Book Description
o beaute sans seconde SeuIe sembIabIe Ii toi SOLEIL pour tout Ie monde ... JEAN-FRANc;OIS SARASIN (1615-1654) The last decade has seen the publication of monographs covering most areas of solar activity: flares (Smith and Smith, 1963), sunspots (Bray and Loughhead, 1964) and the corona (Billings, 1966). Consequently, of all the major manifestations of solar activity only prominences are without a comprehensive and unified treatment in the current literature. The present book is written in an attempt to remedy this situation, and to furnish an account of some of the most spectacular and most beautiful aspects of solar activity. Our ultimate aim is an understanding of the physical processes involved. I hope that this book may provide if only a small step toward this goal. After an historical introduction and some general definitions Chapter I proceeds with an account of several classification schemes for prominences. Most of the observational material is presented in Chapter II and forms the basis on which different models of prominences are built in Chapter III. Chapters IV and V give most of the physics of prominences, treating, as they do, the formation and stability of these objects. The interaction of prominences with other manifestations of solar activity is the subject of Chapter VI, and the final Chapter VII considers prominences in the larger context: as an integral part of the corona.

Book Description
"He is beautiful and radiant with great splendor ... " St. Francis, from Cantico del sole Two decades have elapsed since the publication of Solar Prominences, 20 years that have seen a nearly phenomenal increase in the interest, as well as the infor mation, concerning these fascinating and beautiful manifestations of solar ac tivity. During this period many meetings have been held, and several books and proceedings have been published, all dealing with specific aspects of solar prominences. However, no unifying and comprehensive accord has appeared. Recently some of my colleagues suggested that the time was ripe for a new addition of Solar Prominences, and Kluwer Academic Publishers wanted to pub lish such a book. I, therefore, venture to present this monograph in the hope of kindling the interest of some graduate students in the study of this-probably the most spectacular and often the most beautiful of solar activity manifestation. However, since it is the physical processes behind these events that will particu larly interest us, I also hope the book may be of help to some of my colleagues. In a rapidly developing field of science it is difficult, if not impossible, to present an overview that is up to date in every respect. I have made nearly every effort to include the latest contributions in the broad area of prominence research, but I am sure I have overlooked some important investigations. For these oversights, I apologize.

Book Description
This volume presents the latest research results on solar prominences, including new developments on e.g. chirality, fine structure, magnetism, diagnostic tools and relevant solar plasma physics. In 1875 solar prominences, as seen out of the solar limb, were described by P.A. Secchi in his book Le Soleil as "gigantic pink or peach-flower coloured flames". The development of spectroscopy, coronagraphy and polarimetry brought tremendous observational advances in the twentieth century. The authors present and discuss exciting new challenges (resulting from observations made by space and ground-based telescopes in the 1990s and the first decade of the 21st century) concerning the diagnostics of prominences, their formation, their life time and their eruption along with their impact in the heliosphere (including the Earth). The book starts with a general introduction of the prominence “object” with some historical background on observations and instrumentation. In the next chapter, the various forms of prominences are described with a thorough attempt of classification. Their thermodynamic (and velocity) properties are then derived with emphasis on the methods (and their limits) used. This goes from the simplest optically thin case to the heavy radiative treatment of plasmas out of local thermodynamic equilibrium. The following chapters are devoted to the magnetic field measurements and indirect derivation. A new branch of diagnostic tools, the seismology, is presented along with some MHD basics. This allows to better understand the propagation of waves, the energy and force equilibria. Both small-scale and large-scale studies and their relationship are presented. The importance of the newly discovered cavities is stressed in the context of prominence destabilization. The issues of prominence formation and eruption, their connection with flares and Coronal Mass Ejections and their impact on the Earth are addressed on the basis of the latest results. Finally, an exciting new area of research is unveiled with the newly discovered evidence of similar manifestations in the Universe and their possible impact on the habitability of exoplanets. References to the basic physics (where necessary) are provided and the proposed web sites addresses will allow the reader to load exciting movies. The book is aimed at advanced students in astrophysics, post-graduates, solar physicists and more generally astrophysicists. Amateurs will enjoy the many new images which go with the text.

