Resumen:
Our group has been studying for several years star clusters and field stars of the Small Magellanic Cloud (SMC), using the FORS2 instrument on the VLT (Paranal, Chile). We have derived metallicities from CaT lines and ages from both the δV parameter and (V,V-I) color-magnitude diagrams. We have studied 29 star clusters and approximately 700 field stars surrounding these clusters. We have analyzed and compared the chemical properties of those clusters and their surrounding field stars. We found evidence for possible differences between the chemical evolution histories of these two different SMC stellar populations.
