Mass segregation effects in very young open clusters
Abstract
We derived proper motions and membership probabilities of stars in the regions of two very young (~ 2-4 Myr-old) open clusters NGC 2244 and NGC 6530. Both clusters show clear evidence of mass segregation, which provides strong support for the suggestion that the observed mass segregation is - at least partially - due to the way in which star formation has proceeded in these complex star-forming regions ("primordial" mass segregation).
