We performed detailed photometric and astrometric analyses of the open star clusters
Berkeley 68 and Stock 20. This was based on ground-based CCD UBV photometric data …

In this study, we carried out CCD UBV photometry of eight open clusters, ASCC 115,
Collinder 421, NGC 6793, NGC 7031, NGC 7039, NGC 7086, Roslund 1, Stock 21, and …

This study calculated astrophysical parameters, as well as kinematic and galactic orbital
parameters, of the open clusters NGC 1664 and NGC 6939. The work is based on CCD …

We analysed the open clusters Czernik 2 and NGC 7654 using CCD UBV photometric and
Gaia Early Data Release 3 (EDR3) photometric and astrometric data. Structural parameters …

This paper presents photometric, astrometric, and kinematic analyses of the open clusters
NGC 189, NGC 1758 and NGC 7762 based on CCD UBV photometric and Gaia Data …

Galactic star clusters are known to harbour a significant amount of binary stars, yet their role
in the dynamical evolution of the cluster as a whole is not comprehensively understood. We …

We present photometric, astrometric, and kinematic studies of the old open star clusters
NGC 1193 and NGC 1798. Both of the clusters are investigated by combining data sets from …

Archival Vilnius CCD photometric observations are presented for the heavily reddened star
cluster Melotte 105, resulting in colour-magnitude diagrams and spectral class estimates …

A detailed analysis of ground-based CCD UBV photometry and space-based Gaia Data
Release 3 (DR3) data for the open clusters King 6 and NGC 1605 was performed. Using the …

In this study, we present CCD UBV photometry of poorly studied open star clusters, Dolidze
36, NGC 6728, NGC 6800, NGC 7209, and Platais 1, located in the first and second Galactic …
