This is the first scholarly collection of articles focused on the cultural astronomy of the African continent. It weaves together astronomy, anthropology, and Africa and it includes African myths and legends about the sky, alignments to celestial bodies found at archaeological sites and at places of worship, rock art with celestial imagery, and scientific thinking revealed in local astronomy traditions including ethnomathematics and the creation of calendars.
This book is the fourth volume under the title Organizations and
Strategies in Astronomy (OSA). These OSA Books are intended to
cover a large range of fields and themes. In practice, one could
say that all aspects of astronomy-related life and environment are
considered in the spirit of sharing specific expertise and lessons
learned.
In recent years aperture synthesis and interferometry have become very powerful tools in radioastronomy. Investigation of distant galaxies, for example, have revealed structures with sizes of less than a kiloparsec. In general, the study of galaxies has benefited from the great power of these techniques. Radar applications have also dramatically increased their quality by using the interferometry principle. Tracking and airborne radar can now determine position and velocity of objects with a much higher accuracy. This book describes in the first six, short chapters the basics of interferometry and aperture synthesis. The following two, long chapters treat the aspects of radioastronomical interferometers and radar applications of interferometry in great detail. The text offers readers a very good opportunity to familiarize themselves with the mathematical background of these very complex techniques. For researchers and students in radioastronomy and electrical engineering.

Our Galactic center's proximity allows astronomers to study physical pro cesses within galactic nuclei at a level of detail that will never be possible in the more distant, but usually also more spectacular, extragalactic systems. Recent advances in instrumentation from the radio, through the submillime ter and infrared wavebands, and out to the X- and "'(-ray bands now allow observations of the Galactic Center over thirteen orders of magnitude in wave length. Our knowledge about the central few hundred parsecs of our Galaxy has consequently increased vastly over the past decade. The same new instru ments provide high resolution, high quality measurements of nearby ''normal'' galactic nuclei; that is, nuclei whose modest energy output is comparable to that of our own (and most other) galaxies. Theorists, spurred in part by the new observations, have been able to refine models of the energetics, dynam ics, and evolution of the gas and stellar systems deep within galactic nuclei."
Astronomers communicate all the time, with colleagues of course,
but also with managers and administrators, with decision makers and
takers, with social representatives, with the news media, and with
society at large. Education is naturally part of the process.
Astronomy communication must take into account several specifics:
the astronomy community is rather compact and well organized
world-wide; astronomy has penetrated the general public remarkably
well with an extensive network of associations and organizations of
aficionados all over the world. Also, as a result of the huge
amount of data accumulated and by necessity for their extensive
international collaborations, astronomers have pioneered the
development of distributed resources, electronic communications and
networks coupled to advanced methodologies and technologies, often
long before they become commonly used world-wide.

The second edition of this book has been completely updated. It studies the history and gives an analysis of extreme climate change on Earth. In order to provide a long-term perspective, the first chapter briefly reviews some of the wild gyrations that occurred in the Earth's climate hundreds of millions of years ago: snowball Earth and hothouse Earth. Coming closer to modern times, the effects of continental drift, particularly the closing of the Isthmus of Panama are believed to have contributed to the advent of ice ages in the past three million years. This first chapter sets the stage for a discussion of ices ages in the geological recent past (i.e. within the last three million years, with an emphasis on the last few hundred thousand years).
Here is a fascinating text that integrates topics pertaining to all scales of the MHD-waves, emphasizing the linkages between the ULF-waves below the ionosphere on the ground and magnetospheric MHD-waves. It will be most helpful to graduate and post-graduate students, familiar with advanced calculus, who study the science of MHD-waves in the magnetosphere and ionosphere. The book deals with Ultra-Low-Frequency (ULF)-electromagnetic waves observed on the Earth and in Space.
