D. R. Lorimer, M. Kramer
R1,459 Discovery Miles 14 590 Ships in 12 - 17 working days

Radio pulsars are rapidly rotating highly magnetized neutron stars. Studies of these fascinating objects have provided applications in solid-state physics, general relativity, galactic astronomy, astrometry, planetary physics and even cosmology. Most of these applications and much of what we know about neutron stars are derived from single-dish radio observations using state-of-the-art receivers and data acquisition systems. This comprehensive 2004 book is a unique resource that brings together the key observational techniques, background information and a review of results, including the discovery of a double pulsar system. Useful software tools are provided which can be used to analyse example data, made available on a related website. This work will be of great value not only to graduate students but also to researchers wishing to carry out and interpret a wide variety of radio pulsar observations.

Black Holes in Higher Dimensions (Hardcover, New): Gary T. Horowitz Black Holes in Higher Dimensions (Hardcover, New)
Gary T. Horowitz
R2,031 Discovery Miles 20 310 Ships in 12 - 17 working days

Black holes are one of the most remarkable predictions of Einstein's general relativity. In recent years, ideas in brane-world cosmology, string theory and gauge/gravity duality have motivated studies of black holes in more than four dimensions, with surprising results. In higher dimensions, black holes exist with exotic shapes and unusual dynamics. Edited by leading expert Gary Horowitz, this exciting book is the first devoted to this new field. The major discoveries are explained by the people who made them: Rob Myers describes the Myers-Perry solutions that represent rotating black holes in higher dimensions; Ruth Gregory describes the Gregory-Laflamme instability of black strings; and Juan Maldacena introduces gauge/gravity duality, the remarkable correspondence that relates a gravitational theory to nongravitational physics. Accessible to anyone with a standard course in general relativity, this is an important resource for graduate students and researchers in general relativity, string theory and high energy physics.

Atlas of Galactic Neutral Hydrogen (Paperback): Dap Hartmann, W. Butler Burton Atlas of Galactic Neutral Hydrogen (Paperback)
Dap Hartmann, W. Butler Burton
R1,383 Discovery Miles 13 830 Ships in 12 - 17 working days

The authors measured atomic hydrogen, the principal component of the interstellar medium in the Milky Way, over a five-year period using the 25-meter radio telescope of the Netherlands Foundation for Research in Astronomy. Displayed in several projections, each map corresponds to a particular velocity interval; separation by velocity roughly corresponds to separation by distance, or by energetics. The Leiden/Dwingeloo survey covers the entire sky above declination -300, on a half-degree grid, over a velocity range of 1000 km/s at 1 km/s resolution. The limiting brightness temperature sensitivity is 0.07 K. A CD-ROM also accompanies the Atlas, and contains the entire dataset of the Leiden/Dwingeloo survey in computer-readable form. The CD-ROM also contains color images in GIF format, as well as animations displaying the 3-dimensional data cube.

Francis Baily, John Flamsteed
R2,419 Discovery Miles 24 190 Ships in 12 - 17 working days

John Flamsteed (1646-1719) was the first Astronomer Royal, appointed to the newly founded Greenwich Observatory. Charged with improving navigation at sea, he used meticulous telescopic observations to compile a 'Catalogue of British Stars', radically updating Tycho Brahe's previous naked-eye calculations. However he delayed publishing, leading to a vituperative quarrel with contemporaries Newton and Halley, who published his results without his permission. Flamsteed managed to destroy most of that edition - his own was published posthumously - but his reputation was damaged. A century later, Francis Baily (1774-1844), a stockbroker who became President of the Royal Astronomical Society, rediscovered Flamsteed's papers, including autobiographical writings and extensive correspondence. Their publication in this volume, along with a revised version of the catalogue, rehabilitated Flamsteed's reputation and restated the importance of methodical observation in astronomy. Today, this book illuminates both the social context of Flamsteed's work and the intellectual climate of Baily's London.

A Handbook of Double Stars - For the Use of Amateurs (Paperback): Edward Crossley, Joseph Gledhill, James M. Wilson A Handbook of Double Stars - For the Use of Amateurs (Paperback)
Edward Crossley, Joseph Gledhill, James M. Wilson
R1,418 Discovery Miles 14 180 Ships in 12 - 17 working days

Used to describe both binary systems and optical doubles, the term 'double star' has been familiar to astronomers since the seventeenth century. This book, first published in 1879, outlines the history of their study, and describes the methods and equipment needed in order to observe the fascinating phenomenon. Written for non-specialists by Fellows of the Royal Society Edward Crossley (1841-1904), Joseph Gledhill (1837-1906) and James M. Wilson (1836-1931), the catalogue of over 1,200 double stars appears beside detailed notes and does not assume mathematical expertise. Also offered are a fully worked example of how to find the orbit of a binary star, and illustrations of telescopes, observatories, and even custom-made observation chairs. This reissue includes the supplement with corrections and notes published in 1880. A standard reference text in the late nineteenth century, the work remains a resources for students and scholars of the history of astronomy.

