[41.02] Multiple Stellar Populations of Some Massive Galactic Globular Clusters as Tracers of Merger Events

S.-J. Yoon, C.-H. Lee, Y.-W. Lee (Ctr. for Space Astrophysics, Yonsei U.)

Our recent study on the Centauri (Lee et al. 1999, Nature, 402, 55) has motivated us to investigate other massive Galactic globular clusters (GC's) with peculiar color-magnitude diagrams (CMD's) morphology to see whether they also have any evidence for multiple stellar populations. Using population models constructed for some of those GC's with composite CMD's (NGC 1851, NGC 2808, NGC 6388, and NGC 6441), we find that their peculiar CMD's can be reproduced in terms of multiple components of population of stars. The implication of our results will be discussed regarding formation of our Galaxy.
