Astrophysical Parameters of the Open Cluster NGC 2509 [PDF]
Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2023 This study presents structural and fundamental astrophysical parameters of poorly studied open cluster NGC 2509. We used the third photometric and astrometric data release of the Gaia (Gaia DR3) to perform analyses.

The Distribution of Open Clusters in the Galaxy [PDF]
Frontiers in Astronomy and Space Sciences, 2021 In this work we explore the new catalog of galactic open clusters that became available recently, containing 1,750 clusters that have been re-analyzed using the Gaia DR2 catalog to determine the stellar memberships. We used the young open clusters as tracers of spiral arms and determined the spiral pattern rotation speed of the Galaxy and the ...

The Effect of Age on the Grouping of Open Clusters: The Primordial Group Hypothesis
Universe, 2022 The Primordial Group hypothesis states that only sufficiently young open clusters (OCs) can be multiple, and old OCs are essentially isolated. We tested this postulate through four different studies using a manual search of Gaia EDR3 and extensive ...

On the metallicity of open clusters [PDF]
Astronomy and Astrophysics, 2010 Metallicity is one of four free parameters typically considered when fitting isochrones to the cluster sequence. Unfortunately, this parameter is often ignored or assumed to be solar in most papers. Hence an unknown bias is introduced in the estimation of the other three cluster parameters (age, reddening and distance).

Open source clustering software [PDF]
Bioinformatics, 2004 Abstract Summary: We have implemented k-means clustering, hierarchical clustering and self-organizing maps in a single multipurpose open-source library of C routines, callable from other C and C++ programs. Using this library, we have created an improved version of Michael Eisen's well-known Cluster program for Windows, Mac OS X and ...
