Available in PDF, EPUB and Kindle. Book excerpt: This program was aimed at understanding the number and types of sources found in the fields observed with greatest sensitivity by the IRAS satellite. The initial phase of the study emphasized observation and analysis of sources found in the less sensitive all sky survey carried out with Infrared Astronomy Satellite. Significant differences between the bright and faint 12 um sources were found, which constrain their relative spatial distributions and luminosities. A study focussed one one, large population of infrared-bright stars -- those whose atmospheres are rich in carbon - yielded measurements of their space distribution range of mass loss rates, and lifetimes. An analysis of 60 um sources from the IRAS survey showed that eighty-five percent of those located more than thirty degrees above the plane of the Galaxy are extragalactic objects, provided a measure of the space density of galaxies of different infrared luminosities, and showed that there are significant differences in the environment and infrared properties of the most luminous and least luminous galaxies. Studies of galaxies with particularly strong mid-infrared emission resulted in the discovery of ultraluminous objects. Initial studies of results from the IRAS pointed observations show effects of contamination by low-surface-brightness intestellar clouds.

This book was released on 1991 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results are presented of studies of the space distribution and other properties of two significant classes of compact astrophysical sources which are bright at midinfrared wavelengths: stars with excess infrared emission due to heated dust, and galaxies with nuclei that heat surrounding dust to anomalously high temperatures. The stellar studies reveal a complex structure for the galactic disk, which must be taken into account in the development of realistic infrared sky models. The extragalactic studies have been temporarily stalled by the remarkable discovery of low-luminosity stars with strong far-infrared spectral energy distributions mimicking warm galaxies Much further observational work is needed to understand the origin of this emission.

Available in PDF, EPUB and Kindle. Book excerpt: The development of deep space surveillance technology and its later application to near-Earth surveillance, covering work at Lincoln Laboratory from 1970 to 2000. In the 1950s, the United States and the Soviet Union raced to develop space-based intelligence gathering capability. The Soviets succeeded first, with SPUTNIK I in 1957. The United States began to monitor the growing Soviet space presence by developing technology for the detection and tracking of man-made resident space objects (RSOs) in near-Earth orbit. In 1972, the Soviet Union launched a satellite into deep space orbit, and the U.S. government called on MIT Lincoln Laboratory to develop deep space surveillance technology. This book describes these developments, as well as the later application of deep space surveillance technology to near-Earth surveillance, covering work at Lincoln Laboratory on space surveillance from 1970 to 2000. The contributors, all key participants in developing these technologies, discuss topics that include narrow beam, narrow bandwidth radar for deep surveillance; wide bandwidth radar for RSO monitoring; ground-based electro-optical deep space surveillance and its adaptation for space-based surveillance; radar as the means of real-time search and discovery techniques; methods of analyses of signature data from narrow bandwidth radars; and the collision hazard for satellites in geosynchronous orbit, stemming initially from the failure of TELSTAR 401. They also describe some unintended byproducts of this pioneering work, including the use of optical space surveillance techniques for near-Earth asteroid detection.

Available in PDF, EPUB and Kindle. Book excerpt: IAU Transactions are published as a volume corresponding to each General Assembly. Volume A is produced prior to the Assembly and contains Reports on Astronomy, prepared by each Commission President. The intention is to summarize the astronomical results that have affected the work of the Commission since the production of the previous Reports up to a time which is about one year prior to the General Assembly. Volume B is produced after the Assembly and contains accounts of Commission Meetings which were held, together with other material. The reports included in the present volume range from outline summaries to lengthy compilations and references. Most reports are in English.

Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1981, the completely revised and updated second edition of the Dictionary of Space Technology illustrates the advances of the last 20 years and makes accessible nearly every word, concept, and event relating to this branch of science. It guides lay persons and professionals alike through humankind's activities in space, the beginnings of our extraterrestrial society, and the increasingly important role of space sciences in everyday life. Defines more than 1,500 terms, including: science basics; historic events; defence and armed forces terminology; and planetary sciences. Enhanced by more than 175 photographs and drawings, this Dictionary covers the past, the present and the future of space, space flight, and space technology.

Available in PDF, EPUB and Kindle. Book excerpt: Astronomy and Astrophysics Abstracts aims to present a comprehensive documen tation of the literature concerning all aspects of astronomy, astrophysics, and their border fields. It is devoted to the recording, summarizing, and indexing of the relevant publications throughout the world. Astronomy and Astrophysics Abstracts is prepared by a special department of the Astronomisches Rechen-Institut under the auspices of the International Astronomical Union. Volume 33 records literature published in 1983 and received before August 1, 1983. Some older documents which we received late and which are not surveyed in earlier volumes are included too. We acknowledge with thanks contributions of our colleagues all over the world. We also express our gratitude to all organizations, observatories, and publishers which provide us with complimentary copies of their publications. Starting with Volume 33, all the recording, correction, and data processing work was done by means of computers. The recording was done by our technical staff members Ms. Helga Ballmann, Ms. Mona El-Choura, Ms. Monika Kohl, and Ms. Sylvia Matyssek. Mr. Martin Schlotelburg and Mr. Ulrich Uberall supported our task by careful proofreading. It is a pleasure to thank them all for their encouragement.