Limiting Outer Space propels the historicization of outer space by focusing on the Post-Apollo period. After the moon landings, disillusionment set in. Outer space, no longer considered the inevitable destination of human expansion, lost much of its popular appeal, cultural significance and political urgency. With the rapid waning of the worldwide Apollo frenzy, the optimism of the Space Age gave way to an era of space fatigue and planetized limits. Bringing together the history of European astroculture and American-Soviet spaceflight with scholarship on the 1970s, this cutting-edge volume examines the reconfiguration of space imaginaries from a multiplicity of disciplinary perspectives. Rather than invoking oft-repeated narratives of Cold War rivalry and an escalating Space Race, Limiting Outer Space breaks new ground by exploring a hitherto underrated and understudied decade, the Post-Apollo period.
This work investigates the permissibility and viability of property rights on the - lestial bodies, particularly the extraterrestrial aspects of land and mineral resources ownership. In lay terms, it aims to ?nd an answer to the question "Who owns the Moon?" The ?rst chapter critically analyses and dismantles with legal arguments the issue of sale of extraterrestrial real estate, after having perused some of the trivial claims of celestial bodies ownership. The only consequence these claims have on the plane of space law is to highlight the need for a better regulation of extraterrestrial landed property rights. Next, thebook addresses theapparent silenceofthelawinthe?eldofextraterr- trial landed property, scrutinizing whether the factual situation on the extraterrestrial realms calls for legal regulations. The sources of law are examined in their dual dimension - that is, the facts that have caused and shaped the law of extraterrestrial real estate, and the norms which express this law. It is found that the norms and rules regarding property rights in the celestial realms are rather limited, failing to de?ne basic concepts such as celestial body.
This book presents the basics and advanced topics of research of gamma ray physics. It describes measuring of Fermi surfaces with gamma resonance spectroscopy and the theory of angular distributions of resonantly scattered gamma rays. The dependence of excited-nuclei average lifetime on the shape of the exciting-radiation spectrum and electron binding energies in the spectra of scattered gamma rays is described. Resonant excitation by gamma rays of nuclear isomeric states with long lifetime leads to the emission and absorption lines. In the book, a new gamma spectroscopic method, gravitational gamma spectrometry, is developed. It has a resolution hundred million times higher than the usual Moessbauer spectrometer. Another important topic of this book is resonant scattering of annihilation quanta by nuclei with excited states in connection with positron annihilation. The application of the methods described is to explain the phenomenon of Coulomb fragmentation of gamma-source molecules and resonant scattering of annihilation quanta to study the shape of Fermi surfaces of metals.
This volume of the Highlights of Astronomy contains the Invited Discourses and the proceedings or summaries of Joint Discussions, Special Sessions, and Working Group Meetings held at the XIInd IAU General Assembly in August 1994 in The Hague. While the three Invited Discourses are reproduced in the order of their appearance in the meeting programme, the Joint Discussions have been reordered according to their topics. Not included in this volume are the proceedings of the GA Symposia which will be published individually in the IAU Symposia series. I am most grateful to the authors of the invited discourses for preparing manuscripts in spite of heavy other commitments. It is a pleasure to express my appreciation of the work by Dr. Jacqueline Bergeron in organizing the XXIInd General Assembly, and I wish to thank all authors and meeting chairpersons for their cooperation and for providing their contributions in time to meet the customary publication schedule of this series. Special thanks are due to Ms. Monique Leger-Orine from the IAU office for considerable and patient assistance in the final editing, and to Dr. Tom Herbst from the Max Planck-Institute for Astronomy for permission to reproduce on the cover of this volume one of his IR images of Jupiter obtained just after the Comet Shoemaker-Levy 9 impact, one of the definite Highlights of Astronomy in 1994.
The field of Order and Chaos had a remarkable expansion in the last 50 years. The main reason was the use of computers, and the development of new theoretical methods that we call now 'the theory of chaos'. The author describes this fascinating period in a relaxed and sometimes humorous autobiographical way. He relates his interactions with many people in dynamical astronomy and he quotes several anecdotes from these interactions. He refers also to his experiences when he served in various international positions, such as general secretary of the IAU and chairman of the journal Astronomy and Astrophysics. In recent years the theory of chaos has been extended to new areas, like relativity, cosmology and quantum mechanics and it continues expanding in almost all branches of physics. The book describes many important ideas in this field in a simple way. It refers also to problems of more general interest, like writing papers and giving lectures and the interaction of authors and referees. Finally it gives some useful prospects for the future of dynamical astronomy and related fields.

