Download or read book Introduction to Astronomical Photometry written by M. Golay and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: The material given in this 'Introduction to astronomical photometry' is the subject matter of a lecture at the University of Geneva. It is, therefore, intended for those students, physicists or mathematicians, who have completed their bachelor's degree or diploma, and are intending to work for their Ph.D. in astronomy. We assume then the elementary ideas of astrophysics, magnitude, colour index, spectral classes, luminosity classes, gradient, atmospheric extinction are already known. The student may find it useful to re-read the work of Schatzman [1], Dufay [2] and Aller [254] before embarking upon the study of this 'Introduction to astronomical photometry'. It is not our aim in this book to deal with every aspect of stellar photometry. On the contrary, we shall restriet ourselves to looking at subjects ofwhich knowledge seems to us essential for someone who has to use photometrie quantities in his astronomical research. We are, therefore, keeping the interests of the photometrie measurements user partieularly in mind. We shall only discuss very superficially the technical prob lems and reduction methods for atmospheric extinction. These problems are dealt with very clearly in Astronomical Techniques [3]; the first by A. Lallemand, H. L.

Download or read book Literature 1969 Part 2 written by Siegfried Böhme and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: Astronomy and Astrophysics Abstracts, which appears in semi-annual volumes, is devoted to the re cording, summarizing and indexing of astronomical publications throughout the world. It aims to pre sent a comprehensive documentation of literature in all fields of astronomy and astrophysics. Every effort will be made to ensure that the average time interval between the date of receipt of the original literature and publication of the abstracts will not exceed eight months. This time interval is near to that achieved by monthly issued abstracting journals, compared to which our system of accumulating abstracts for about six months offers the advantage of greater convenience for the user. Volume 2 contains literature published in 1969 and received before March 15, 1970; some older lite rature which was received late and which is not recorded in Volume 1 is also included. The authors of papers who have sent us abstracts on request have effectively contributed to the suc cess of our service. We should like to express our gratitude to them. We acknowledge with thanks con tributions to this volume by Dr. J. Bou~a, who surveyed journals and publications in Czech language and supplied us with abstracts in English, by Dr. B. Onderlicka, Brno, for providing English ab stracts of Russian papers, and by the Commonwealth Scientific and Industrial Research Organization (C.S.I.R.O.), Sydney, for providing titles and abstracts of papers on radio astronomy.

This book was released on 2013-12-01 with total page 1390 pages. Available in PDF, EPUB and Kindle. Book excerpt: This catalog contains data on the magnitudes of more than 100,000 stars in the Galaxy. For each star listed, the catalog gives the position, identification, and ultraviolet, blue and visual magnitude from photoelectric measurements. The measurements from which these mean values were computed were collected from observations published between 1953 and 1992. The volume includes more than 1400 references.

Available in PDF, EPUB and Kindle. Book excerpt: Astronomy and Astrophysics Abstracts, which has appeared in semi-annual volumes since 1969, is de voted to the recording, summarizing and indexing of astronomical publications throughout the world. It is prepared under the auspices of the International Astronomical Union (according to a resolution adopted at the 14th General Assembly in 1970). Astronomy and Astrophysics Abstracts aims to present a comprehensive documentation of Iiterature in all fields of astronomy and astrophysics. Every effort will be made to ensure that the average time interval between the date of receipt of the original Iiterature and publication of the abstracts will not exceed eight months. This time interval is near to that achieved by monthly abstracting journals, com pared to which our system of accumulating abstracts for about six months offers the advantage of greater convenience for the user. Valurne 7 contains Iiterature published in 1972 and received before August 15, 1972; some older Iiter ature which was received late and which is not recorded in earlier volumes is also included.

Download or read book Deep Sky Companions Southern Gems written by Stephen James O'Meara and published by Cambridge University Press. This book was released on 2013-04-08 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Southern Gems, Stephen James O'Meara makes a detour beneath the southern skies, presenting a fresh list of 120 deep-sky objects for southern hemisphere stargazers to observe. Showcasing many exceptional objects catalogued by the pioneering observer James Dunlop, known as the 'Messier of the southern skies', all are visible through small- to moderate-sized telescopes or binoculars under dark skies. The list features some of the blackest dark nebulae, icy blue planetary nebulae and magnificent galaxies of all types. Each object is accompanied by beautiful photographs and sketches, original finder charts, visual histories and up-to-date astrophysical background information. Whether you live in the southern hemisphere or are just visiting, this new Deep-Sky Companion will make a perfect observing partner, whatever your background. There is no other southern sky guide like it on the market.
