ULTRAVIOLET SPECTRA OF FIELD HORIZONTAL-BRANCH A-TYPE STARS. II

The spectra of six additional A-type stars have been obtained at low resolution between λ 1200 and λ 1900 with the International Ultraviolet Explorer (IUE). The energy distributions of four of the stars match that of the "FHB" distribution in Huenemoerder et al. (1984) while those of the o...

More Information
Summary:The spectra of six additional A-type stars have been obtained at low resolution between λ 1200 and λ 1900 with the International Ultraviolet Explorer (IUE). The energy distributions of four of the stars match that of the "FHB" distribution in Huenemoerder et al. (1984) while those of the other two do not. Three of the FHB stars fall above a line in the (19 — V)₀ vs. (b — y)₀ diagram; however, HD 60825 is anomalously blue for its (19 — V) color.
