Abstract:
We present a high resolution (R=90000) spectral atlas of the F5Ib
star Alpha Per covering the 3810-8100Å region. The atlas,
based on data obtained with the aid of the echelle spectrograph BOES
fed by 1.8-m telescope at Bohyunsan observatory (Korea) is a result of
co-addition of a few well-exposed spectra. A final signal-to-noise
ratio is ∼800 at ∼6000Å. The atlas is compared with the
synthetic spectrum computed using the code based on (Kurucz, 1995,
ASP Conf. Ser. 81, 583) software and databases.
The adopted model atmosphere parameters are Teff=6240±20K,
logg=0.58±0.04, and Vturb=3.20±0.05km/s. We also derived the iron
abundance of [Fe/H]=-0.28±0.06. The spectral lines of
Alpha Per have been identified by matching the synthetic spectrum with
the observed one. The atlas is presented in figures and available
in digital form at http://www.boao.re.kr/BOES/atlas/hd20902.html along
with synthetic spectrum and spectral line identification tables.
