Spectrophotometric Studies of Faint Astronomical Sources with Image Tubes.

摘要

The Robinson-Wampler image tube scanner,the Beaver-Digicon and direct coupled electrostatic image tubes are used as spectrophotometric detectors to study a variety of objects including a quasi-stellar source,extra galactic planetary nebulae,galactic planetary nebulae and H alpha emission line stars in the Large Magellanic Cloud. Direct coupled electrostatic image tubes are applied to a survey of the infrared component of Cygus OB2and to the search for planetary nebulae in Local Group elliptical galaxies. A compilation of specific results is cited in the literature. (Author)
