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 …

Context. Open clusters are convenient probes of the structure and history of the Galactic
disk. They are also fundamental to stellar evolution studies. The second Gaia data release …

Context. The Gaia-ESO Public Spectroscopic Survey is an ambitious project designed to
obtain astrophysical parameters and elemental abundances for 100 000 stars, including …

We present a novel view on the morphology and dynamical state of ten prominent, nearby
(≤ 500 pc), and young (∼ 30–300 Myr) open star clusters with Gaia DR2: α Per, Blanco 1 …

Context. The large astrometric and photometric survey performed by the Gaia mission allows
for a panoptic view of the Galactic disc and its stellar cluster population. Hundreds of stellar …

Aims. The purpose of this work is to evaluate how several elements produced by different
nucleosynthesis processes behave with stellar age and provide empirical relations to derive …

We report the discovery of TOI 837b and its validation as a transiting planet. We characterize
the system using data from the NASA Transiting Exoplanet Survey Satellite mission, the ESA …

Context. In the era of large spectroscopic surveys, massive databases of high-quality spectra
coupled with the products of the Gaia satellite provide tools to outline a new picture of our …

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 …

ABSTRACT A growing disquiet has emerged in recent years that standard stellar models are
at odds with observations of the colour–magnitude diagrams (CMDs) and lithium depletion …
