Book Description
The original plans for a meeting to celebrate the second centenary of the As tronomical Observatory of Palermo were for a celebration with a double character. The gathering was to have both a historical character, appropriate for a bicenten nial, and a technical character, to note and chronicle the new phase of the history of the Observatory, which has prospered in parallel with the development of this fairly recent topic in astronomical research, the physics of stellar and solar coronae. After the untimely death of the Observatory's Director, Giuseppe S. Vaiana (Pippo to his many friends), a number of colleagues and friends insisted that the celebration should nevertheless be held and should be dedicated to this farsighted scientist who stimulated the development of coronal physics from the early x-ray observations of the solar corona to the recognition of coronae as an observable feature of nearly all stars. This memorial dedication did not change the character of the meeting, which was held in Palermo from 22 to 26 June 1992; as his contributions are very alive in the papers presented at the meeting and collected here, Pippo Vaiana has certainly achieved his place in the history of Astronomy.

Book Description
The Physics of Solar and Stellar Coronae provides the first comprehensive summary of the physical processes and phenomena occurring in solar and stellar coronae as observed at X-ray and other wavelengths. The book provides an early summary of the spectacular new solar X-ray observations being obtained with the Yohkoh satellite that are dramatically changing our understanding of the dynamics of the solar corona. With the perspective of two years' observations at X-ray and extreme ultraviolet wavelengths by the ROSAT satellite, many authors present new insights into the basic physical processes occurring in the coronae of stars across the Hertzsprung--Russell Diagram including both pre-main sequence and post-main sequence stars. Detailed models for the hot plasmas typically contained in magnetic loops in both stellar and solar coronae are presented to explain X-ray data obtained with the earlier X-ray instruments on Skylab, SMM, Einstein, and EXOSAT. The book includes papers on coronal observations obtained at other wavelengths and papers of the history of Palermo Astronomical Observatory. The Physics of Solar and Stellar Coronae is intended for researchers in the fields of solar physics and stellar astrophysics and will be a useful resource book for graduate level astrophysics courses. (ABSTRACT) This is the first comprehensive summary of the physical processes and phenomena occurring in solar and stellar coronae. Spectacular new solar X-ray observations by the Yohkoh satellite and stellar observations by ROSAT are highlighted, together with theoretical papers and detailed analyses of earlier data from Skylab, SMM, Einstein, and EXOSAT.

Book Description
This textbook is intended as an introduction to the physics of solar and stellar coronae, emphasizing kinetic plasma processes. It is addressed to observational astronomers, graduate students, and advanced undergraduates without a ba- ground in plasma physics. Coronal physics is today a vast field with many different aims and goals. So- ing out the really important aspects of an observed phenomenon and using the physics best suited for the case is a formidable problem. There are already several excellent books, oriented toward the interests of astrophysicists, that deal with the magnetohydrodynamics of stellar atmospheres, radiation transport, and radiation theory. In kinetic processes, the different particle velocities play an important role. This is the case when particle collisions can be neglected, for example in very brief phenomena – such as one period of a high-frequency wave – or in effects produced by energetic particles with very long collision times. Some of the most persistent problems of solar physics, like coronal heating, shock waves, flare energy release, and particle acceleration, are likely to be at least partially related to such p- cesses. Study of the Sun is not regarded here as an end in itself, but as the source of information for more general stellar applications. Our understanding of stellar processes relies heavily, in turn, on our understanding of solar processes. Thus an introduction to what is happening in hot, dilute coronae necessarily starts with the plasma physics of our nearest star.

IAU Transactions are published as a volume corresponding to each General Assembly. Volume A is produced prior to the Assembly and contains Reports on Astronomy, prepared by each Commission President. The intention is to summarize the astronomical results that have affected the work of the Commission since the production of the previous Reports up to a time which is about one year prior to the General Assembly. Volume B is produced after the Assembly and contains accounts of Commission Meetings which were held, together with other material. The reports included in the present volume range from outline summaries to lengthy compilations and references. Most reports are in English.

Book Description
The multielement systems have been widely used in many fields of astron omy and radio science in the last decades. This is caused by the increasing demands on the resolution and sensitivity of such systems over the wide range of the electromagnetic wavelengths, from gamma up to radio. The ground-based optical and radio interferometers, gamma-ray and X-ray or bital telescopes, antenna arrays of radio telescopes and also some other radio devices belong to scientific instruments using multielement systems. There fore, the current problems of the optimal construction of such systems, or precisely, those of searching for the best arrangement of the elements in them, were formulated. A rather large number of scientific papers, including those of the authors, is devoted to these problems, and we believe that the time has come to integrate the basic results of the papers into the mono graph. The offered book consists of three parts. The first part is concerned with the optimal synthesis of optical and radio interferometers of various types and purposes; the synthesis of non-equidistant antenna arrays is con sidered in the second part; and the methods for the construction of coded masks for X-ray and gamma-ray orbital telescopes are expounded in the third one. Since in the text combinatorial constructions which are little known to astronomers are used, the necessary information is given in the appendices. Various tables containing the parameters of the systems consid ered are also represented.

Book Description
Space exploration and advanced astronomy have dramatically expanded our knowledge of outer space and made it possible to study the indepth mechanisms underlying various natural phenomena caused by complex interaction of physical-chemical and dynamical processes in the universe. Huge breakthroughs in astrophysics and the planetary s- ences have led to increasingly complicated models of such media as giant molecular clouds giving birth to stars, protoplanetary accretion disks associated with the solar system’s formation, planetary atmospheres and circumplanetary space. The creation of these models was promoted by the development of basic approaches in modern - chanics and physics paralleled by the great advancement in the computer sciences. As a result, numerous multidimensional non-stationary problems involving the analysis of evolutionary processes can be investigated using wide-range numerical experiments. Turbulence belongs to the most widespread and, at the same time, the most complicated natural phenomena, related to the origin and development of organized structures (- dies of different scale) at a definite flow regime of fluids in essentially non-linear - drodynamic systems. This is also one of the most complex and intriguing sections of the mechanics of fluids. The direct numerical modeling of turbulent flows encounters large mathematical difficulties, while the development of a general turbulence theory is hardly possible because of the complexity of interacting coherent structures. Three-dimensional non-steady motions arise in such a system under loss of la- nar flow stability defined by the critical value of the Reynolds number.

Book Description
British University Observatories fills a gap in the historiography of British astronomy by offering the histories of observatories identified as a group by their shared characteristics. The first full histories of the Oxford and Cambridge observatories are here central to an explanatory history of each of the six that undertook research before World War II - Oxford, Dunsink, Cambridge, Durham, Glasgow and London. Each struggled to evolve in the middle ground between the royal observatories and those of the 'Grand Amateurs' in the nineteenth century. Fundamental issues are how and why astronomy came into the universities, how research was reconciled with teaching, lack of endowment, and response to the challenge of astrophysics. One organizing theme is the central importance of the individual professor-directors in determining the fortunes of these observatories, the community of assistants, and their role in institutional politics sometimes of the murkiest kind, patronage networks and discipline shaping coteries. The use of many primary sources illustrates personal motivations and experience. This book will intrigue anyone interested in the history of astronomy, of telescopes, of scientific institutions, and of the history of universities. The history of each individual observatory can easily be followed from foundation to 1939, or compared to experience elsewhere across the period. Astronomy is competitive and international, and the British experience is contextualised by comparison for the first time to those in Germany, France, Italy and the USA.
