over the past few years, thousands of exoplanets have been discovered orbiting around stars relatively close to the Solar System. Astronomers have revealed how varied these exoplanets are (rocky, icy, giant) and how diverse their architecture can be, confirming science fiction images in several cases and extending beyond the human imagination in others. The natural next step is to study their atmospheres and to understand their chemical composition and the physical processes taking place in their interiors, with the aim of detecting biomarkers. This book will appeal to all who seek a comprehensive, state-of-the-art account of the latest knowledge in the rapidly developing and highly interdisciplinary field of exoplanet research.
Astrophysics of Planet Formation
by Philip J. ArmitageConcise and self-contained, this textbook gives a graduate-level introduction to the physical processes that shape planetary systems, covering all stages of planet formation. Writing for readers with undergraduate backgrounds in physics, astronomy, and planetary science, Armitage begins with a description of the structure and evolution of protoplanetary disks, moves on to the formation of planetesimals, rocky, and giant planets, and concludes by describing the gravitational and gas dynamical evolution of planetary systems. He provides a self-contained account of the modern theory of planet formation and, for more advanced readers, carefully selected references to the research literature, noting areas where research is ongoing. The second edition has been thoroughly revised to include observational results from NASA's Kepler mission, ALMA observations and the JUNO mission to Jupiter, new theoretical ideas including pebble accretion, and an up-to-date understanding in areas such as disk evolution and planet migration.
Astrophysics of the Interstellar Medium
by Walter J. MacielThe space between the stars contains a large diversity of objects in which physical processes occur that are fundamental to the structure and evolution of galaxies. This book offers the reader a basic knowledge of these processes and presents simple numeric estimates of the main quantities relevant to the interstellar medium. The main objects that constitute the interstellar space are described, but the emphasis of the book lies in the physical processes occurring in these objects, which may also occur in other astrophysical environments. The book is directed tor graduate as well as advanced undergraduate students of physics and astrophysics.
Astrophysics of the Interstellar Medium (UNITEXT for Physics)
by Giovanni CarraroThis book is based on a series of lectures for an Astrophysics of the Interstellar Medium (ISM) master’s degree in Astrophysics and Cosmology at Padova University. From the cold molecular phase in which stars and planetary systems form, to the very hot coronal gas that surrounds galaxies and galaxy clusters, the ISM is everywhere. Studying its properties is vital for the exploration of virtually any field in astronomy and cosmology. These notes give the student a coherent and accurate mathematical and physical approach, with continuous references to the real ISM in galaxies. The book is divided into three parts. Part One introduces the equations of fluid dynamics for a system at rest and acoustic waves, and then explores the real ISM through the role of thermal conduction and viscosity, concluding with a discussion of shock waves and turbulence. In Part Two, the electromagnetic field is switched on and its role in modulating shock waves and contrasting gravity is studied. Part Three describes dust and its properties, followed by the main stellar sources of energy. The last two chapters respectively address the various components of the ISM and molecular clouds and star formation.
Astrophysics with Radioactive Isotopes (Astrophysics and Space Science Library #453)
by Nikos Prantzos Roland Diehl Dieter H. HartmannDealing with astrophysics derived from the radiation emitted by radioactive atomic nuclei, this book describes the different methods used to measure cosmic radio-isotopes. It demonstrates how this astronomical window has contributed to the understanding of the sources and the chemical evolution of cosmic gas. Reference materials and explanations are included for students in advanced stages of their education.Nuclear reactions in different sites across the universe lead to the production of stable and unstable nuclei. Their abundances can be measured through different methods, allowing to study the various nuclear processes taking place in cosmic environments. Nucleosynthesis is the cosmic formation of new nuclear species, starting from hydrogen and helium resulting from the big bang origins. Stars create and eject synthesized nuclei during their evolution and explosions. Incorporation of the new interstellar composition into next-generation stars characterises the compositional (chemical) evolution of cosmic gas in and between galaxies. Radioactive species have unique messages about how this occurs. Since the first Edition of this book published in 2011 with the title Astronomy with Radioactivities, long-awaited new direct observations of supernova radioactivity have been made and are now addressed in two updated chapters dealing with supernovae. In this second Edition, the advances of recent years beyond one-dimensional treatments of stellar structure and stellar explosions towards 3-dimensional models have been included, and led to significant re-writings in Chapters 3-5. The sections on the Solar System origins have been re-written to account for new insights into the evolution of giant molecular clouds. The chapter on diffuse radioactivities now also includes material measurements of radioactivities in the current solar system, and their interpretations for recent nucleosynthesis activity in our Galaxy. Significant new results on gamma-rays from positron annihilations have been accounted for in that chapter, and led to new links with nucleosynthesis sources as well as interstellar transport processes. A new chapter now provides a description of interstellar processes often called 'chemical evolution', thus linking the creation of new nuclei to their abundance observations in gas and stars. The experimental / instrumental chapters on nuclear reaction measurements, on gamma-ray telescopes, and pre-solar grain laboratories have been updated. Moreover, new windows of astronomy that have been opened up in recent years have been included in the discussions of the multi-messenger approach that broadens the basis for astrophysical insights.

