摘要：
By means of N-body/hydrodynamical simulations we model the evolution of a primordial 10(8) M-circle dot density peak which ends up in an object closely resembling the present day globular duster omega Centauri. We succeed to reproduce the main features of the cluster, namely the structure, kinematics and metallicity distribution. We suggest that omega Centauri might be a cosmological dwarf elliptical, formed at high redshift, evolved in isolation and self-enriched, and eventually fallen inside the potential well of the Milky Way, in agreement with the Searle-Zinn (1978) paradigm for galactic globular cluster formation.
