No Convincing Evidence for Tidal Binary Clusters in the Galaxy
Juan Casado, Zahra Al
Context. The existence of tidal binary clusters (TBCs) in the Milky Way has been repeatedly suggested using Gaia DR3 astrometry and recent catalogs of binary clusters and groups. H…
Open Superclusters II. Discovery of an Inactive Supercluster Including a New Star Cluster in the Solar Neighborhood
Juan Casado, Yasser Hendy, Nikola Faltova +1
The number of known star clusters, associations, and moving groups in the vicinity of the Sun has increased significantly due to the use of Gaia data. We investigated the existence…
Open superclusters I: The most populated primordial groups of open clusters in the third quadrant of the Galactic disc
Juan Casado, Yasser Hendy
An open supercluster (OSC) is defined as a cluster of at least six open clusters (OCs) born from the same giant molecular cloud (GMC). We survey the recent catalogs of OCs based on…
Discovery and description of two young open clusters in the primordial group of NGC 6871
Juan Casado, Yasser Hendy
A primordial group of open clusters containing NGC 6871 is confirmed and described through Gaia DR3 data and the previous literature. It is a star-forming complex containing at lea…
The Effect of Age on the Grouping of Open Clusters: II. Are there old binary clusters?
Juan Casado
In the present study, we continue testing the Primordial Group hypothesis (Casado 2022), which postulates that only sufficiently young open clusters can be binary or multiple, and…
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…
The Effect of Age on the Grouping of Open Clusters: The Primordial Group Hypothesis
Juan Casado
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 OC…
The list of possible double and multiple open clusters between galactic longitudes 240 and 270 degrees
Juan Casado
This work studies the candidate double and multiple open clusters (OCs) in the galactic sector from l = 240o to l = 270o, which contains the Vela-Puppis star formation region. To d…
New Open Clusters Found by Manual Mining of Data in Gaia DR2
Juan Casado
The physical nature of a series of 20 new open clusters is confirmed employing existing data on putative star members, mainly from second Gaia Data Release (DR2). The clusters were…
