Aims: The nature of the thick disc and its relation to the thin disc is presently an important subject of debate. In fact, the structural and chemo-dynamical...

PublicationThe Gaia-ESO Survey: the most metal-poor stars in the Galactic bulge
We present the first results of the EMBLA survey (Extremely Metal-poor BuLge stars with AAOmega), aimed at finding metal-poor stars in the Milky Way bulge...

PublicationThe Gaia-ESO Survey: the origin and evolution of s-process elements
Context. Several works have found an increase of the abundances of the s-process neutron-capture elements in the youngest Galactic stellar populations. These...

PublicationThe galactic globular cluster NGC 1851: its dynamical and evolutionary properties
We have completely mapped the Galactic globular cluster NGC 1851 with large-field, ground-based VI CCD photometry and pre-repair HST/WFPC1 data for the central...

PublicationThe galactic globular cluster system - Constraints from Synthetic Horizontal Branches
Synthetic horizontal branches, constructed on the basis of Sweigart and Gross (1976) horizontal branch star models and of the recently revised theoretical...

PublicationThe Galactic globular cluster system - Theoretical constraints for alpha-enhanced compositions
This paper discusses synthetic horizontal branches constructed from a grid of horizontal-branch (HB) evolutionary tracks with the alpha-elements enhanced by a...

PublicationThe Galactic initial mass function: origin in the combined mass distribution functions of dust grains and gas clouds
We present here a theoretical model to account for the stellar initial mass function (IMF) as a result of the composite behaviour of the gas and dust...
