New insights on the bursting formation of star clusters in the Large Magellanic Cloud

We present the results on the age estimates of 36 Large Magellanic Cloud (LMC) clusters obtained for the first time from CCD Washington CT1T2 photometry. By using the (T1, C-T1) and (T1, T1-T2) diagrams, we estimated ages for the cluster sample using the δT1 index. We confirm that the studied cluste...
