Variability of Be Stars in Southern Open Clusters [PDF]
The Astrophysical Journal, 2009 We recently discovered a large number of highly active Be stars in the open cluster NGC 3766, making it an excellent location to study the formation mechanism of Be star disks.

A Star Catalog for the Open Cluster NGC 188 [PDF]
Publications of the Astronomical Society of the Pacific, 2004 We present new BVRI broad-band photometry for the old open cluster NGC188 based upon analysis of 299 CCD images either obtained by us, donated by colleagues, or retrieved from public archives. We compare our results on a star-by-star basis with data from eleven previous photometric investigations of the cluster.

Internal kinematics of open star clusters [PDF]
Monthly Notices of the Royal Astronomical Society, 1989 La cinematique interne dans 8 amas ouverts est etudiee sur des donnees des mouvements propres. La dependance de la dispersion intrinseque dans le mouvement propre sur la masse stellaire et la distance radiale du centre de l'amas est examinee. Ces dispersions sont trouvees independantes de la masse stellaire et des distances radiales pour la plupart des

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 ...

Be stars in open clusters [PDF]
Astronomy and Astrophysics Supplement Series, 1997 We present Hα line profiles (, at continuum level, for some objects) for 58 stars in 8 northern open clusters and associations, complemented with Hβ and Hγ profiles for 36 of them as well as Hδ and Hϵ for 16 programme stars. Our observations, though lower in resolution, yield results which are in good agreement with those obtained in earlier works

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.
