Nuevos candidatos a cúmulos viejos en la Nube Menor de Magallanes
We present the results on the age and metallicity estimates of nine SMC clusters (AM 3, HW 31, 40, 41, 42, 59, 63, L 91 and NGC 339) obtained from CCD Washington CT1T2 photometry. We confirm AM 3 and NGC 339 as intermediate-age and metal-poor clusters, and report for the first time that the remainin...

| Summary: | We present the results on the age and metallicity estimates of nine SMC clusters (AM 3, HW 31, 40, 41, 42, 59, 63, L 91 and NGC 339) obtained from CCD Washington CT1T2 photometry. We confirm AM 3 and NGC 339 as intermediate-age and metal-poor clusters, and report for the first time that the remaining seven clusters are also intermediate-age or old clusters (t ∼ 4.3 - 9.3 Gyr), which represents an increase of ≥ 60% of the total known intermediate-age/old cluster population in the SMC. The studied clusters have metal contents ranging from intermediate metalpoor ([Fe/H] ≈ -0.7 dex) down to metal-poor ([Fe/H] ≈ -1.3 dex) values. A detailed version of this work can be seen in Piatti (2011, MNRAS, 416, L89). |
