Abstract:
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.
