DOWNLOAD EBOOKIn this classic text, a Nobel Prize-winning astrophysicist presents the theory of stellar dynamics as a branch of classical dynamics--a discipline in the same general category as celestial mechanics. His method offers the advantages of clarifying the theory's fundamental issues and defining its underlying motivations. S. Chandrasekhar investigates two areas. The first concerns problems in which the time of relaxation of a stellar system is central. His method consists of analyzing the effects of stellar encounters in terms of the two-body problem of classical dynamics and applying this theory to the dynamics of star clusters. The second area investigates problems centering around Liouville's theorem and the solutions of the equation of continuity; here, the author discusses the dynamic implications of the existence of a field of differential motions, which appears to be the most striking kinematic feature of the galaxy and the extragalactic systems. This edition includes two papers by the author that were published after Principles of Stellar Dynamics and that have been studied and quoted extensively: "New Methods in Stellar Dynamics" (originally published in the Annals of the New York Academy of Sciences) and "Dynamical Friction" (originally published in The Astrophysical Journal).

DOWNLOAD EBOOKIn terms of the scale of the galaxy, both in space and time, we humans are new comers. Though we are newly on the scene, we are already thinking about how to create large structures in space. Recently, analysis of data from one of the stars in the Kepler data set has led to speculation regarding huge artificial structures (called Stapledon/Dyson Spheres) constructed by advanced extraterrestrial civilizations. The NASA Kepler space observatory has been observing light curves of about 100,000 stars in the constellations of Cygnus and Lyre. This star, popularly dubbed “Tabby’s Star” after the first name of the astronomer leading one of the data reduction teams, shows intriguing periodic dips in its luminosity. Stellar Engineering starts by considering terrestrial organisms, and early humans, who have constructed, on their scale, “megastructures,” and continues with a history of the development of the stellar engineering concept. Kepler data on the subject star is reviewed as is observational data on other possible Stapledon/Dyson Sphere candidates. Possible applications of such enormous constructs are discussed, as well as the intriguing speculation that we might live in a Stapledon/Dyson swarm of alien space habitats within our Solar System’s Kuiper Belt. The chapter frontispiece art illuminates the ideas presented.

DOWNLOAD EBOOKDynamics of Stellar Systems focuses on the theoretical problems in stellar dynamics. The book first offers information on stellar dynamics, including historical development, fundamentals of synthetic method, and value of stellar dynamics. The text discusses the fundamental concepts of stellar statistics. Properties of univariate distribution functions; multivariate distribution functions; and statistical properties of stars are explained. The text then describes the elementary theory of galactic rotation and irregular forces in stellar systems. The text also tackles statistical stellar dynamics of neglecting encounters. Considerations include Boltzmann equation in curvilinear coordinates; importance of using one-valued integrals of the motion; and fundamental differential equation of stellar dynamics. The book also underscores the regular orbit of stars and dynamics of centroids. The text describes the dynamics of spherical stellar and rotating stellar systems. The theory of polytropic spheres; basic equations for spherical systems; masses and rotation of galaxies; and boundaries of galaxies are discussed. The text is highly recommended for readers interested in stellar dynamics.

DOWNLOAD EBOOKThis volume contains invited papers and contributions delivered at the International Conference on Hamiltonian Mechanics: Integrability and Chaotic Behaviour, held in Tornn, Poland during the summer of 1993. The conference was supported by the NATO Scientific and Environmental Affairs Division as an Advanced Research Workshop. In fact, it was the first scientific conference in all Eastern Europe supported by NATO. The meeting was expected to establish contacts between East and West experts as well as to study the current state of the art in the area of Hamiltonian Mechanics and its applications. I am sure that the informal atmosphere of the city of Torun, the birthplace of Nicolaus Copernicus, stimulated many valuable scientific exchanges. The first idea for this cnference was carried out by Prof Andrzej J. Maciejewski and myself, more than two years ago, during his visit in Greece. It was planned for about forty well-known scientists from East and West. At that time participation of a scientist from Eastern Europe in an Organising Committee of a NATO Conference was not allowed. But always there is the first time. Our plans for such a "small" conference, as a first attempt in the new European situation -the Europe without borders -quickly passed away. The names of our invited speakers, authorities in their field, were a magnet for many colleagues from all over the world.

DOWNLOAD EBOOKImpact phenomena play an essential role in the formation of planets and great influence during their evolution. The first part of this book describes the dynamics that propels asteroids in our solar system; the second part is devoted to impact phenomena; the third inspects terrestrial impacts of asteroids and the hazards due to space debris orbiting our planet. The book addresses scientists working in astronomy, extraterrestrial physics and geophysics. But it should also be of great interest to a learned public that wants to know about the most recent developments in this fast-moving field of theoretical and observational research.
Origin And Evolution Of Comets: Ten Years After The Nice Model And One Year After Rosetta

DOWNLOAD EBOOKSince several decades, comets have been considered as key witnesses of solar system formation. Their nature has been explored using the modern arsenal of Earth- and space-based observations, and they hold a central place as dynamical arbiters of the planetary system in the new paradigm of solar system evolution known as the Nice Model. Thus, they have the potential to test the various ideas, using the detailed data recently gathered by the ESA/Rosetta mission. This requires an understanding of their origin and evolution, which form the subject of the present book. All the relevant issues are covered, describing both the background and the current frontiers of research.

DOWNLOAD EBOOKMartin Shingler presents the mother volume for Palgrave's Film Stars series in three easily-navigable chapters in which he provides a summative and instructive account of star studies for today's film student. Via a critical evaluation of the work of leading film scholars, he provides a convincing argument for howthis important area of film studies has evolved. Building on this, he offerssome new directions for star scholarship, and ends by offering the film student a useful set of themes and issues for his or her own investigation. 'Star Studies' is the perfect companion for the student who wishes to foster further research on stardom across a wide range of contexts, from national cinemas, to mainstream and marginal cinemas, to different historical periods and beyond.
