Abundance analyses of theta Aquilae (B9.5III), nu Capricorni (B9.5V), and sigma Aquarii (A0IVs).
Abstract
Abundance analyses for three moderately sharp-lined stars with spectral types near AO Theta Aql, Nu Cap, and Sigma Aqr have been performed via model atmospheres techniques. The derived abundances of the first two stars are quite similar to those of the sun and other normal main-sequence stars. Those of Sigma Aqr suggest that this star is a hot metallic-line star.
