Download or read book The Milky Way as a Galaxy written by Gerry Gilmore and published by . This book was released on 1990 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a comprehensive view of Galactic astronomy, written from a global point of view. The three authors have collaborated to produce a new synthesis of the forefront of knowledge about our Galaxy - what it is, what is in it, and how it might have come to be that way. The book consists of 16 chapters that cover the structure and dynamics of the Milky Way; the nature, distribution, and possible origin of its various populations; and its relationship to other galaxies. The level of the book is suitable for working astronomers, graduate students, advanced undergraduates, and knowledgeable amateurs.
Download or read book Astrophysik II Sternaufbau Astrophysics II Stellar Structure written by Marshal H. Wrubel and published by Springer. This book was released on 1958-01-02 with total page 832 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sects. 12, 13. 89 sequence and that subgiant and fainter stars in globular clusters have ultraviolet excesses. When dealing with stars whose physical properties are imperfectly under stood, such as in globular cluster stars, we cannot rely too heavily on the empiri cal calibration by the kinds of stars used to define Fig. 5, to determine their true, unreddened U-B, B-V curve. But if by a combination of arguments, principally the reddening in the region of the stars we do known about, we can assign a fairly probable unreddened U-B, B-V curve to a group of stars about which we know little, the argument may be turned around. In this case some information may be gained about the energy envelope of the stars by examining the differences between the normal two-color index curves for the unknown group of stars compared to the known. In general there seem to be two possible causes for different stars defining different normal sequences in the U-B, B-V plane. One, the relative energy distribution in the continuum in the U, B and V photometry bands are different. An example of this is the effect of the Balmer depression in supergiants. This, of course, requires deviation from black body radiation curves for one or both groups of stars. This cause seems to be the dominant effect for very blue, hot stars where the depression of the continuum by absorption lines is at a minimum.
Download or read book Principles of Stellar Dynamics written by S. Chandrasekhar and published by Courier Corporation. This book was released on 2005-05-13 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this classic text, a Nobel Prize-winning astrophysicist presents the theory of stellar dynamics as a branch of classical dynamics--a discipline in the same general category as celestial mechanics. His method offers the advantages of clarifying the theory's fundamental issues and defining its underlying motivations. S. Chandrasekhar investigates two areas. The first concerns problems in which the time of relaxation of a stellar system is central. His method consists of analyzing the effects of stellar encounters in terms of the two-body problem of classical dynamics and applying this theory to the dynamics of star clusters. The second area investigates problems centering around Liouville's theorem and the solutions of the equation of continuity; here, the author discusses the dynamic implications of the existence of a field of differential motions, which appears to be the most striking kinematic feature of the galaxy and the extragalactic systems. This edition includes two papers by the author that were published after Principles of Stellar Dynamics and that have been studied and quoted extensively: "New Methods in Stellar Dynamics" (originally published in the Annals of the New York Academy of Sciences) and "Dynamical Friction" (originally published in The Astrophysical Journal).

Download or read book Astrophysics Is Easy written by Michael Inglis and published by Springer. This book was released on 2014-12-04 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Astrophysics is often –with some justification – regarded as incomprehensible without the use of higher mathematics. Consequently, many amateur astronomers miss out on some of the most fascinating aspects of the subject. Astrophysics Is Easy! cuts through the difficult mathematics and explains the basics of astrophysics in accessible terms. Using nothing more than plain arithmetic and simple examples, the workings of the universe are outlined in a straightforward yet detailed and easy-to-grasp manner. The original edition of the book was written over eight years ago, and in that time, advances in observational astronomy have led to new and significant changes to the theories of astrophysics. The new theories will be reflected in both the new and expanded chapters. A unique aspect of this book is that, for each topic under discussion, an observing list is included so that observers can actually see for themselves the concepts presented –stars of the spectral sequence, nebulae, galaxies, even black holes. The observing list has been revised and brought up-to-date in the Second Edition.

This book was released on 2017-11-30 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This joint venture between ICOMOS, the advisory body to UNESCO on cultural sites, and the International Astronomical Union is the second volume in an ongoing exploration of themes and issues relating to astronomical heritage in particular and to science and technology heritage in general. It examines a number of key questions relating to astronomical heritage sites and their potential recognition as World Heritage, attempting to identify what might constitute "outstanding universal value" in relation to astronomy. "Heritage Sites of Astronomy and Archaeoastronomy--Volume 2" represents the culmination of several years' work to address some of the most challenging issues raised in the first ICOMOS-IAU Thematic Study, published in 2010. These include the recognition and preservation of the value of dark skies at both cultural and natural sites and landscapes; balancing archaeoastronomical considerations in the context of broader archaeological and cultural values; the potential for serial nominations; and management issues such as preserving the integrity of astronomical sightlines through the landscape.Its case studies are developed in greater depth than those in volume 1, and generally structured as segments of draft nomination dossiers. They include seven-stone antas (prehistoric dolmens) in Portugal and Spain, the thirteen towers of Chankillo in Peru, the astronomical timing of irrigation in Oman, Pic du Midi de Bigorre Observatory in France, Baikonur Cosmodrome in Kazakhstan, and Aoraki-Mackenzie International Dark Sky Reserve in New Zealand. A case study on Stonehenge, already a World Heritage Site, focuses on preserving the integrity of the solstitial sightlines.As for the first ICOMOS-IAU Thematic Study, a international team of authors including historians, astronomers and heritage professionals is led by Professor Clive Ruggles for the IAU and Professor Michel Cotte for ICOMOS.
Download or read book A Reference Catalogue and Atlas of Galactic Novae written by Hilmar W. Duerbeck and published by Springer Science & Business Media. 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.
