EXTENDED SURVEYS OF MC STAR-CLUSTERS

The location of the LMC clusters, their age distribution and dynamical parameters have shown that two star cluster systems exist in this galaxy: 1) one extended system, elliptical in shape, which contains all intermediate and old star clusters and 2) another system, again elliptical, but smaller in diameter, superimposed on the other and inclined by about 50 degrees from the latter. It contains the most massive, very young globular clusters which are still at their early phases of dynamical evolution. The existence of very rich stellar associations, binary star clusters and very elliptical ones located in this system, indicates that massive star clusters have formed very recently and are still under formation.
