Abundance analysis of the chemically peculiar star HD 74169 (A0IVp) .

We present the results of the abundance analysis of the chemically peculiar star HD 74169 based on the echelle spectrum obtained with the spectrograph UVES. This high resolution and high signal-to-noise observations are compared with a synthetic spectrum computed with the SYNTHE code. As an input atmosphere model for SYNTHE we used an ATLAS 9 model with effective temperature Teff = 10000 K and surface gravity log g = 4.0 dex. The iterative procedure used to derive stellar individual abundances allows us to take into account even blended lines. The best fit to the observed spectral line profiles was obtained with a rotational velocity Ve sin i = 20 km s−1and turbulence Vturb = 2.1 km s−1. The average abundances of HD 74169 are typical for an Ap star of Cr type: C is deficient, Cr and Fe are strongly overabundant. The analyzed heavy and rare-earth elements are also overabundant.