Understanding Variable Stars (Paperback): John R. Percy Understanding Variable Stars (Paperback)
John R. Percy
R1,615 Discovery Miles 16 150 Ships in 12 - 17 working days

This book was first published in 2007. Variable stars are those that change brightness. Their variability may be due to geometric processes such as rotation, or eclipse by a companion star, or physical processes such as vibration, flares, or cataclysmic explosions. In each case, variable stars provide unique information about the properties of stars, and the processes that go on within them. This book provides a concise overview of variable stars, including a historical perspective, an introduction to stars in general, the techniques for discovering and studying variable stars, and a description of the main types of variable stars. It ends with short reflections about the connection between the study of variable stars, and research, education, amateur astronomy, and public interest in astronomy. This book is intended for anyone with some background knowledge of astronomy, but is especially suitable for undergraduate students and experienced amateur astronomers who can contribute to our understanding of these important stars.

Active Galactic Nuclei - From the Central Black Hole to the Galactic Environment (Paperback, New): Julian H. Krolik Active Galactic Nuclei - From the Central Black Hole to the Galactic Environment (Paperback, New)
Julian H. Krolik
R3,232 Discovery Miles 32 320 Ships in 10 - 15 working days

This is the first comprehensive treatment of active galactic nuclei--the cosmic powerhouses at the core of many distant galaxies. The term "active galactic nuclei" refers to quasars, radio galaxies, Seyfert galaxies, blazars, and related objects, all of which are believed to share a similar central engine--a supermassive black hole many times the mass of the Sun. Astrophysicists have studied these phenomena for the past several decades and have begun to develop a consensus about many of their properties and internal mechanisms. Julian Krolik, one of the world's leading authorities on the subject, sums up leading ideas from across the entire range of research, making this book an invaluable resource for astronomers, physicists interested in applications of the theory of gravitation, and graduate students.

Krolik begins by addressing basic questions about active galactic nuclei: What are they? How can they be found? How do they evolve? He assesses the evidence for massive black holes and considers how they generate power by accretion. He discusses X-ray and g-ray emission, radio emission and jets, emission and absorption lines, anisotropic appearance, and the relationship between an active nucleus and its host galaxy. He explores the mysteries of what ignites, fuels, and extinguishes active galactic nuclei, and concludes with a general review of where the field now stands. The book is unique in paying careful attention to relevant physics as well as astronomy, reflecting in part the importance of general relativity to understanding active galactic nuclei. Clear, authoritative, and detailed, this is crucial reading for anyone interested in one of the most dynamic areas of astrophysics today.

Peter Hoeflich, Pawan Kumar, J. Craig Wheeler
R1,561 Discovery Miles 15 610 Ships in 12 - 17 working days

Supernovae and gamma-ray bursts are the strongest explosions in the Universe. Observations show that, rather than being symmetrical, they are driven by strong jets of energy and other asymmetrical effects. These observations demand theories and computations that challenge the biggest computers. This volume marks the transition to a fresh paradigm in the study of stellar explosions. It highlights the burgeoning era of routine supernova polarimetry and the insights into core collapse and thermonuclear explosions. With chapters by leading scientists, the book summarises the status of a fresh perspective on stellar explosions and should be a valuable resource for graduate students and research scientists.

Carolus J. Schrijver, George L Siscoe
R1,479 Discovery Miles 14 790 Ships in 12 - 17 working days

Heliophysics is a developing scientific discipline integrating studies of the Sun's variability, the surrounding heliosphere, and climatic environments. Over the past few centuries, our understanding of how the Sun drives space weather and climate on the Earth and other planets has advanced at an ever-increasing rate. This volume, the first in a series of three heliophysics texts, integrates such diverse topics for the first time as a coherent intellectual discipline. It emphasizes the physical processes coupling the Sun and Earth, allowing insights into the interaction of the solar wind and radiation with the Earth's magnetic field, atmosphere and climate system. It provides a core resource for advanced undergraduates and graduates, and also constitutes a foundational reference for researchers in heliophysics, astrophysics, plasma physics, space physics, solar physics, aeronomy, space weather, planetary science and climate science. Additional online resources, including lecture presentations and other teaching materials, are accessible at www.cambridge.org/9780521110617.

