Theory of Orbits treats celestial mechanics as well as stellar dynamics from the common point of view of orbit theory, making use of concepts and techniques from modern geometric mechanics. It starts with elementary Newtonian mechanics and ends with the dynamics of chaotic motion. The two volumes are meant for students in astronomy and physics alike. Prerequisite is a physicist's knowledge of calculus and differential geometry.

This book characterizes the kinematic and chemical structures of disk-forming regions around low-mass protostellar sources and their interplay based on Atacama Large Millimeter/submillimeter Array (ALMA) observations. It describes the chemical evolution of molecules formed in an interstellar gas using the ALMA observations of 5 Sun-like protostars at a spatial resolution of a few tens au scale, which unveils the physical mechanism of star and planetary formation. The book reviews the author's successful works, focusing on two key findings: (i) A drastic change in the chemical composition of the gas around the centrifugal barrier of the infalling-rotating envelopes, and (ii) the chemical composition in the disk-forming regions, which varies from source to source depending on the chemical characteristics of the parent molecular cloud. These findings are based on the fine characterization of physical structures based on careful kinematic analyses. An additional attraction is the inclusion of the skillful reviews of ALMA observatory and its observation and physical models to describe the observed gas structure.

As a result of significant research over the past 20 years, black holes are now linked to some of the most spectacular and exciting phenomena in the Universe, ranging in size from those that have the same mass as stars to the super-massive objects that lie at the heart of most galaxies, including our own Milky Way. This book first introduces the properties of simple isolated holes, then adds in complications like rotation, accretion, radiation, and magnetic fields, finally arriving at a basic understanding of how these immense engines work.

Black Hole Astrophysics

reviews our current knowledge of cosmic black holes and how they generate the most powerful observed pheonomena in the Universe;

highlights the latest, most up-to-date theories and discoveries in this very active area of astrophysical research;

The book begins at the Sun then travels through the solar system to see the stars, how they work, and ultimately what they mean to us. The idea is to provide an integrated view of the galaxy and its contents. Along the way we look at spectra, atmospheric phenomena, gravity and the laws of motion, telescopes and how they work, interstellar gas and dust, star birth and death, and planets orbiting other stars. Most popular books tend to focus on one particular topic. From the Sun to the Stars is one of the few that tells the story of the Sun against the background of other stars and other planets and, for that matter, of stars and other planets against the background of the Sun and solar system. This presents the subject with a breadth that few other books can match.This book grew out of the OLLI (Osher Lifelong Learning Institute) lectures given by the author at the University of Illinois. It doesn't require any prior knowledge and is suitable for anyone who is interested in astronomy.

The Spatialities of Radio Astronomy examines the multidisciplinary overlap between the spatial disciplines and the studies of science and technology through a comparative study of four of the world’s most important radio telescopes. Employing detailed analysis, historical research, interviews, personal observations, and various conceptual manoeuvres, Guy Trangoš reveals the depth of spatial process active at these scientific sites and the territories they traverse. Through the conceptual frameworks of territory, hyper-concentration, and contingency, Trangoš interprets the telescope as exploded across space and time, present in multiple connected sites simultaneously, and active in the production of space. He develops a historiographic and contemporary analysis of the Atacama Large Millimeter/submillimeter Array (ALMA, Chile); the Five-hundred-meter Aperture Spherical radio Telescope (FAST, China); the Arecibo Observatory (Puerto Rico); and the MeerKAT/SKA (South Africa). These case studies are global exemplars of the different spatial transformations that occur through science. Their relationships to surrounding communities and landscapes reveal deeper constitutional processes embodied in each institutional and spatial form. This book spans the modern history of architecture and science, the studies of science, technology and society, and urban theory. It is of specific interest to architects and designers expanding their analysis of spatial production, scholars in the study of geography, landscape, science, technology, and astronomy, and people fascinated with how these radio telescopes were conceptualised, built, and operate today.

The aim of this book is to teach undergraduate college or university students, and adults interested in astronomy and astrophysics, the basic mathematics and physics concepts needed to understand the evolution of the universe, and based on this to teach the astrophysical theories behind evolution from the very early times to the present. The book does not require extensive knowledge of mathematics, like calculus, and includes material that explains concepts such as velocity, acceleration, and force. Based on this, fascinating topics such as Dark Matter, measuring Dark Energy via supernovae velocities, and the creation of mass via the Higgs mechanism are explained. All college students with an interest in science, especially astronomy, without extensive mathematical backgrounds, should be able to use and learn from this book. Adults interested in topics like Dark Energy, the Higgs boson, and detection of Gravitational Waves, which are in the news, can make use of this book as well.

