Ultraviolet television data from the orbiting astronomical observatory. II - Stellar ultraviolet colors and interstellar extinction
The results from the Celescope Catalog of Ultraviolet StellarObservations (Davis, Deutschman, and Haramundanis 1973) are studied,emphasizing statistical groups and subgroups of stars. In spite of therather large observational errors, the great number of Celescopeobservations make it possible to do that kind of study with reasonableaccuracy. Some stars have ultraviolet colors that differ significantlyfrom those of the group to which they have been assigned on the basis ofground-based observations. An attempt is made to describe the generalproperties of the ultraviolet colors of the stars as observed by theCelescope experiment on board NASA's Orbiting Astronomical Observatory(OAO-2). Besides the direct applicability of these results to thegeneral study of stellar atmospheres and of interstellar extinction,they are also considered as a frame of reference for further studies ofindividual stars and groups of stars.
