  • We first present a self-consistent dynamical model in which ω Cen is formed from an ancient nucleated dwarf galaxy merging with the first generation of the Galactic thin disc in a retrograde manner with respect to the Galactic rotation. Our numerical simulations demonstrate that during merging between the Galaxy and the ω Cen host dwarf with M B ≃ - 14 mag and its nucleus mass of 10 7 M O ., the outer stellar envelope of the dwarf is nearly completely stripped, whereas the central nucleus can… CONTINUE READING
