Resumen:
We present the results on the age estimates of 36 Large Magellanic Cloud (LMC) clustersobtained for the first time from CCD Washington CT 1 T 2 photometry. By using the (T 1 , C −T 1 ) and (T 1 , T 1 − T 2 ) diagrams, we estimated ages for the cluster sample using the δT 1 index.We confirm that the studied cluster sample belong to the ∼2 Gyr bursting formation epoch ofthe LMC. Furthermore, when rebuiling the cluster age distribution – taken into account theestimated age errors – we found that the number of clusters with ages between 1 and 3 Gyr nowdoubles that of the known bursting cluster population, which suggests that the tidal interactionbetween both Magellanic Clouds and, perhaps, also the Milky Way, was more stronger thanexpected.
