The Primordial group hypothesis states that only young enough open clusters (OCs) can be multiple, and old OCs are essentially single since the gravitational interaction between OCs in primordial groups is very weak, and the probability of gravitational capture of two OCs without disruption is very low. We test such postulate through four different studies using a manual search of Gaia EDR3 and extensive literature. First, we revisit the work of de La Fuente Marcos & de La Fuente Marcos (2009…

The list of possible double and multiple open clusters between galactic longitudes 240 and 270 degrees
This work studies the candidate double and multiple open clusters (OCs) in the galactic sector from l = 240 o to l = 270 o , which contains the Vela-Puppis star formation region. To do that, we have
A RAVE investigation on galactic open clusters. II, Open cluster pairs, groups and complexes
CONTEXT: It is generally agreed upon that stars form in open clusters (OCs) and stellar associations, but little is known about structures in the Galactic OC population; whether OCs and stellar
Double or binary: on the multiplicity of open star clusters
Context. Observations indicate that the fraction of potential binary star clusters in the Magellanic Clouds is about 10%. In contrast, it is widely accepted that the binary cluster frequency in the
Untangling the Galaxy. I. Local Structure and Star Formation History of the Milky Way
Gaia DR2 provides unprecedented precision in measurements of the distance and kinematics of stars in the solar neighborhood. Through applying unsupervised machine learning on DR2's 5-dimensional
A Gaia DR2 view of the open cluster population in the Milky Way
Context. 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 precise
Clusters and mirages: cataloguing stellar aggregates in the Milky Way
Many open clusters listed in modern catalogues were initially reported by visual astronomers as apparent overdensities of bright stars. As observational techniques and analysis methods continue to
Properties of star clusters – II. Scaleheight evolution of clusters
Until now, it has been impossible to observationally measure how star cluster scaleheight evolves beyond 1 Gyr as only small samples have been available. Here, we establish a novel method to
New Open Clusters Found by Manual Mining of Data Based in Gaia DR2
The physical nature of a series of 20 new open clusters is confirmed employing existing data on putative star members, mainly from the second Gaia Data Release (DR2). The clusters were discovered as
Evolution of the local spiral structure of the Milky Way revealed by open clusters
The structure and evolution of the spiral arms of our Milky Way are basic but long-standing questions in astronomy. In particular, the lifetime of spiral arms is still a puzzle and has not been well
Open clusters in the Third Galactic Quadrant. III: alleged binary clusters
Aims. We aim to determine accurate distances and ages of eight open clusters in order to: (1) assess their possible binarity (2) provide probes to trace the structure of the Third Galactic Quadrant.