Evolutionary Processes in Binary and Multiple Stars (Paperback): Peter Eggleton Evolutionary Processes in Binary and Multiple Stars (Paperback)
Peter Eggleton
R1,972 Discovery Miles 19 720 Ships in 12 - 17 working days

Binary systems of stars are as common as single stars. Stars evolve primarily by nuclear reactions in their interiors, but a star with a binary companion can also have its evolution influenced by the companion. Multiple star systems can exist stably for millions of years, but can ultimately become unstable as one star grows in radius until it engulfs another. This volume, first published in 2006, discusses the statistics of binary stars; the evolution of single stars; and several of the most important kinds of interaction between two (and even three or more) stars. Some of the interactions discussed are Roche-lobe overflow, tidal friction, gravitational radiation, magnetic activity driven by rapid rotation, stellar winds, magnetic braking and the influence of a distant third body on a close binary orbit. A series of mathematical appendices gives a concise but full account of the mathematics of these processes.

James Binney, Michael Merrifield
R2,518 R2,351 Discovery Miles 23 510 Save R167 (7%) Ships in 12 - 17 working days

This is the definitive treatment of the phenomenology of galaxies--a clear and comprehensive volume that takes full account of the extraordinary recent advances in the field. The book supersedes the classic text Galactic Astronomy that James Binney wrote with Dimitri Mihalas, and complements Galactic Dynamics by Binney and Scott Tremaine. It will be invaluable to researchers and is accessible to any student who has a background in undergraduate physics.

The book draws on observations both of our own galaxy, the Milky Way, and of external galaxies. The two sources are complementary, since the former tends to be highly detailed but difficult to interpret, while the latter is typically poorer in quality but conceptually simpler to understand. Binney and Merrifield introduce all astronomical concepts necessary to understand the properties of galaxies, including coordinate systems, magnitudes and colors, the phenomenology of stars, the theory of stellar and chemical evolution, and the measurement of astronomical distances. The book's core covers the phenomenology of external galaxies, star clusters in the Milky Way, the interstellar media of external galaxies, gas in the Milky Way, the structure and kinematics of the stellar components of the Milky Way, and the kinematics of external galaxies.

Throughout, the book emphasizes the observational basis for current understanding of galactic astronomy, with references to the original literature. Offering both new information and a comprehensive view of its subject, it will be an indispensable source for professionals, as well as for graduate students and advanced undergraduates.

I have spent many wonderful nights observing at a variety of places around the world, but many of my fondest memories come from those made at the Custer Observatory in Southold on Long Island, where I grew up. I was only perhaps a dozen years old when I started out, and now more than three decades later I have logged millions of miles on the various telescopes there. Some of the best memories are of observing and discussing astronomical topics with the many really terrific people who make up Custer. It truly holds a special place in my heart. Star clusters were always among my favorite objects to observe and discuss there. This book is the result of the exposure to these objects, many of which I observed for the first time at Custer. The Custer Institute Observatory was founded in the 1920s by local resident Charles W. Elmer of Perkin-Elmer Corp. fame. The original crew met at his house in Cedar Beach a few miles down the road from the institute. In the 1930s the group built an observatory complete with Mr. Elmer's donated 5" Alvan Clark refractor. Later the observatory expanded to include a 6" Clark refractor and other even larger instruments.

R1,287 Discovery Miles 12 870 Ships in 12 - 17 working days

The stars that form a halo around our Galaxy are intriguing; they have abundances of elements that suggest they are old. The properties of these 'hot stars' and similar stars in other galaxies challenge the well-established theory of stellar evolution in many ways. Studying the collective properties of these stars provides important input to many areas of astrophysics - including the formation of our Galaxy, stellar evolution and the stellar populations of other galaxies. The study of hot stars in the halo of our Galaxy is undergoing an exciting renaissance owing to important new observations with the Hubble Space Telescope and ASTRO1 and to techniques recently developed for ground-based observations. Advances in computers have also recently led to a far more detailed and complete theoretical understanding of stellar evolution. This volume, first published in 1994, draws together the proceedings of a conference held in Union College, New York, which gathered experts in the field in question.

