Properties of a Proper-Motion Selected Sample of Giants in the Small Magellanic Cloud near NGC 121
Nicholas B. Suntzeff, Alistair R. Walker, Verne V. Smith +3
We present both low and high-dispersion abundance analyses of giants drawn from the zero proper motion sample near NGC 121. For the sample of 35 stars, the mean metallicity of the…
