The tricky galactic cluster NGC2420
P. G. Prada Moroni, V. Castellani, S. Degl'Innocenti +1
We discuss the CM diagram of the galactic cluster NGC2420 to the light of current theoretical predictions. By relying on the most recent updating of the physical input, one finds t…

The stellar content of the Galaxy: the white dwarf population
M. Cignoni, V. Castellani, S. Degl'Innocenti +2
On the basis of theoretical evolutionary expectations, we develop a Galactic model reproducing star counts and synthetic color-magnitude diagrams of field stars, which include the…

RR Lyrae variables in Omega Centauri: a theoretical route
V. Castellani, S. Degl'Innocenti, M. Marconi
We present a theoretical approach to infer information about RR Lyrae variables from the morphology of their light curves. The method, already successfully applied to the field fir…
