Tidal tails of open star clusters as probes of early gas expulsion [PDF]
Astronomy & Astrophysics, 2020 Context. Star clusters form in the densest parts of infrared dark clouds. The emergence of massive stars expels the residual gas that has not formed stars yet.

Global survey of star clusters in the Milky Way. VII. Tidal parameters and mass function [PDF]
Astronomy & Astrophysics, 2023 We built Galactic open star cluster mass functions (CMFs) for different age sub-samples in the wider solar neighbourhood. We present a simple cluster formation and evolution model to reproduce the main features of the CMFs.

Hunting for Neighboring Open Clusters with Gaia DR3: 101 New Open Clusters within 500 pc
The Astrophysical Journal Supplement Series, 2023 We systematically searched for open clusters in the solar neighborhood within 500 pc using the pyUPMASK and HDBSCAN clustering algorithms based on Gaia DR3.

3D Morphology of Open Clusters in the Solar Neighborhood with Gaia EDR 3. II. Hierarchical Star Formation Revealed by Spatial and Kinematic Substructures [PDF]
Astrophysical Journal, 2022 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 from previous studies we obtain 85 clusters, and study their morphology and ...

Unveiling Hidden Stellar Aggregates in the Milky Way: 1656 New Star Clusters Found in Gaia EDR3
The Astrophysical Journal Supplement Series, 2022 We report 1656 new star clusters found in the Galactic disk (∣ b ∣ < 20°) beyond 1.2 kpc, using Gaia EDR3 data. Based on an unsupervised machine-learning algorithm, DBSCAN, and following our previous studies, we utilized a unique method to do the data ...

The Astrophysical Journal Supplement Series, 2023 Studying open clusters (OCs) may help to provide a comprehensive understanding of the structure and evolution of the Milky Way. Many previous studies have systematically searched for OCs near the solar system within 1.2 kpc or 20° of Galactic latitude ...

Pulsatin stars in open clusters [PDF]
Communications in Asteroseismology, 2007 We report studies that are carried out with the aim of searching for and studying short-period variable stars in northern open clusters. The background for these studies is described along with the results that have been obtained up to now.

THE SPATIAL DISTRIBUTION OF STARS IN OPEN CLUSTERS [PDF]
The Astrophysical Journal, 2009 AbstractWe study the internal spatial structure of 16 open clusters in the Milky Way spanning a wide range of ages. For this, we use the minimum-spanning-tree method (the Q parameter, which enables one to classify the stellar distribution as either radially or fractally clustered), King-profile fitting, and the correlation dimension (Dc) for those ...

Kinematic Properties of Open Star Clusters with Data from the Gaia DR2 Catalogue [PDF]
Astronomy letters, 2019 We consider open star clusters (OSCs) with the proper motions, parallaxes, and line-of-sight velocities calculated by various authors from Gaia DR2 data.