Presenting a novel theory spanning many different fields in physics, the key concepts in each field are introduced.The reader is only expected to know the rudiments of condensed matter physics, quantum field theory and general relativity to explore this fascinating new model of dark matter and dark energy as facets of a cosmic superfluid.

An almost complete collection of the papers given at the International Workshop on Imaging in High Energy Astronomy (Anacapri, Italy, 1994). These proceedings, which concentrate on imaging above 10 keV, represent the state of the art in the field, resulting from the success of many missions (I.C. Granat and CGRO) carrying detectors for high energy astronomy with imaging capabilities. The main topics of the book are Bragg concentrators, coded mask-modulation collimators, double Compton telescopes, the occultation method, tracking chambers, and new experimental techniques. The book also contains some papers dealing with image reconstruction and processing, with an emphasis on the above techniques.

The reader will find in this volume the Proceedings of the NATO Advanced Study Institute held in Cortina d'Ampezzo, Italy between August 3 and August 13, 1987 under the title "Long Term Dynamical Behaviour of Natural and Artificial N-body Systems." The Institute was the latest in a series held in 1972, 1975, 1978, 1981, 1984 in dynamical astronomy, theoretical mechanics and celestial mechanics under the Directorship of Professor Victor Szebehely. These previous institutes, held in high esteem by the international community of research workers, have resulted in a series of well-received and valuable Proceedings. In correspondence with Professor Szebehely and in long discussions with him in Colorado in August 1985, I agreed to his request that I undertake the preparation of a new ASI. I was happy to do so knowing I could call upon his vast experience in overseeing such ASI's. The last quarter century has been a period in which increasingly rapid progress has been made in celestial mechanics and related subjects not only because of the appearance of new problems urgently requiring solution but also because of the advent of new analytical techniques and powerful computer hardware and software.

There are very few with Philip Morrison's gifts, few who can lead us with firm knowledge whispering just the right encouragement as he guides us across the great ideas of science. Take this journey with one of the most astute navigators and you'll find yourself compelled to go deeper into some of the most daring adventures of modern science. Nothing is too grand or seemingly too trivial - the nature of time, the fabric of the atom, what it means to explore scientific horizons, the galaxies, even the search for unknown intelligence in the vast as-yet-uncharted universe. Then as deftly as Morrison takes us on a dazzling tour of the stars, he gently settles down for an intimate stop in the nursery where children have their first encounters with the things of everyday life, everyday things that cause us to wonder and make for discovery. With an equally firm grasp, Morrison, who witnessed the first tests of the atom bomb, takes us unflinchingly through some of the most frightening terrain of modern times, where the arms race can cause our ultimate destruction, but where sanity can still bring us peace. This extraordinary collection of essays by one of the most profound commentators on the successes and failures of the scientific enterprize concludes with lively portraits of men of science - Neils Bohr, Richard Feynman, Charles Babbage, among other notable friends and heroes.

This volume collects the contributions to the 10th European Workshop on White Dwarfs held in Blanes, Spain, in June 1996.

This text provides a snapshot of current understanding of the origin, structure and evolution of white dwarf stars from both the theoretical and the observational points of view. It also takes into account the properties of white dwarfs as members of binary systems, stellar clusters and galactic populations.

Ever since 1911, the Solvay Conferences have shaped modern physics. The format is quite different from other conferences as the emphasis is placed on discussion. The 26th edition held in October 2014 in Brussels and chaired by Roger Blandford continued this tradition and addressed some of the most pressing open questions in the fields of astrophysics and cosmology, gathering many of the leading figures working on a wide variety of profound problems.The proceedings contain the 'rapporteur talks' giving a broad overview with unique insights by distinguished renowned scientists. These lectures cover the five sessions: 'Neutron Stars', 'Black Holes', 'Cosmic Dawn', 'Dark Matter' and 'Cosmic Microwave Background'.In the Solvay tradition, the proceedings also include the prepared comments to the rapporteur talks. The discussions among the participants - expert, yet lively and sometimes contentious - have been edited to retain to retain their flavor and are reproduced in full. The reader is taken on a breathtaking ride through 42 years of extraordinary discovery since astrophysics was last on the Solvay program and 57 years since cosmology was last discussed.

