Scientific paper

I derived the elemental abundances of metallic-line star 2 UMa, using high-dispersion, high signal-to-noise ratio spectra obtained from Dominion Astrophysical Observatory. This study used Kurucz's ATLAS9 and WIDTH9 programs. The star was selected as 1) it has not been the subject of a detailed elemental abundances analysis, and 2) it is relatively sharp-lined and hot enough so that the continuum can be well placed even in the blue. For even cooler Am stars determining the continium will be a major problem. As a guide for the broad-lined and cooler Am stars, a spectral line atlas of 2 UMa will be prepared.
