Analytical Studies of NGC 2571, NGC 6802, Koposov 53 and Be 89

TL;DR

This study estimates various astrophysical parameters of four open clusters using 2MASS photometry, analyzing their stellar populations, structure, and evolutionary status.

Contribution

It provides detailed parameter estimations for four open clusters, including age, reddening, and mass functions, using comprehensive photometric analysis.

Findings

NGC 2571 is the youngest cluster with young main sequence stars.

Be 89 is identified as the oldest cluster among the four.

The study offers insights into the evolutionary stages of these clusters.

Abstract

Astrophysical parameters (age, reddening, distance, radius, luminosity function, mass function, total mass, relaxation time and mass segregation) have been estimated for open clusters NGC 2571, NGC 6802, Koposov 53 and Be 89 by using the Two Micron All Sky Survey (2MASS) photometry. We analyse the color-magnitude diagrams and stellar radial density profiles. We have found that NGC 2571 is the youngest one having young main sequence stars while Be 89 is the oldest cluster.
