This book was released on 2013-03-09 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: 4. Census of the Catalogue The catalogue contains information on 277 objects. 137 (50%) of them are stars whose outburst spectra or unambiguous mInImUm characteristics classify them as novae beyond doubt. 123 of them could be identified at minimum. 78 (28 %) are stars with amplitudes and light curve forms which makes nova classifi cation likely. 60 of them could be identified at minimum. Thus, 78 % ofthe objects in this catalogue are confirmed and suspected classical novae. 16 (6%) have properties compatible with both novae and related objects. 15 are identified at minimum. Furthermore, the catalogue and atlas contains data on 12 (4 %) dwarf novae of long cycle length or suspected dwarf novae for which only one outburst has been observed. Examples are WZ Sge and CI Gern. 6 (2%) recurrent novae or suspected recurrent novae are listed. Examples are T CrB and AS Psc. 6 (2%) X-ray novae are listed. Examples are V616 Mon and KY TrA. 6 (2%) symbiotic stars and symbiotic novae are listed. Examples are RT Ser and V352 Aql. 11 (4 %) Mira stars or suspected Mira stars, which at some time were believed to be novae, are listed. Examples are V607 Aql and V927 Sgr.

This book was released on 2009-03-01 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the Victorian era – or for non-British readers, the mid-to-late nineteenth century – amateur astronomy tended to center on Solar System objects. The Moon and planets, as well as bright comets, were the key objects of interest. The brighter variable stars were monitored, but photography was in its infancy and digital imaging lay a century in the future. Today, at the start of the twenty-first century, amateurs are better equipped than any professionals of the mid-twentieth century, let alone the nineteenth. An amateur equipped with a 30-cm telescope and a CCD camera can easily image objects below magnitude 20 and, from very dark sites, 22 or 23. Such limits would have been within the realm of the 100- and 200-inch reflectors on Mount Wilson and Mount Palomar in the 1950s, but no other observatories. However, even those telescopes took hours to reach such limits, and then the photographic plates had to be developed, fixed, and examined by eye. In the modern era digital images can be obtained in minutes and analyzed ‘on the fly’ while more images are being downloaded. Developments can be e-mailed to other interested amateurs in real time, during an observing session, so that when a cataclysmic event takes place amateurs worldwide know about it. As recently as the 1980s, even professional astronomers could only dream of such instantaneous communication and proc- sing ability.

Download or read book Applied and Computational Historical Astronomy Angewandte und computergest tzte historische Astronomie written by Gudrun Wolfschmidt and published by tredition. This book was released on 2021-08-26 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Computational History' derives history from data and nowadays, therefore, relies on the technologies of the digital humanities. 'Computational History of Science' addresses questions of history by evaluating historical data, e.g. for tracing back copying traditions and conclude on transfer and transformation of data and knowledge. The term 'Applied Historical Astronomy', in contrast, tries to address questions of contemporary science by evaluating historical data in comparison with most recent data. This opens new possibilities, e.g. in the search for stellar transients among historical data. In the contribution by Hoffmann & Vogt we will focus on the stellar transients among all the topics mentioned above. Philipp Protte discusses the accuracy of magnitudes and positions in ancient star catalogues, Andreas Schrimpf & Frank Verbunt present an analysis of an early modern star catalogue. Victor Reijs analyses the visibility of celestial objects for naked-eye observers, and Björn Kunzmann showcases some important variable stars in the history of astronomy. Rene Hudec presents astronomical photographic archives as a valuable data source for modern astrophysics. José M. Vaquero discusses the studies on solar observations made during the last four centuries. More technical are the contributions of Georg Zotti on Stellarium and Karsten Markus-Schnabel on data-mining and data-processing technologies. Ido Yavetz & Luca Beisel are developing a digital tool of computational history of science for the simulation of pre-modern astronomical models. Gerd Graßhoff focuses more on the application of computational history with regard to Kepler's Astronomia Nova while Tim Karberg presents an analysis of the astronomical orientation of buildings in the North Sudan.
Download or read book Astrophysical Data written by Kenneth R. Lang and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 942 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume of Astrophysical Data deals with Planets and Stars; a second volume, Part II, will give data for Galaxies and the Universe. They both pro vide basic data for use by all scientists, from the amateur astronomer to the professional astrophysicist. In this first volume, we not only provide physical parameters of planets, stars and their environment, but we also provide the celestial coordinates required to observe them. Here we use c.g.s. units, for they are the most commonly used in astron omy and astrophysics; but our volume begins with astronomical and physical constants and the conversion factors needed for other units. The next section concerns the planets and their satellites; it singles out the Earth and Moon for special treatment. Spacecraft rendezvous with the planets and satellites have led to improved values for their atmospheric compositions, orbital parameters, magnetic fields, masses, radii, rotation periods, and surface pressures and temperatures. This section also contains data for the asteroids, comets and their debris. We then discuss everyday stars, beginning with the Sun, and continuing with basic stellar data, the brightest stars and nearby stars. Special categories of stars, such as the Wolf-Rayet stars, magnetic stars, flare stars, and RS CVn binary stars, are included.
Download or read book Cataclysmic Variables written by A. Bianchini and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cataclysmic Variables (CVs) are well furnished laboratories in which one can investigate a number of important physical processes. These processes include: thermonuclear reactions, nebular physics, winds, mass accretion phenomena on compact objects, magnetohydrodynamics, plasmas, thermal and non thermal radiative processes, relativistic phenomena, dust forma tion, etc . . In the recent year the most exciting development in our opinion was that the small, cold and invisible secondary components of CV s were found to be the prime motors for the evolution of close binary systems, disclosing new scenarios for research. All branches of astronomy and as trophysics often take advantage of the new ideas brought by the study of CVs. It is for this reason, we believe, that meetings on CVs are important for most of the astronomical community. The idea of a Congress on CVs in Padova has been fluttering in the air for a few years. After all - we thought - a large part of the scientific heritage of Padova and Asiago Observatories is represented by the study of variable stars and, in particular, of CV s, as Prof. L. Rosino reminded us at the very beginning of the Congress. We finally chose Abano Terme as the site of the Conference, not merely because Abano is one of the most famous centers in Europe for mud therapy, and astronomers easily suffer from rheumatism, but also because we knew that a very hearty welcome from the Abano Municipality and touristic associations awaited us.

