Abstract
Conclusions. In all probability, the fractional critical angular rotation rate, Omega/Omega(c), is one of the main parameters governing the occurrence of the Be phenomenon. If the Be character is only acquired during the course of evolution, the key circumstance is the evolution of Omega/Omega(c), which is not only dependent on metallicity but differently so for different mass ranges. As a result, even if the Be phenomenon is driven basically by a single parameter (namely Omega/Omega(c)), it can assume a complex multi-parametric appearance. The large cluster-to-cluster differences, which seem stronger than all other variations, serve as a caveat that this big picture may undergo significant second-order modulations (e. g., pulsations, initial angular momentum, etc.).

| The authors acknowledge the referee for valuable comments that helped to present the essence of the paper more clearly. C. M. thanks Drs. A.-M. Hubert, M. Floquet, and Y. Fremat for sharing useful information during the preliminary analysis of our data. Dr. E. Bertin's adaptation of his SExtractor package proved most helpful for the mass reduction of the observations. This research has made use of the Simbad and Vizier databases maintained at CDS, Strasbourg, France, of NASA's Astrophysics Data System Bibliographic Services, and of the NASA/IPAC Infrared Science Archive, which is operated by the Jet Propulsion Laboratory, California Institute of Technology, under contract with the U.S. National Aeronautics and Space Administration. This publication makes use of data products from the Two Micron All Sky Survey, which is a joint project of the University of Massachusetts and the Infrared Processing and Analysis Center/California Institute of Technology, funded by the U.S. National Aeronautics and Space Administration and the U.S. National Science Foundation. C. M. is grateful for support from ESO's DGDF in 2006. |
