An introduction to practical astrometry, dealing with the determination of positions, motions, distances and dimensions of celestial bodies ranging from quasars to artificial satellites. For this 2nd edition, the release of the Hipparcos and Tycho catalogs, the rise in CCD astrometry and the adoption of a new celestial reference frame by the IAU led to a significant modification of the text. And, especially, the outlook for astrometry has been completely rewritten.

This is a definitive reference of 2,100 fundamental formulae used in astronomy and astrophysics. It not only makes accessible all the indispensable equations employed in the field, but also carefully explains the physical assumptions and constants underlying them. The bibliography contains more than 1,900 citations of original papers. Accounting for nearly 20 years since the previous edition, this volume is significantly revised and expanded.

The book "Relativity in Astrometry, Celestial Mechanics and Geodesy" repre sents a significant contribution to modern relativistic celestial mechanics and astrometry. In these branches of astronomy the theory of general relativity is used nowadays as an efficient practical framework for constructing accurate dynamical theories of motion of celestial bodies and discussing high-precision observations. The author develops the useful tools for this purpose and intro duces the reader into the modern state of the art in these domains. More specifically, the distinctive feature of the book is the wide application of the tetrad formalism to astronomical problems. One may not agree with the author's opinion that this is the only method so far to be able to treat the rel ativistic astronomical problems in a consistent and satisfactory manner. (On the contrary, one may foresee in the nearest future other books on relativistic celestial mechanics and astrometry based on different approaches solving the same problems. ) However, we are now at the beginning of practical relativis tic astronomy and it will demand much effort to reconstruct in a relativistic manner all Newtonian conceptions of ephemeris astronomy and geodesy. In particular, this concern. s the definitions of reference frames, time scales and astronomical units of measurement. This book is one of the first steps in the correct direction. V. A.

Celestial fundamental catalogues are a prerequisite for the determination of absolute positions and motions in space. Presently, positional astrometry is at the watershed between classical fundamental catalogues, based on moving reference stars, and modern catalogues, based on extragalactic reference objects with non-measurable motion. This book addresses the concepts and methods of the respective construction techniques leading to the stellar frame of the FK5 (fifth fundamental catalogue) and to the newly adopted extragalactic radio reference frame, ICRF (international celestial reference frame), with its extension to optical wavelengths by the Hipparcos Catalogue. While principal outlines of meridian circle observations are given, emphasis is put in some detail on the VLBI technique as applied to astrometry, and to the observational techniques used in the Hipparcos mission, including the tie of the originally non-anchored rigid Hipparcos sphere into the ICRF.

Providing a comprehensive and clear account of the instruments and techniques used in modern astronomy and astrophysics, the fourth edition of Astrophysical Techniques continues to offer information on all astronomical observations. Retaining the aims of earlier editions, the author unifies the concepts through lucid language and cohesive organization of the book. Revised and updated, this book encompasses an ever-diverging array of observational techniques using the detection-imaging-ancillary instruments pattern. The first several sections emphasize the detection of radiation or other information carrier as well as the instruments and techniques used to facilitate and optimize that detection. Later chapters discuss photometers and spectroscopes in detail while also examining the techniques of astrometry, polarimetry, and magnetometry. New to the Fourth Edition: Many instruments and techniques included for the first time A section that supplies Web sites and online resources Elimination of archaic topics, providing the most up-to-date information available Astrophysical Techniques, Fourth Edition maintains comprehensive coverage of the instruments and techniques used in current astronomy and astrophysics, making it a superb reference for undergraduate and postgraduate students in astronomy, amateur astronomers, and professional astronomers.
