After hydrogen and helium, oxygen, carbon, and nitrogen—hereinafter, the CNO elements—
are the most abundant species in the universe. They are observed in all kinds of …

Context. We present the third data release of the European Space Agency's Gaia mission,
Gaia DR3. This release includes a large variety of new data products, notably a much …

Context. The Gaia DR3 catalogue contains, for the first time, about 800 000 solutions with
either orbital elements or trend parameters for astrometric, spectroscopic, and eclipsing …

Context. The chemo-physical parametrisation of stellar spectra is essential for
understanding the nature and evolution of stars and of Galactic stellar populations. A …

Context. The motion of stars has been used to reveal details of the complex history of the
Milky Way, in constant interaction with its environment. Nevertheless, to reconstruct the …

Context. The spatial distribution of elemental abundances and their time evolution are
among the major constraints to disentangling the scenarios of formation and evolution of the …

ABSTRACT WEAVE, the new wide-field, massively multiplexed spectroscopic survey facility
for the William Herschel Telescope, saw first light in late 2022. WEAVE comprises a new 2 …

Yttrium (Y), a key s-process element, is commonly used in nucleosynthesis studies and as a
Galactic chemical clock when combined with magnesium (Mg). We study the applicability of …

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 …

The very massive first stars (m> 100) were fundamental to the early phases of reionization,
metal enrichment, and supermassive black hole formation. Among them, those with are …
