Star clusters stand at the intersection of much of modern astrophysics: the ISM, gravitational
dynamics, stellar evolution, and cosmology. Here, we review observations and theoretical …

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. Gaia Data Release 3 (Gaia DR3) contains the second release of the combined
radial velocities. It is based on the spectra collected during the first 34 months of the nominal …

We construct from Gaia eDR3 an extensive catalogue of spatially resolved binary stars
within≈ 1 kpc of the Sun, with projected separations ranging from a few au to 1 pc. We …

The spectral analysis and data products in Data Release 16 (DR16; 2019 December) from
the high-resolution near-infrared Apache Point Observatory Galactic Evolution Experiment …

Context. The third Gaia data release (DR3) provides a wealth of new data products. The
early part of the release, Gaia EDR3, already provided the astrometric and photometric data …

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

A gravitational anomaly is found at weak gravitational acceleration g N≲ 10− 9 ms− 2 from
analyses of the dynamics of wide binary stars selected from the Gaia DR3 database that …

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 …
