Abstract:For the first time, we provide metallicities for 15 star clusters of the Small Magellanic Cloud (SMC) determined from the CaII triplet lines in spectra obtained with the FORS2 instrument at the Very Large Telescope (Chile). Together with this information, we add the ages and accurate metall...

Sumario:Abstract:For the first time, we provide metallicities for 15 star clusters of the Small Magellanic Cloud (SMC) determined from the CaII triplet lines in spectra obtained with the FORS2 instrument at the Very Large Telescope (Chile). Together with this information, we add the ages and accurate metallicities previously determined in a scale similar to ours for another 22 clusters. Using this enlarged sample, the SMC chemical properties, particularly the age-metallicity relationship, are examined.
