New candidate intermediate-age star clusters in the Small Magellanic Cloud

We present the results on the age and metallicity estimates of nine Small Magellanic Cloud (SMC) clusters (AM3, HW31, 40, 41, 42, 59, 63, L91 and NGC339) obtained from CCD WashingtonCT1T2 photometry. We confirm AM3 and NGC339 as intermediate-age and metal-poor clusters, and report for the first time...
