Abstract
ABSTRACTWe present a high‐resolution (λ/δλ = 90,000) spectral atlas of the F5 Ib star α Per covering the 3810–8100 Å region. The atlas, based on data obtained with the aid of the echelle spectrograph BOES fed by the 1.8 m telescope at Bohyunsan Observatory (Korea), is the result of the co‐addition of a few well‐exposed spectra. The final signal‐to‐noise ratio is ∼800 at ∼6000 Å. The atlas is compared with a synthetic spectrum computed using a code based on Kurucz software and databases. The adopted model atmosphere parameters are Teff = 6240 ± 20 K, log g = 0.58 ± 0.04, and vmicro = 3.20 ± 0.05 km s−1. We also derived an iron abundance of [Fe/H] = -0.28 ± 0.06. The spectral lines of α Per have been identified by matching the synthetic spectrum with the observed one. The atlas is presented in figures and available in digital form on the World Wide Web, along with the synthetic spectrum and spectral line identification tables.
