A Spectroscopic Study of the Pleiades.
Abstract
A spectroscopic study of 78 stars of the Pleiades has been made. Spectra of 59 members are combined with the photoelectric observations of Johnson. After eliminating the effects of interstellar absorption, a two-color diagram and an H-R diagram were constructed. The discontinuity in the color index (B - V) sh6wn by the near-by stars is not present in the Pleiades. The F stars in the Pleiades appear, on the average, to be relatively fainter in the ultraviolet than stars of similar type and luminosity in the neighborhood of the sun
