Astrometric Techniques
Proceedings of the 109th Symposium of the International Astronomical Union, held in Gainesville, Florida, USA, January 9-12, 1984
Understanding the Heavens
From its beginnings, astronomy has attempted to explain not only what the universe is and how it works, but also its origins, evolution, and future. Richly illustrated, this book traces astronomical thought from Egypt, Mesopotamia and Greece, through the European golden age of Copernicus, Galileo, Kepler and Newton, and up to the latest modern theories of cosmology.
Interplanetary Astrodynamics
Focusing on the orbital mechanics tools and techniques necessary to design, predict, and guide a trajectory of a spacecraft traveling between two or more bodies in a Solar System, this book covers the dynamical theory necessary for describing the motion of bodies in space, examines the N-body problem, and shows applications using this theory for designing interplanetary missions. While most orbital mechanics books focus primarily on Earth-orbiting spacecraft, with a brief discussion of interplanetary missions, this book reverses the focus and emphasizes the interplanetary aspects of space missions. Written for instructors, graduate students, and advanced undergraduate students in Aerospace and Mechanical Engineering, this book provides advanced details of interplanetary trajectory design, navigation, and targeting.
Astrometry of Fundamental Catalogues
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.
Comets
Over forty authorities present sections on the nucleus, dust, coma, and tails of comets, along with sections on their origin, and relationships to other solar system bodies. . . . An excellent book.ÑSpace News "The volume is highly recommended to all interested in comets and the Solar System."ÑJournal of the British Astronomical Association "A good representation of the studies that are currently being done on comets, and it is an extremely good source of information on a wide variety of topics."ÑInternational Comet Quarterly "Extremely well-written and informative. . . . A must for library collections."ÑThe Observatory
The Evolution of Galaxies
Galaxies have a history. This has become clear from recent sky surveys which have shown that distant galaxies, formed early in the life of the Universe, differ from the nearby ones. New observational windows at ultraviolet, infrared and millimetric wavelengths (provided by ROSAT, IRAM, IUE, IRAS, ISO) have revealed that galaxies contain a wealth of components: very hot gas, atomic hydrogen, molecules, dust, dark matter ... A significant advance is expected due to new instruments (VLT, FIRST, XMM) which will allow one to explore the most distant Universe. Three Euroconferences have been planned to punctuate this new epoch in galactic research, bringing together specialists in various fields of Astronomy.
