| Sumario: | As part of our uninterrupted systematic study of star clusters in the Large Magellanic Cloud (LMC), we present preliminary results for 4 faint, unstudied LMC star clusters. Based on CCD images in the Washington system obtained with the 4 m telescope at Cerro Tololo Inter-American Observatory (Chile), we derive approximate ages and metallicities using theoretical isochrones in the (T,C-T1) diagrams. The clusters are aged between 550 and 1300 Myr, being all of them relatively metal-poor. Their approximate radii were estimated from stellar density profiles. The current study will be soon extended into a vast LMC region wherein numerous unstudied star clusters can be found (Palma 2011). |
