The Dynamics of Open Clusters [PDF]
Symposium - International Astronomical Union, 1980 This is a review of a subject that turns out to be rather dismal. Both in theory and in observation we know and understand open clusters poorly – either in comparison with globular clusters or on an absolute basis.

The Distribution of Open Clusters in the Galaxy [PDF]
Frontiers in Astronomy and Space Sciences, 2021 In this work we explore the new catalog of galactic open clusters that became available recently, containing 1,750 clusters that have been re-analyzed using the Gaia DR2 catalog to determine the stellar memberships. We used the young open clusters as tracers of spiral arms and determined the spiral pattern rotation speed of the Galaxy and the ...

Eclipsing Binaries in Open Clusters [PDF]
Astrophysics and Space Science, 2006 AbstractDetached eclipsing binaries are very useful objects for calibrating theoretical stellar models and checking their predictions. Detached eclipsing binaries in open clusters are particularly important because of the additional constraints on their age and chemical composition from their membership of the cluster.

Open clusters: their kinematics and metallicities [PDF]
Proceedings of the International Astronomical Union, 2007 AbstractWe review our work on Galactic open clusters in recent years, and introduce our proposed large program for the LOCS (LAMOST Open Cluster Survey). First, based on the most complete open clusters sample with metallicity, age and distance data as well as kinematic information, some preliminary statistical analysis regarding the spatial and ...

Formation of Open Clusters [PDF]
Symposium - International Astronomical Union, 1980 A forming star progresses through several evolutionary stages which are marked by different observational signs that can be identified by different techniques. Stellar birth from interstellar matter occurs in dense, cold clouds of gas due to a local increase in the density and interstellar clouds composed of molecules and grains are the preferential ...

THE CHEMICAL HOMOGENEITY OF OPEN CLUSTERS [PDF]
The Astrophysical Journal, 2016 ABSTRACT Determining the level of chemical homogeneity in open clusters is of fundamental importance in the study of the evolution of star-forming clouds and that of the Galactic disk. Yet limiting the initial abundance spread in clusters has been hampered by difficulties in obtaining consistent spectroscopic abundances for different ...

Asteroseismology in Open Clusters [PDF]
International Astronomical Union Colloquium, 1995 Within two groups or networks we are trying to build the observational fundamentals for better tests of stellar evolution. The first group is STACC (Small Telescope Array with CCD Cameras) and the second the EU HCM program ANTENA (involving institutes in Spain, France and Denmark).The first information needed is photometric data.

Open clusters in Auriga OB2 [PDF]
Monthly Notices of the Royal Astronomical Society, 2016 We study the area around the H ii region Sh 2-234, including the young open cluster Stock 8, to investigate the extent and definition of the association Aur OB2 and the possible role of triggering in massive cluster formation. We obtained Strömgren and J, H, KS photometry for Stock 8 and Strömgren photometry for two other cluster candidates in the area,