Astrotopia: The Dangerous Religion of the Corporate Space Race
by Mary-Jane RubensteinA revealing look at the parallel mythologies behind the colonization of Earth and space—and a bold vision for a more equitable, responsible future both on and beyond our planet. As environmental, political, and public health crises multiply on Earth, we are also at the dawn of a new space race in which governments team up with celebrity billionaires to exploit the cosmos for human gain. The best-known of these pioneers are selling different visions of the future: while Elon Musk and SpaceX seek to establish a human presence on Mars, Jeff Bezos and Blue Origin work toward moving millions of earthlings into rotating near-Earth habitats. Despite these distinctions, these two billionaires share a core utopian project: the salvation of humanity through the exploitation of space. In Astrotopia, philosopher of science and religion Mary-Jane Rubenstein pulls back the curtain on the not-so-new myths these space barons are peddling, like growth without limit, energy without guilt, and salvation in a brand-new world. As Rubenstein reveals, we have already seen the destructive effects of this frontier zealotry in the centuries-long history of European colonialism. Much like the imperial project on Earth, this renewed effort to conquer space is presented as a religious calling: in the face of a coming apocalypse, some very wealthy messiahs are offering an other-worldly escape to a chosen few. But Rubenstein does more than expose the values of capitalist technoscience as the product of bad mythologies. She offers a vision of exploring space without reproducing the atrocities of earthly colonialism, encouraging us to find and even make stories that put cosmic caretaking over profiteering.
Astrotwins -- Project Blastoff
by Martha Freeman Mark KellyA team of middle schoolers prepares for blastoff in this adventure from the author of the New York Times bestselling Mousetronaut, based on the childhoods of real-life astronauts Mark Kelly and his twin brother Scott.It's a long, hot summer and Scott and Mark are in big trouble for taking apart (aka destroying) their dad's calculator. As a punishment, they're sent to their grandfather's house, where there's no TV and they have to do chores. And Grandpa is less tolerant of the twins' constant bickering. "Why don't you two work together on something constructive. What if you built a go-kart or something?" Grandpa suggests. But it's not a go-kart the twins are interested in. They want to build a rocket. With the help of Jenny, nicknamed Egg, and a crew of can-do kids, they set out to build a real rocket that will blast off and orbit the Earth. The question soon becomes: which twin will get to be the astronaut? Written by a NASA astronaut with four space flights under his belt, this exciting story includes extensive back matter on the space program with fantastic facts and details.
Astrotwins -- Project Rescue
by Martha Freeman Mark KellyTwins Mark and Scott discover an abandoned Apollo command module and take off to rescue a stranded Russian cosmonaut in the second Astrotwins adventure from retired NASA astronaut and the #1 New York Times bestselling author of Mousetronaut, Mark Kelly.Mark and Scott Kelly, who are mostly known for getting in trouble, are finally back from their first space adventure. The twins have wanted to explore space ever since they were little and watched Neil Armstrong walk on the moon. And when they hear that a Russian cosmonaut is trapped inside the Salyut space station now orbiting 220 miles above the surface of the Earth, they wish they could find a way to help. While staying in the countryside at their grandfather's house with their friend Jenny (aka Egg), the twins repurpose a NASA Titan 2 rocket ship being stored nearby. Complete with spacesuits and snacks, the twins take off to rescue the Russian spacecraft. Will they ever see their family or their grandfather's backyard again? Written by a NASA astronaut with four space flights under his belt, the second exciting Astrotwins story includes extensive back matter on the space program with fantastic facts and details.
Astrovirus Research: Essential Ideas, Everyday Impacts, Future Directions
by Stacey Schultz-CherryAstroviruses were first identified in the feces of children in 1975. Since then, they have been found in ~ 3 to 20% of children with diarrhea. Given that serological studies have demonstrated that up to 90% of children have been exposed to at least one strain of astrovirus by age 9, the prevalence of infection may be much higher. Supporting this are studies demonstrating that astroviruses can also be isolated in a subset of asymptomatic individuals, suggesting that a proportion of infected individuals shed the virus asymptomatically or for some time after the resolution of other symptoms of infection. Asymptomatic carriers may be a major reservoir for astroviruses in the environment and could contribute to dissemination of the virus. Astroviruses are extremely stable in the environment and can be transmitted nosocomially, directly from infected individuals and potentially animals, and through contaminated food and water. Although typically an acute disease, astrovirus infection in premature infants may be associated with the development of necrotizing enterocolitis and in new-onset celiac disease in children. Immunocompromised children are even more susceptible often developing persistent infections that lead to wasting or even systemic infections associated with fatal encephalitis. In spite of its importance, little is known about astrovirus pathogenesis, molecular biology, epidemiology, or cell biology. The goal of this book is to provide the latest and most up-to-date information on this medically important and rapidly evolving group of viruses. It will include sections on the history of astroviruses and their disease in humans; information on viral replication and immune responses; new information on how astroviruses induce disease including the expression of a viral enterotoxin regulating intestinal epithelial cell tight junctions, the isolation and identification of new astrovirus genotypes in mammals including humans, and astroviruses of veterinary importance. Finally, the book will also introduce the complexity of astrovirus epidemiology and potential as an important new zoonotic disease, and its role in food-borne disease. This will be the first book of its kind and will be of great interest to microbiologists, virologists, infectious disease specialists, immunologists, pediatricians, public health and food safety experts, veterinarians, poultry industry specialists, and researchers and clinicians interested in enteritis.
