General Description

We propose to acquire FLAMES/UVES spectra of evolved stars in four open
 clusters located at Galactocentric
distances lower than 7 kpc. The data will allow us to derive the cluster chemical
 composition and thus to trace the radial
metallicity gradient; in the inner parts of the disk, a region which is so far very
 poorly explored. by comparison
with available data for Cepheids we will also be able to constrain the time evolution
 of the gradient. This is
crucial to understand the role of the dynamical collapse of the halo in the inner
 regions respect to the accretion
due the infall from the intergalactic medium and from mergers.
Giraffe fibers are used to observe unevolved cluster candidates with the aim to
 measure their radial velocities and to confirm their membership.