Download or read book Reviews in Modern Astronomy written by Gerhard Klare and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Scientific Spring Meeting of the Astronomische Ge sellschaft (AG) held at Bamberg in April 1991 was devoted to "Vari abilities in Stars and Galaxies". Time-dependent phenomena are observed in a wide range of as tronomical objects. They are caused by different physical mechanisms (for example by pulsation, by accretion, or by dramatic eruptive events in connection with mass outflow) producing observable intensity vari ations through all wavelengths. Many of the papers in this volume are concerned with galactic stars showing such behaviour (for ex ample cataclysmic variables, symbiotic stars, luminous blue variables (LBVs) and novae). Intrinsic variations of the, magnetic field struc ture on observable time scales are, for instance, a peculiarity of cool, solar-like stars and represent a useful tool to study differential rotation and cycles of activity. Recent results on the investigation of gas motions in the inner regions of the Milky Way system, a study of the bipolar galaxy M 82, observations of variable extragalactic radio sources, the variability of emission lines in active galactic nuclei (AGN) as well as continuum variations of quasars and AGN are discussed by several authors. The yearbook series Reviews in Modern Astronomy of the AG to bring the scientific events of the was established in 1988 in order meetings of the society to the attention of the worldwide astronomical community.
Download or read book Active Close Binaries written by Cafer Ibanogammalu and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 898 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the 1970s symposia or colloquia devoted to recent research on close binaries have been held around the world almost annually. At meetings of the General Assembly of the International Astronomical Union this topic has also been discussed in detail at presentations in various commission meetings and also as invited talks by leading astronomers in the field. In recent years, fundamental changes have taken place in the study of close binaries due to the improvements in observational techniques, extension of observations from X-ray to radio regions of the electromagnetic spectrum, and advances in theoretical studies. For more than a decade, a group of astronomers at Ege University Observatory has been concentrating on active close binaries with particular emphasis on the behaviour of the light curves of chromospherically active systems. Thus, we decided to organize an international meeting in Western Anatolia, where this part of Turkey had been the cradle for great developments in science during antiquity. KUljadasi, located only minutes away from Ephesus, one of the seven wonders of the world, was selected to be the meeting site. Close binary systems constitute a very rich source of information about the physical properties of the component stars. Some systems are eclipsing variables, where periodic recurrences of eclipses are observed as comparatively brief decreases in the total brightness of the binary system. Precise methods of photometric observations make it possible to obtain the light variations of these systems because of eclipses and other phenomena.
Download or read book Accretion powered Compact Binaries written by Christopher W. Mauche and published by Cambridge University Press. This book was released on 2003-12-04 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a well-edited and comprehensive survey of the current research in the field of low-mass accretion powered compact binaries, that is, binary stars containing a white dwarf, neutron star, or black hole as the primary star and a Roche-lobe filling low-mass as the secondary star. These stars have reached a stage in their evolution where the transfer of mass from the giant phase onto a dwarf or sub-dwarf star demonstrates many different aspects of physics. The volume is essentially a complete analysis of these stars combining theory and observation, and covering observations of low-mass X-ray binaries and both magnetic and nonmagnetic cataclysmic variables, theories of stellar accretion, novae, and evolution of compact binaries.
Download or read book X ray Binaries written by Walter H. G. Lewin and published by Cambridge University Press. This book was released on 1997-01-16 with total page 688 pages. Available in PDF, EPUB and Kindle. Book excerpt: X-ray binaries are some of the most varied and perplexing systems known to astronomers. The compact object which accretes mass from its companion star may be a white dwarf, neutron star, or black hole, whereas the donor star can be a 'normal' star or a white dwarf. The various combinations differ widely in their behaviour, and this timely volume provides a unique reference of our knowledge to date of all of them.Fifteen specially written chapters by a team of the world's foremost researchers in the field explore all aspects of the X-ray binaries. They cover the X-ray, ultraviolet, optical and radio properties of these violent systems and address key issues such as: how were these systems formed, and what will be their fate; how can we understand X-ray bursts, and how the quasi-periodic oscillations; what is the connection between millisecond radio pulsars and low-mass X-ray binaries; and how does the magnetic field of a neutron star decay?This long awaited review provides graduate students and researchers with the standard reference on X-ray binaries for many years to come.
