SUMMARY:The Incredible Omega Centauri- A Laboratory for Chemical Enric
 hment\, Astronomy Colloquium\, Caty Pilachowski\, Univ of Indiana-Bloo
 mington
DESCRIPTION:The globular cluster Omega Centauri continues to surprise 
 us - a dispersion in metallicity\, multiple main sequences\, and even 
 a black hole.  As a laboratory for chemical enrichment\, Omega Centaur
 i is unparalled.  Detailed studies of the composition of a large sampl
 e of giant stars in the cluster reveal the complex nature of chemical 
 enrichment that occurred.  Clues to the history of the cluster can be 
 found in the changing abundances of light and heavy elements with meta
 llicity.  Comparison to other bulge\, disk\, and dwarf spheroidal stel
 lar populations showing evidence of chemical enrichment suggests that 
 Omega Centauri's path has been unique.
