The Dark and Luminous Matter coupling in the formation of spheroids: a SPH investigation
Cesario Lia, Giovanni Carraro, Paolo Salucci
Using N-body/hydrodynamical simulations which include prescriptions for Star Formation, Feed-Back and Chemical Evolution, we explore the interaction between baryons and Dark Matter…
NGC 6994: an open cluster which is not an open cluster
Giovanni Carraro
We report on CCD photometry in the Johnson B,V and I passbands for 146 stars in a 9' \times 9' region around the southern aggregate NGC 6994 (C 2056-128), which appears in the Lyng…
On the formation and evolution of the globular cluster Omega Centauri
Giovanni Carraro, Cesario Lia
By means of N-body/hydrodynamical simulations we model the evolution of a primordial 10^{8} solar masses density peak which ends up in an object closely resembling the present day…
On the peculiar red clump morphology in the open clusters NGC 752 and NGC 7789
L. Girardi, J. -C. Mermilliod, G. Carraro
The red clump stars in the open cluster NGC 752 present a peculiar distribution in the colour-magnitude diagran (CMD): the clump is observed to present a faint extension, slightly…
