Description
The small and elusive Carina dSph still presents many open questions
concerning its stellar populations and dynamical evolution. It presents
a unique star formation history, with well separated episodes over a
time of ˜10 Gyr. However, the complex star formation history does
not seem to have caused a strong chemical evolution of its stellar
content. Moreover, the occurrence of extra-tidal stars has not been
firmly established. These might be the signature of ongoing tidal
interaction with the Galaxy, or belong to a diffuse halo as suggested by
recent N-body simulations. We undertook a photometric and spectroscopic
investigation over a substantial fraction of the Carina body, to fully
characterize its stellar content.
