The unprecedented quality of the astrometric measurements obtained with the ESA Gaia
spacecraft have initiated a revolution in Milky Way astronomy. Studies of star clusters in …

OB associations are unbound groups of young stars made prominent by their bright OB
members, and have long been thought to be the expanded remnants of dense star clusters …

Context. Many of the open clusters listed in modern catalogues were initially reported by
visual astronomers as apparent overdensities of bright stars. As observational techniques …

Context. Open clusters are key targets for studies of Galaxy structure and evolution, and
stellar physics. Since the Gaia data release 2 (DR2), the discovery of undetected clusters …

Context. Open clusters (OCs) trace the evolution of the Galactic disc with great accuracy.
Gaia and large ground-based spectroscopic surveys make it possible to determine their …

Young stellar associations hold a star formation record that can persist for millions of years,
revealing the progression of star formation long after the dispersal of the natal cloud. To …

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 …

We systematically searched for open clusters in the solar neighborhood within 500 pc using
the pyUPMASK and HDBSCAN clustering algorithms based on Gaia DR3. Taking into …

We identify members of 65 open clusters in the solar neighborhood using the machine-
learning algorithm StarGO based on Gaia EDR3 data. After adding members of 20 clusters …
