The double-lined spectroscopic binary alpha Andromedae: orbital elements   and elemental abundances
  We performed a spectroscopic study of the SB2 Mercury-Manganese star alpha And. Our measurements of the secondary's radial velocities result in improved orbital elements. The secondary shows abundances typical of the metallic-line stars: a Ca deficiency, small overabundances of the iron-peak elements, and 1.0 dex overabundances of Sr and Ba.
