Astrophysical parameters of ten poorly studied open star clusters

TL;DR

This study determines fundamental astrophysical parameters for ten poorly studied open star clusters using 2MASS photometry and DSS images, providing new insights into their properties and dynamics.

Contribution

It presents the first comprehensive determination of parameters like radius, distance, age, and mass function for these clusters, and re-estimates parameters for five clusters from previous studies.

Findings

First-time parameter determination for ten clusters

Calibration of methods with re-estimation for five known clusters

Insights into cluster structure and dynamical state

Abstract

We present here the fundamental parameters of ten open star clusters, nominated from Kronberger et al. (2006) who presented some new discovered stellar groups on the basis of 2MASS photometry and DSS visual images. Star counts and photometric parameters (radius, membership, distances, color excess, age, luminosity function, mass function, total mass, and the dynamical relaxation time) have been determined for these ten clusters for the first time. In order to calibrate our procedures, the main parameters (distance, age, and color excesses) have been re-estimated for another five clusters, which are studied by Kronberger et al. (2006) as well.
