Stellar Photometry: Current Techniques and Future Developments: IAU Colloquium 136

Front Cover
Stellar photometry deals with the accurate measurement of light from stars and galaxies. It is one of the principal tools of the astronomer and is used in the determination of the brightness, radius and temperature of stars, and, increasingly, in the study of their atmospheres and interiors. The book contains the proceedings of a colloquium held in Dublin in August 1992 that reviewed the most recent developments in stellar photometry and the many technical problems that face photometrists in their quest for ever more accurate and meaningful data. This book covers the following topics: (1)Photometric systems; including the pros and cons of rival photometric systems and how they are affected by choice of detector and equipment design; (2)High precision photometry; the factors that limit the routine attainment of millimagnitude accuracy both in measurement and conversion to a standard system; (3)New techniques in photometry, using multichannel arrays in the optical and infrared regions; (4)Automatic photoelectric telescopes and the setting up of global networks to provide continuous photometric coverage; (5)Photometry with CCDs, and (6)Photometry from instruments in space or on the Moon.
