Elemental Abundance Analyses with DAO Spectrograms XXXVII. The Normal A0 IV Star γ Geminorum

We performed a fine analysis of the normal sharp-lined A0 IV star \u3b3 Geminorum with spectra having signal-to-noise ratios at the continuum of 500\u20131200 that were consistent with previous studies of this series. Our spectra have wavelength ranges of \u3bb\u3bb3829\u20134730, 4873\u20134931, 4983\u20135042, and 5070\u20135210. The spectra measured with the program REDUCE have a two-pixel resolution of 0.072 \uc5. We used ATLAS9 models and the program WIDTH9 to derive the abundances of the metals. Most derived abundances are close to solar with the abundances of the heaviest elements Zr, Ba, La, Ce, and Nd showing greater than solar values. This suggests by comparison with the abundances of other normal and Am stars that \u3b3 Gem might exhibit an incipient Am star phenomenon.Peer reviewed: YesNRC publication: Ye