This collection of papers will address the question "What is the Magnetospheric Cusp?" and what is its role in the coupling of the solar wind to the magnetosphere as well as its role in the processes of particle transport and energization within the magnetosphere. The cusps have traditionally been described as narrow funnel-shaped regions that provide a focus of the Chapman-Ferraro currents that flow on the magnetopause, a boundary between the cavity dominated by the geomagnetic field (i.e., the magnetosphere) and the external region of the interplanetary medium. Measurements from a number of recent satellite programs have shown that the cusp is not confined to a narrow region near local noon but appears to encompass a large portion of the dayside high-latitude magnetosphere. It appears that the cusp is a major source region for the production of energetic charged particles for the magnetosphere. This book will be of great interest to scientists in Space Physics as well as to those working in research organizations in governments and industries, university departments of physics, astronomy, space physics, and geophysics. Part of this book has already been published in a journal.
Der bekannte Astronom Karl Schwarzschild (1873-1916) gilt als der Begr}nder der Astrophysik und als hervorragender Forscher mit einer erstaunlichen Bandbreite seiner Interessen. Arbeiten zur Himmelsmechanik, Elektrodynamik und Relativit{tstheorie weisen ihn als vorz}glichen Mathematiker und Physiker seiner Zeit aus. Untersuchungen zur Photographischen Photometrie, Optik und Spektroskopie zeigen den versierten Beobachter, der sein Me instrument beherrscht. Schlie lich arbeitete Schwarzschild als Astrophysiker und an Sternatmosph{ren, Kometen, Struktur und Dynamikvon Sternsystemen. Die in seinem kurzen Leben entstandene F}lle von wissenschafltichen Arbeiten ist in drei B{nden der Gesamtausgabe gesammelt, erg{nzt durch biographisches Material und ein Essay des Nobelpreistr{gers S. Chandrasekhar und Annotationen von Fachleuten in jedem der drei B{nde.
Neutron stars, whether isolated or in a binary system, display a varied and complex phenomenology, often accompanied by extreme variability of many time scales, which takes the form of pulsations due to the object rotation, quasi-periodicities associated to accretion of matter, and explosions due to matter accreted on the surface or to starquakes of highly magnetized objects. This book gives an overview of the current observational and theoretical standpoint in the research on the physics under the extreme conditions that neutron stars naturally provide. The six chapters explore three physical regions of a neutron star: the space around it, where accretion and pulsar companions allow testing of general relativity its surface, where millisecond pulsation and X-ray burts provide clues about general relativistic effects and the equation of state of neutron matter its interior, of course, inaccessible to direct observations, can nevertheless, be probed with all observational parameters related to neutron star variability.
[the text below needs editing and we must be careful not to say things about Dan Brown's book that could get Springer in legal trouble] Dan Brown's novel, The Da Vinci Code, was first published in 2003; its sales have reached 40 million worldwide. The book mixes a small spice of fact into a large dollop of fiction to create an entertaining novel of intrigue, adventure, romance, danger and conspiracy, which have been imaginatively worked together to cook up the successful bestseller. Most interest in the book's origins has centred on the sensational religious aspects. Dan Brown has written: 'All of the art, architecture, secret rituals, secret societies, all of that is historical fact.' This gives an air of authenticity to the book. Brown has, however, made up the religious doctrines, or based them on questionable accounts by others. The locations of the actions of The Da Vinci Code are not, however, made up. The present book is the scientific story behind the scene of several of the book's actions that take place on the axis of France that passes through Paris. The Paris Meridian is the name of this location. It is the line running north-south through the astronomical observatory in Paris. One of the original intentions behind the founding of the Paris Observatory was to determine and measure this line. The French government financed the Paris Academy of Sciences to do so in the seventeenth to nineteenth centuries. It employed both astronomers - people who study and measure the stars - and geodesists - people who study and measure the Earth. This book is about what they did and why. It is a true story behind Dan Brown's fiction. This is the first English language presentation of this historical material. It is attractively written and it features the story of the community of scientists who created the Paris Meridian. They knew each other well - some were members of the same families, in one case of four generations. Like scientists everywhere they collaborated