In this fascinating foray into the millennia-long relationship between science and military power, acclaimed astrophysicist and "the world's best science communicator" (Times Literary Supplement) Neil deGrasse Tyson and writer-researcher Avis Lang examine how the methods and tools of astrophysics have been enlisted in the service of war. "The overlap is strong, and the knowledge flows in both directions", say the authors, because astrophysicists and military planners care about many of the same things: multi-spectral detection, ranging, tracking, imaging, high ground, nuclear fusion and access to space. Tyson and Lang call it a "curiously complicit" alliance. "The universe is both the ultimate frontier and the highest of high grounds", they write. "Shared by both space scientists and space warriors, it's a laboratory for one and a battlefield for the other. The explorer wants to understand it; the soldier wants to dominate it. But without the right technology-which is more or less the same technology for both parties-nobody can get to it, operate in it, scrutinise it, dominate it or use it to their advantage and someone else's disadvantage." Spanning early celestial navigation to satellite-enabled warfare, Accessory to War is a richly researched and provocative examination of the intersection of science, technology, industry and power that will introduce Tyson's millions of fans to yet another dimension of how the universe has shaped our lives and our world.

This thesis develops the dispersive optical model into a tool that allows for the assessment of the validity of nuclear reaction models, thereby generating unambiguous removal probabilities of nucleons from valence orbits using the electron-induced proton knockout reaction. These removal probabilities document the substantial quantitative degree in which nuclei deviate from the independent-particle model description. Another outcome reported within is the prediction for the neutron distribution of Ca-40, Ca-48, and Pb-208. The neutron radii of these nuclei have direct relevance for the understanding of neutron stars and are currently the subject of delicate experiments. Unlike other approaches, the current method is consistent with all other relevant data and describes nuclei beyond the independent-particle model. Finally, a new interpretation of the saturation probabilities of infinite nuclear matter is proposed suggesting that the semi-empirical mass formula must be supplemented with a better extrapolation from nuclei to infinite matter.

"The dominant figures of postwar astrophysical cosmology have been the late Yakov Ze'ldovich, of Moscow, and Jim Peebles, of Princeton. But running a close third in influence has been Joseph Silk.... This collection is essential reading for the cosmological enthusiast." Nature These essays represent Joseph Silk's own meandering around cosmic themes. The topics span the beginning of time until its end and encompass the enigma of the evolution of large-scale structure, culminating in the formation of the galaxies. Dr. Silk has taken these writings from pieces written over the years, many commissioned to highlight a new look at a new discovery in cosmology. Some have been rewritten to capture a modern perspective while others remain as written to encapsulate his thoughts of a decade ago.

Today many scientists recognize plasma as the key element in understanding new observations in interplanetary and interstellar space, in stars, galaxies, and clusters of galaxies, and throughout the observable universe. Plasma astrophysics and cosmology, as a unified discipline, cover topics such as the large-scale structure and filamentation of the universe; the microwave background; the formation of galaxies and magnetic fields; active galactic nuclei and quasars; the origin and abundance of light elements; star formation and the evolution of solar systems; redshift periodicities and anomalous redshifts; general relativity; electric fields; the acceleration of charged particles to high energies; and cosmic rays. This text provides an update on the observations made in radio, optical and high-energy astrophysics, especially since 1985, and addresses the paradigm changing discoveries made by the planetary probes and satellites, radio telescopes, and the Hubble space telescope. Over 20 contributors, all distinguished plasma scientists, present a picture of the nature of our plasma universe with articles ranging from the popular level to advanced topics in plasma cosmology.

Unified Field Mechanics, the topic of the 9th international symposium honoring noted French mathematical physicist Jean-Pierre Vigier cannot be considered highly speculative as a myopic critic might surmise. The 8th Vigier Symposium proceedings 'The Physics of Reality' should in fact be touted as a companion volume because of its dramatic theoretical Field Mechanics in additional dimensionality. Many still consider the Planck-scale zero-point field stochastic quantum foam as the 'basement of reality'. This could only be considered true under the limitations of the Copenhagen interpretation of quantum theory. As we enter the next regime of Unified Field Mechanics we now know that the energy-dependent Einstein-Minkowski manifold called spacetime has a finite radius beyond which a large-scale multiverse beckons. So far a battery of 14 experiments has been designed to falsify the model. When the 1st is successfully performed, a revolution in Natural Science will occur! This volume strengthens and expands the theoretical and experimental basis for that immanent new age.

Using Cartan's differential 1-forms theory, and assuming that the motion variables depend on Euclidean invariants, certain dynamics of the material point and systems of material points are developed. Within such a frame, the Newtonian force as mass inertial interaction at the intragalactic scale, and the Hubble-type repulsive interaction at intergalactic distances, are developed.The wave-corpuscle duality implies movements on curves of constant informational energy, which implies both quantizations and dynamics of velocity limits.Analysis of motion of a charged particle in a combined field which is electromagnetic and with constant magnetism implies fractal trajectories. Mechanics of material points in a fractalic space is constructed, and various applications - fractal atom, potential well, free particle, etc. - are discussed.
