An Abundance Analysis of the Photometric Standard 29 PISCIUM
Abstract
A fine analysis of the photometric standard star 29 Psc has been performed by using flux-constant hydrogen-line-blanketed model atmospheres. The observable quantities-Balmer and Paschen slopes, Balmer discontinuity, and H and He I lines-were used to determine the final model parameters: = 15,1500 K, log g = 4.08 and N(He)/ N(H) = 0.027. Lines from 14 elements besides H and He were identified; five elements (C, Mg, Si, Ti, and Fe) had a sufficient number of unblended lines with known gf-values to attempt an abundance determination.
