New atlas of open star clusters
Open Astronomy, 2017 Due to numerous new discoveries of open star clusters in the last two decades, astronomers need an easy-touse resource to get visual information on the relative position of clusters in the sky. Therefore we propose a new atlas of open star clusters.

Open Star Clusters and Their Asymmetrical Tidal Tails
The Astrophysical JournalStars that evaporate from their star cluster by the energy equipartition process end up in either a leading or a trailing tidal tail. In Newtonian gravitation and for open star clusters in the solar vicinity, the tidal threshold, or práh, for escape is ...

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 ...

Be STARS IN THE OPEN CLUSTER NGC 6830 [PDF]
The Astronomical Journal, 2016 ABSTRACT We report the discovery of two new Be stars, and re-identify one known Be star in the open cluster NGC 6830. Eleven Hα emitters were discovered using the Hα imaging photometry of the Palomar Transient Factory Survey. Stellar membership of the candidates was verified with photometric and kinematic information using 2MASS data and
