Far ultraviolet photometry of intermediate brightness stars from Apollo-Soyuz.
Abstract
We present photoelectric photometry in the 1350-1600 A band of 52 stars of intermediate brightness, using data obtained in 1975 July with a grazing incidence telescope aboard the Apollo-Soyuz Test Project. Upper or lower limits on the brightness of 106 additional objects which were spatially blended with one or more companions were also obtained. The data sample consists of stars with V not greater than 7.5 and spectral types from O6 through A5. When corrected for interstellar extinction, the ultraviolet photometry on a two-color diagram agrees very well with the predictions of the revised blanketed model atmospheres by Kurucz. Attention is also drawn to an anomalously UV-bright object which is probably associated with HD 100493.
