Open Star Clusters and Their Asymmetrical Tidal Tails [PDF]
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 ...

Dynamics of Open Star Clusters [PDF]
Symposium - International Astronomical Union, 1985 The dynamical evolution of open star clusters has been studied successfully by numerical N-body simulations. We compare in detail the theoretically predicted lifetimes with those derived from the observed age distribution of open clusters. Rare but efficient encounters between clusters and giant molecular clouds are probably responsible for the sudden ...

Non-stationarity of Open Star Clusters [PDF]
, 2021 The monograph poses issues related to the study of the non-stationarity of open star clusters (OSCs), starting with an analysis of the properties of the trajectories of individual stars to the study of collective motion of stars.

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 Galactic structure [PDF]
Proceedings of the International Astronomical Union, 2017 AbstractIn order to understand the Galactic structure, we perform a statistical analysis of the distribution of various cluster parameters based on an almost complete sample of Galactic open clusters yet available. The geometrical and physical characteristics of a large number of open clusters given in the MWSC catalogue are used to study the spatial ...

Heterogeneity of the population of open star clusters in the Galaxy [PDF]
Astronomy Letters, 2012 Based on published data, we have compiled a catalogue of fundamental astrophysical parameters for 593 open clusters of the Galaxy. In particular, the catalogue provides the Galactic orbital elements for 500 clusters, the masses, central concentrations ...

A CATALOG OF 120 NGC OPEN STAR CLUSTERS [PDF]
Journal of The Korean Astronomical Society, 2011 A sample of 145 JHK{2MASS observations of NGC open star clusters is studied, of which 132 have never been studied before. Twelve are classifled as non-open clusters and 13 are re-estimated self-consistently, after applying the same methods in order to ...