Book Description
Prominences are amazing objects of great beauty whose formation, basic structure and eruption represent one of the basic unsolved problems in Solar Physics. It is now 14 years since the last book on prominences appeared (Tandberg-Hanssen, 1974), during which time much progress in our knowledge of the physics of prominences has been made, and so the time is ripe for a new text book which it is hoped will be a helpful summary of the subject for students, postdocs and solar researchers. Indeed, the last few years has seen an upsurge in interest in prominences due to high resolution ground-and space-based observations and advances in theory. For example, an IAU colloquium was held in Oslo (Jensen et al, 1978), a Solar Maximum Mission Workshop took place at Goddard Space Right Center (poland, 1986), an IAU Colloquium is planned in Yugoslavia in September 1989 in prominences and it is expected that the SOHO satellite will be a further stimulus to prominence research. In November 1987 a Workshop on the Dynamics and Structure of Solar Prominences was held in Palma Mallorca at the invitation of Jose Luis Ballester with the aim of bringing observers and theorists together and having plenty of time for in-depth discussions of the basic physics of promi nences.

Book Description
Early Solar Physics reviews developments in solar physics, particularly the advent of solar spectroscopy and the discovery of relationships between the various layers of the solar atmosphere and between the different forms of solar activity. Topics covered include solar observations during 1843; chemical analysis of the solar atmosphere; the spectrum of a solar prominence; and the solar eclipse of December 12, 1871. Spectroscopic observations of the sun are also presented. This book is comprised of 30 chapters and begins with an overview of ideas about the sun in the mid-nineteenth century, followed by a summary of progress in astronomy between 1850 and 1900, including observations of the solar surface, sunspots, and solar flares. The founding of the Mount Wilson Solar Observatory is cited. Observations of the sun made with solar spectroscopy are presented, including those of the sun's temperature. The results of a detailed examination of spectra photographed during the solar eclipse of January 22, 1898 are also discussed. The final chapter examines the magnetic properties of the earth and sun. This monograph will be a useful resource for astronomers, astrophysicists, and those interested in discovering many aspects of the sun.

Book Description
Since humans first looked up at the stars, astronomy has had a particular ability to stir the imagination and challenge the thinking of scientists and non-scientists alike. Astronomy: The Human Quest for Understanding is an introductory astronomy textbook specifically designed to relate to non-science majors across a wide variety of disciplines, nurture their curiosity, and develop vital science-based critical-thinking skills. This textbook provides an introduction to how science operates in practice and what makes it so successful in uncovering nature's secrets. Given that the study of astronomy dates back thousands of years, it is the ideal subject for tracing the development of the physical sciences and how our evolving understanding of nature has influenced, and been influenced by, mathematics, philosophy, religion, geography, politics, and more. This historical approach also illustrates how wrong turns have been taken, and how the inherent self-correcting nature of science through constant verification and the falsifiability of truly scientific theories ultimately leads us back to a more productive path in our quest for understanding. This approach also points out why, as a broadly educated citizenry, students of all disciplines must understand how scientists arrive at conclusions, and how science and technology have become central features of modern society. In discussing this fascinating and beautiful universe of which we are a part, it is necessary to illustrate the fundamental role that mathematics plays in decoding nature's mysteries. Unlike other similar textbooks, some basic mathematics is integrated naturally into the text, together with interpretive language, and supplemented with numerous examples; additional tutorials are provided on the book's companion website. Astronomy: The Human Quest for Understanding leads the reader down the path to our present-day understanding of our Solar System, stars, galaxies, and the beginning and evolution of our universe, along with profound questions still to be answered in this ancient, yet rapidly changing field.

Book Description
In this dissertation, the structure, dynamics and evolution of two quiescent prominences were studied. Quiescent prominences are large structures and mainly associated with the quiet Sun region. For the analysis, the high spatial and temporal cadence data from the Solar Dynamic Observatory (SDO), and the Solar Terrestrial Relations Observatory (STEREO) were used. The observations from two different directions were combined and the prominence in 3D were studied. In the study of polar crown prominence, the prominence flows on limb were mainly investigated and its association with on-disk brightenings were found. The merging of diffused active region flux in the already formed chain of prominence caused the several brightenings in the filament channel and also injected the plasma upward with an average velocity of 15 km/s. In another study, the triggering mechanism of a quiescent tornado-like prominence was investigated. Flares from the neighboring active region triggered the tornado-like motions on the top of the prominence. Active region field contracts after the flare which results in the expansion of prominence cavity. The prominence helical magnetic field expands and plasma moves along the field lines which appear as a tornado-like activity. These observational investigations led to the understanding of structure and dynamics of quiescent prominences, which could be useful for theoretical prominence models.
