Milky Way open clusters are very diverse in terms of age, chemical composition, and kinematic properties. Intermediate-age and old open clusters are less common, and it is even harder to find them inside the solar Galactocentric radius, due to the high mortality rate and strong extinction inside...

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
