Evolutionary studies of the Young Star Clusters: \\NGC 1960, NGC 2453 and NGC 2384

TL;DR

This study analyzes three young star clusters using infrared observations to determine their properties and compare their evolution, extending previous data to fainter magnitudes for better understanding of their stellar populations.

Contribution

It provides new estimates of reddening, distance, and age for NGC 1960, NGC 2453, and NGC 2384, and extends their color-magnitude diagrams to fainter magnitudes for detailed evolutionary analysis.

Findings

Estimated ages range from 31.6 to 200 Myr.

Extended luminosity functions to fainter magnitudes.

Compared cluster evolution with Lyngå 2 and NGC 1582.

Abstract

We report the analysis of the young star clusters NGC 1960, NGC 2453 and NGC 2384 observed in the $J$ (1.12 $\mu$m), $H$ (1.65 $\mu$m) and $K^{'}$ (2.2 $\mu$m) bands. Estimates of reddening, distance and age as $E(B-V)=0.25$, $d= 1380$ pc and $t=31.6$ to 125 Myr for NGC 1960, $E(B-V)=0.47$, $d=3311$ pc and $t=40$ to 200 Myr for NGC 2453 and $E(B-V)=0.25$, $d=3162$ pc and $t=55$ to 125 Myr for NGC 2384 have been obtained. Also, we have extended the color--magnitude diagrams of these clusters to the fainter end and thus extended the luminosity functions to fainter magnitudes. The evolution of the main sequence and luminosity functions of these clusters have been compared with themselves as well as Lyng\aa 2 and NGC 1582.
