NGC 1605 is not a binary cluster
Friedrich Anders, Alfred Castro-Ginard, Juan Casado +2
The open star cluster NGC 1605 has recently been reported to in fact consist of two clusters (one intermediate-aged and one old) that merged via a flyby capture. Here we show that…
Hunting for open clusters in Gaia EDR3: new open clusters found with OCfinder
A. Castro-Ginard, C. Jordi, X. Luri +6
The improvements in the precision of the published data in \textit{Gaia} EDR3 with respect to \textit{Gaia} DR2, particularly for parallaxes and proper motions, offer the opportuni…
OCCASO IV. Radial Velocities and Open Cluster Kinematics
R. Carrera, L. Casamiquela, J. Carbajo-Hijarrubia +8
Context: Open clusters (OCs) are widely used as test particles to investigate a variety of astrophysical phenomena, from stellar evolution to Galactic evolution. Gaia and the compl…
Abundance-age relations with red clump stars in open clusters
L. Casamiquela, C. Soubiran, P. Jofré +8
Context: Precise chemical abundances coupled with reliable ages are key ingredients to understand the chemical history of our Galaxy. Open Clusters (OCs) are useful for this purpos…
Gaia Early Data Release 3: Structure and properties of the Magellanic Clouds
Gaia Collaboration, X. Luri, L. Chemin +417
We compare the Gaia DR2 and Gaia EDR3 performances in the study of the Magellanic Clouds and show the clear improvements in precision and accuracy in the new release. We also show…
The star cluster age function in the Galactic disc with Gaia DR2: Fewer old clusters and a low cluster formation efficiency
Friedrich Anders, Tristan Cantat-Gaudin, Irene Quadrino-Lodoso +4
We perform a systematic reanalysis of the age distribution of Galactic open star clusters. Using a catalogue of homogeneously determined ages for 834 open clusters contained in a 2…
Hunting for open clusters in \textit{Gaia} DR2: the Galactic anticentre
A. Castro-Ginard, C. Jordi, X. Luri +2
The Gaia Data Release 2 (DR2) provided an unprecedented volume of precise astrometric and excellent photometric data. In terms of data mining the Gaia catalogue, machine learning m…
Age determination for 269 DR2 Open Clusters
D. Bossini, A. Vallenari, A. Bragaglia +9
. Gaia Second Data Release provides precise astrometry and photometry for more than 1.3 billion sources. This catalog opens a new era concerning the characterization of op…
Expanding associations in the Vela-Puppis region: 3D structure and kinematics of the young population
T. Cantat-Gaudin, C. Jordi, N. J. Wright +9
The Vela-Puppis region is known to host the Vela OB2 association as well as several young clusters featuring OB and pre-main sequence stars. Several spatial and kinematic subgroups…
A ring in a shell: the large-scale 6D structure of the Vela OB2 complex
T. Cantat-Gaudin, M. Mapelli, L. Balaguer-Núñez +3
The Vela OB2 association is a group of 10 Myr stars exhibiting a complex spatial and kinematic substructure. The all-sky Gaia DR2 catalogue contains proper motions, parallaxes (a p…
A Gaia DR2 view of the Open Cluster population in the Milky Way
T. Cantat-Gaudin, C. Jordi, A. Vallenari +10
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 contains…
Gaia Data Release 2: Photometric content and validation
D. W. Evans, M. Riello, F. De Angeli +9
Aims. We describe the photometric content of the second data release of the Gaia project (Gaia DR2) and its validation along with the quality of the data. Methods. The validation w…
Characterising Open Clusters in the solar neighbourhood with the Tycho-Gaia Astrometric Solution
T. Cantat-Gaudin, A. Vallenari, R. Sordo +8
The Tycho-Gaia Astrometric Solution (TGAS) subset of the first Gaia catalogue contains an unprecedented sample of proper motions and parallaxes for two million stars brighter than…
NGC 6705 a young -enhanced Open Cluster from OCCASO data
L. Casamiquela, R. Carrera, L. Balaguer-Núñez +12
The stellar [/Fe] abundance is sometimes used as a proxy for stellar age, following standard chemical evolution models for the Galaxy, as seen by different observational results…
OCCASO II. Physical parameters and Fe abundances of Red Clump stars in 18 Open Clusters
L. Casamiquela, R. Carrera, S. Blanco-Cuaresma +13
Open Clusters have long been used to study the chemo-dynamical evolution of the Galactic disk. This requires an homogeneously analysed sample covering a wide range of ages and dist…
