Context. As observational evidence steadily accumulates, the nature of the Galactic bulge has proven to be rather complex: the structural, kinematic, and chemical analyses often lead to contradictory conclusions. The nature of the metal-rich bulge - and especially of the metal-poor bulge - and... Read more
A&A highlight, Vol. 601, in section 5. Galactic structure, stellar clusters and populations Context. The radial metallicity distribution in the Galactic thin disc represents a crucial constraint for modelling disc formation and evolution... Read more
Context. Trumpler 23 is a moderately populated, intermediate-age open cluster within the solar circle at a RGC ~ 6 kpc. It is in a crowded field very close to the Galactic plane and the color–magnitude diagram shows significant field contamination and possible differential reddening; it... Read more
The Gaia-ESO survey (GES) is now in its fifth and last year of observations and has produced tens of thousands of high-quality spectra of stars in all Milky Way components. Read more
We show that non-magnetic models for the evolution of pre-main-sequence (PMS) stars cannot simultaneously describe the colour–magnitude diagram (CMD) and the pattern of lithium depletion seen in the cluster of young, low-mass stars surrounding γ2 Velorum. The age of 7.5 ± 1 Myr inferred... Read more