The Stars - Their Structure and Evolution (Paperback, 2 Rev Ed): Roger John Tayler The Stars - Their Structure and Evolution (Paperback, 2 Rev Ed)
Roger John Tayler
R1,397 Discovery Miles 13 970 Ships in 12 - 17 working days

This textbook gives a clear account of the manner in which knowledge in many branches of physics, such as gravitation, thermodynamics, atomic physics, and nuclear physics, can be combined to gain an understanding of the structure and evolution of stars. A major aim is to present the subject as one in which advances are still being made. The first half is an account of the observational properties of stars and a discussion of the equations that govern their structure. The second part discusses recent theoretical work on stellar evolution. The successes of the theory are stressed, but attention is also drawn to phenomena that are not completely understood. This is a new edition of a widely-used textbook first published in 1970. New topics include mass loss from stars and close binary stars.

Extreme Stars - At the Edge of Creation (Paperback): James B. Kaler Extreme Stars - At the Edge of Creation (Paperback)
James B. Kaler
R954 Discovery Miles 9 540 Ships in 12 - 17 working days

Over the past 200 years, our knowledge of stars has expanded enormously. From seeing myriad dots of different brightnesses, we haved moved on to measure their distances, temperatures, sizes, chemical compositions, and even ages, finding both young and ancient stars that dwarf our Sun and are dwarfed by it. Unique in its approach, Extreme Stars describes the lives of stars from a new perspective by examining their amazing features. The result is a refreshing, up-to-date, and engaging overview of stellar evolution, suitable for everyone interested in viewing or studying the stars. Ten chapters, generously illustrated throughout, explain the natures of the brightest, the largest, the hottest, and the youngest, among other kinds of stars, ending with a selection of the strangest stars the Universe has to offer. Extreme Stars shows how stars develop and die and how each extreme turns into another under the inexorable twin forces of time and gravity. James B. Kaler is Professor of Astronomy at the University of Illinois, Champaign-Urbana. He has held Fulbright and Guggenheim Fellowships, has been awarded medals for his work from the University of Liege in Belgium and the University of Mexico, and most recently was selected to give the Armand Spitz lecture by the Great Lakes Planetarium Association. His research area, in which he has published over 100 papers, involves dying stars. Kaler has also written for a variety of popular magazines, including Astronomy, Sky & Telescope, and Scientific American. His previous books include The Ever-Changing Sky (Cambridge, 1996), Stars and their Spectra (Cambridge, 1997), Cosmic Clouds (Scientific American Library Paperback, 1998), and The Little Book of Stars (Copernicus, 2000). He is a current member of the Board of Directors of the Astronomical Society of the Pacific and is a frequent guest on radio and television shows.

Photographs of Stars, Star-Clusters and Nebulae - Together with Information Concerning the Instruments and the Methods Employed in the Pursuit of Celestial Photography (Paperback)
Isaac Roberts
R901 Discovery Miles 9 010 Ships in 12 - 17 working days

A geologist and fellow of the Royal Astronomical Society, Isaac Roberts (1829 1904) made significant contributions to the photography of star-clusters and nebulae. By championing reflecting rather than refracting telescopes, Roberts was able to perceive previously unnoticed star-clusters, and was the first to identify the spiral shape of the Great Andromeda Nebula. Roberts' use of a telescope for photographing stars, and a long exposure time, provided greater definition of stellar phenomena than previously used hand-drawings. Although Roberts' conclusions about the nature of the nebulae he photographed were not always correct, the book is significant for the possibilities it suggests for nebular photography. Published in London in 1893 and 1899, the two-volume Photographs of Stars represents the summation of his work with his assistant W. S. Franks at his observatory in Crowborough, Sussex. Volume 1 contains 51 collotype plates of stars, and descriptions of his instruments and methods.

R718 Discovery Miles 7 180 Ships in 12 - 17 working days

Admiral William Henry Smyth's Sidereal Chromatics (1864) represents a landmark achievement in nineteenth-century astronomy, offering the most precise observations of the colours of double stars yet recorded. An expansion upon his well-known Bedford Cycle of Celestial Objects, which garnered a gold medal from the Royal Astronomical Society, Sidereal Chromatics provides both a theory concerning the source of double-star colours and a method for determining their most exact description. Detailed charts compare Smyth's measurements of more than one hundred double stars with his own previously published observations and those of his fellow astronomer, Father Benedetto Sestini. This edition also includes Smyth's famous colour chart, an attempt to standardise the process of identifying double-star colours. Sidereal Chromatics ends with Smyth's plea to amateur astronomers to continue the effort of charting the heavens, aided by improved telescopes and works such as his, 'trustworthy treatises available to all men'.
