Abstract:
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, and ellipticities
for 424 clusters, the metallicities for 264 clusters, and the
relative magnesium abundances for 56 clusters. We describe the sources
of initial data and estimate the errors in the investigated
parameters. The selection effects are discussed. The chemical and
kinematical properties of the open clusters and field thin-disk stars
are shown to differ. We provide evidence for the heterogeneity of the
population of open star clusters.
