The selection function of the Gaia DR3 open cluster census

Emily L. Hunt, Tristan Cantat-Gaudin, Friedrich Anders +4

Open clusters are among the most useful and widespread tracers of Galactic structure. The completeness of the Galactic open cluster census, however, remains poorly understood. For…

GaiaUnlimited: The old stellar disc of the Milky Way as traced by the Red Clump

Shourya Khanna, Jie Yu, Ronald Drimmel +9

We present an exploration of the Milky Way's structural parameters using an all-sky sample of RC giants to map the stellar density from the Galactic disc beyond 3 kpc. These evolve…

The completeness of the open cluster census towards the Galactic anticentre

Emily L. Hunt, Tristan Cantat-Gaudin, Friedrich Anders +9

Open clusters have long been used as tracers of Galactic structure. However, without a selection function to describe the completeness of the cluster census, it is difficult to qua…

The realm of Aurora. Density distribution of metal-poor giants in the heart of the Galaxy

Evgeny P. Kurbatov, Vasily Belokurov, Sergey Koposov +11

The innermost portions of the Milky Way's stellar halo have avoided scrutiny until recently. The lack of wide-area survey data, made it difficult to reconstruct an uninterrupted vi…

OCCASO V. Chemical-abundance trends with Galactocentric distance and age

J. Carbajo-Hijarrubia, L. Casamiquela, R. Carrera +12

Context. Open clusters provide valuable information on stellar nucleosynthesis and the chemical evolution of the Galactic disc, as their age and distances can be measured more prec…

How Gaia sheds light on the Milky Way star cluster population

T. Cantat-Gaudin, L. Casamiquela

Star clusters are among the first celestial objects catalogued by early astronomers. As simple and coeval populations, their study has been instrumental in charting the properties…