Aswan High Dam Resettlement of Egyptian Nubians (SpringerBriefs on Case Studies of Sustainable Development)
by Thayer ScudderThis book highlights the long-term resettlement process of the Egyptian Nubian people along the Aswan High Dam. Assessing the resettlement of 48,000 Egyptian Nubians in connection with the High Dam is especially important for three main reasons: firstly, this resettlement process is one of the rare cases in which research begun before the dam was built has continued for over forty years. Secondly, the resettlement of the Egyptian Nubian people is one of the few cases in which the living standards of the large majority improved because of the initial political will of the government, combined with Nubian initiatives. Thirdly, given the complexity of the resettlement process, weaknesses in government planning, implementation, and in the weakening of government political provide valuable lessons for future dam-induced resettlement efforts.

Asymmetric Catalysis on Industrial Scale: Challenges, Approaches and Solutions
by Hans-Ulrich Blaser et al.This second edition of the pioneering work on this hot topic captures the major trends and latest achievements in the art of asymmetric catalysis on an industrial scale. A number of completely new real-life case studies written by the world leaders in their respective areas provide a compact and qualified insight into this developing field. The resulting ready reference and handbook collates first-hand and valuable information within a context where it can be easily found. The high-quality contributions illustrate the relevant environments and situations, such as time pressure, how the catalytic step fits into the overall synthesis, or competition with other synthetic approaches, as well as the typical problems encountered in the various phases, including finding/developing the catalyst and optimization of the process or choice of equipment. Both successful and unsuccessful approaches to solve these problems are described.
Asymmetric Cell Division in Development, Differentiation and Cancer (Results and Problems in Cell Differentiation #61)
by Jacek Z. Kubiak Jean-Pierre TassanThis book provides readers with an overview of the frequent occurrence of asymmetric cell division. Employing a broad range of examples, it highlights how this mode of cell division constitutes the basis of multicellular organism development and how its misregulation can lead to cancer. To underline such developmental correlations, readers will for example gain insights into stem cell fate and tumor growth. In turn, subsequent chapters include descriptions of asymmetric cell division from unicellular organisms to humans in both physiological and pathological conditions. The book also illustrates the importance of this process for evolution and our need to understand the background mechanisms, offering a valuable guide not only for students in the field of developmental biology but also for experienced researchers from neighboring fields.
Asymmetric Continuum: Extreme Processes in Solids and Fluids (GeoPlanet: Earth and Planetary Sciences #3)
by Roman Teisseyre Maria Teisseyre-JeleńskaThis book deals with a class of basic deformations in Asymmetric Continuum Theory. It describes molecular deformations and transport velocities in fluids, strain deformations in solids as well as the molecular transport, important in fracture processes. In solids, a separate problem relates to the displacements; their recording, e. g. , by means of the seismometers, proves only the existence of the displacement derivatives and not a real displacement. However, the molecular displacements and new fracture criterion including the defect distributions and induced strains are defined in the book too. In fluids, the transport velocities and molecular strains describe the motion processes. The vortex motions are defined by means of the rotational transport; this approach leads to more complicated problems, like the turbulence phenomena. The interaction processes, including the electric and magnetic fields, and some thermodynamical problems and quantum theory analogies help to understand the extreme processes
Asymmetric Dearomatization Reactions
by Shu-Li YouThe first comprehensive account of the rapidly growing field of asymmetric dearomatization reactions with a focus on catalytic methods.

Chapters on dearomatizations of electron-deficient aromatic rings, dearomatization reactions via transition metal-catalyzed cross-couplings as well as dearomatization strategies in the synthesis of complex natural products are also included. Written by pioneers in the field, this is a highly valuable source of information not only for professional synthetic chemists in academia and industry but also for all those are interested in asymmetric methodologies and organic synthesis in general.
Asymmetric Dual Core Waveguides: Dynamics of Self-Similar Waves (Progress in Optical Science and Photonics #22)
by Soloman Raju ThokalaThis book highlights the dynamical behavior of self-similar waves in asymmetric dual-core waveguides. The proposed dual-core waveguide consists of two closely spaced adjoining fibers in which one fiber is active and the other is passive. Due to the linear coupling between them, the dynamics of the wave propagating through the passive core can be controlled by manipulating the dynamics of the wave propagating in the active core. The optimal pulse compression or amplification of these waves as the length of the fiber tends to infinity is presented. The exact Mobius transform self-similar solutions that propagate through these waveguides self-similarly are subject to simple scaling rules. The book includes experiments conducted to corroborate the analytical predictions.
