The Principal Parameters of Unstudied Open Clusters with NIR Observations

TL;DR

This paper determines the fundamental properties of previously unstudied open star clusters using near-infrared photometry from the 2MASS survey, providing new data on their characteristics.

Contribution

It introduces a method to derive astrometric and photometric parameters for open clusters using 2MASS data, applied to clusters lacking prior detailed analysis.

Findings

First-time determination of cluster parameters

Application of homogeneous methods to multiple clusters

Enhanced understanding of unstudied open clusters

Abstract

We studied the principal parameters of some previously unstudied open star clusters using the JHK Near-IR photometry (2MASS survey). These clusters have been selected from the updated Catalogs of Dais and Webda. Based on the 2MASS database and the DSS visual images, some homogeneous methods and algorithms have been applied. The astrometry and photometric principal parameters are determined for the first time.
