TL;DR
This paper analyzes the distribution and physical characteristics of open star clusters to understand the structure of the Milky Way Galaxy, including parameters like scale height, mass density, and reddening.
Contribution
It provides a comprehensive statistical analysis of open clusters using the MWSC catalogue to derive Galactic structural parameters and explore cluster relations.
Findings
Estimated Galactic disk parameters are sensitive to cluster sample selection.
Derived scale height and local mass density of the Galactic disk.
Identified relationships between cluster mass, radius, and age.
Abstract
In 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 distribution of clusters in the Galaxy and determine the scale height, solar offset, local mass density and distribution of reddening material in the solar neighbourhood. We also explored the mass-radius and mass-age relations in the Galactic open star clusters. We find that the estimated parameters of the Galactic disk are largely influenced by the choice of cluster sample.
