Context. In the last 15 years different ground-based spectroscopic surveys have been
started (and completed) with the general aim of delivering stellar parameters and elemental …

Current theories of planetary evolution predict that infant giant planets have large radii and
very low densities before they slowly contract to reach their final size after about several …

In this paper, we make use of data collected for open cluster members by high-resolution
spectroscopic surveys and programmes (ie, APOGEE, Gaia-ESO, GALAH, OCCASO, and …

Spectroscopy from the final internal data release of the Gaia–ESO Survey (GES) has been
combined with Gaia EDR3 to assign membership probabilities to targets observed towards …

We present an empirical model of age-dependent photospheric lithium depletion, calibrated
using a large homogeneously analysed sample of 6200 stars in 52 open clusters, with ages …

I have used high-precision photometry and astrometry from the early installment of the third
data release of Gaia (EDR3) to perform a survey for members of the stellar populations …

Tidal streams of disrupted clusters are powerful probes of the gravitational potential of the
Galaxy and they are routinely detected in the stellar halo of the Milky Way. It was recently …

We report the discovery and characterization of a nearby (∼ 85 pc), older (27±3 Myr),
distributed stellar population near Lower Centaurus Crux (LCC), initially identified by …

Context. Open clusters provide unambiguous clues to understand the evolution of 7 Li at the
surface of low-mass stars and its possible correlation with stellar rotation, which is a …

Magnetic activity and rotation are related to the age of low-mass main-sequence stars. To
further constrain these relations, we study a sample of 574 main-sequence stars members of …
