Scientific paper

We propose to obtain central region K-band spectra for a sample of N ~ 30 field elliptical galaxies. An analysis of the central near-IR colors of these galaxies suggests that some of these galaxies may contain first-ascent giant branches (FGB) similar to the unusual FGB seen in the metal-rich Galactic globular clusters Liller 1 and NGC 6440. We wish to test this hypothesis by measuring the equivalent widths of the Na I 2.207(micron) and Ca I 2.263(micron) as well as the CO 2.36(micron) index. These new EW and CO index measurements will be compared to previously published data for K and M giants in the Local Solar Neighborhood, Baade's Window, and the Liller 1 and NGC 6440 clusters.