and formed alliances; they also split into warring factions and squabbled. They travelled to foreign countries, somehow transcending the national and political disputes, as scientists do now, their eyes fixed on ideas of accuracy, truth and objective, enduring values - save where the reception given to their own work is concerned, when some became blind to high ideals and descended into petty politics. To establish the Paris Meridian, the scientists endured hardship, survived danger and gloried in amazing adventures during a time of turmoil in Europe, the French Revolution and the Napoleonic War between France and Spain. Some were accused of witchcraft. Some of their associates lost their heads on the guillotine. Some died of disease. Some won honour and fame. One became the Head of State in France, albeit for no more than a few weeks. Some found dangerous love in foreign countries. One scientist killed in self defence when attacked by a jealous lover, another was himself killed by a jealous lover, a third brought back a woman to France and then jilted her, whereupon she joined a convent. The scientists worked on practical problems of interest to the government and to the people. They also worked on one of the important intellectual problems of the time, a problem of great interest to their fellow scientists all over the world, nothing less than the theory of universal gravitation. They succeeded in their intellectual work, while touching politics and the affairs of state. Their endeavours have left their marks on the landscape, in art and in literature.
Supernovae are among the most energetic phenomena in the Universe and - lated to almost all aspects of modern astrophysics including starburst gal- ies, cosmic ray acceleration, neutron star and black hole formation, nuc- osynthesis and ISM chemical enrichment, energy input to the ISM, cosmic distance scale determination, dark energy related cosmological acceleration, gamma-ray bursts, extra-solar system neutrino burst detection, gravity wave generation, and many more. Additionally, the past 15 years have been p- ticularly productive with many new results and new understanding due in particular to the closest SN in 400 years in SN 1987A in the Large M- ellanic Cloud, and the unusually bright and close SN 1993J and SN 1994I in the nearby galaxies M81 and M51, respectively. In addition, the disc- ery of the ?-ray burst GRB 980425 and its related supernova SN 1998bw, and the con?rmation of GRB 030329/SN 2003dh, tied the study of SNe and GRBs inextricably together. With the many developments since the last - jor supernova meeting in La Serena, Chile in 1997, we felt that it was an appropriate time to bring together experts and students interested in the subject for a meeting where SN and GRB properties and interrelationships could be discussed. The tenth anniversary of SN 1993J provided such an - portunity and, appropriately, the meeting was held in Spain where SN 1993J was discovered on the early morning of 28 March 1993 by a Spanish amateur astronomer, Francisco Garc ?a.
Since the first rocket-technology experiments of the early 20th century, space exploration has captivated the world. Recent advances and setbacks have included the new discoveries from the Galileo mission, the Mars Global Surveyor's revelation that water once existed on the Red Planet, the International Space Station, the advent of space tourism, and the devastating Space Shuttle disasters. This one-stop guide to space exploration provides a wealth of information for student researchers. A substantial 'Chronology of Events' and a narrative history outline the key events and people in the progression of space research and activity. Five topical essays--including a look at the Space Shuttle--examine several significant issues related to the politics and technology of space exploration from an international perspective. These chapters elucidate several sets of documents that give shape and substance to the larger story. Primary documents in this volume are organized by theme and represent the variety of materials available to anyone seeking a better understanding of the rise of space exploration. Also included are biographical sketches of key people associated with space flight, a listing of the human space flight missions undertaken since 1961, and an annotated bibliography of additional reading.
These proceedings summarize our present knowledge on astronomical molecules, highlight major problems to be addressed, and finally propose future work. Their theoretical understanding involves physics, numerical simulations and chemistry.
This proceedings covers topics from chemical abundances in the different components of the Milky Way and in local group galaxies, via observational and theoretical papers on mixing in stars to big bang nucleosynthesis and galaxy formation and evolution. Like all volumes in the series ESO Astrophysics Symposia, this one gives a comprehensive overview of the forefront of research in this subject. It is a valuable reference for both students and researchers. |
