| 英文摘要 | On the basis of high-resolution echelle spectra obtained with the Coude Echelle Spectrograph attached to the 2.16 m telescope at the Beijing Astronomical Observatory (Xinglong, China) for Sirius and Vega, we performed an elemental abundance analysis of 29 ions, in which 23 elements are included, with T(eff) = 9880, log g = 4.40, [Fe/H] = 0.50, and xi (t) = 1.85 km s(-1) for Sirius and T(eff) = 9430, log g = 3.95, [Fe/H] = -0.57, and xi (t) = 1.50 km s(-1) for Vega. The results show different abundance patterns for these two stars. The iron peak elements seem to be enhanced by about 1.0 dex in Sirius relative to Vega. Comparison with previous investigations is present. |
