Open star clusters and Galactic structure [PDF]
Proceedings of the International Astronomical Union, 2017 AbstractIn order to understand the Galactic structure, we perform a statistical analysis of the distribution of various cluster parameters based on an almost complete sample of Galactic open clusters yet available. The geometrical and physical characteristics of a large number of open clusters given in the MWSC catalogue are used to study the spatial ...

Variable stars in young open star clusters
Bulletin de la Société Royale des Sciences de Liège, 2018 We have carried out time series photometry of the some young open clusters NGC 1893, Be 59, NGC 7380, Stock 8 and NGC 281 to search for pre-main-sequence variable stars. We have detected several pre-main-sequence variables associated to the young open clusters with periods ranging from ~0.1 to ~50 days.

An Investigation of Open Clusters Berkeley 68 and Stock 20 Using CCD UBV and Gaia DR3 Data
The Astronomical Journal, 2023 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 complemented by space-based Gaia Data Release 3 (DR3) photometry and astrometry.

A Star Catalog for the Open Cluster NGC 188 [PDF]
Publications of the Astronomical Society of the Pacific, 2004 We present new BVRI broad-band photometry for the old open cluster NGC188 based upon analysis of 299 CCD images either obtained by us, donated by colleagues, or retrieved from public archives. We compare our results on a star-by-star basis with data from eleven previous photometric investigations of the cluster.

The Role of Binarity and Stellar Rotation in the Split Main Sequence of NGC 2422
The Astrophysical Journal, 2022 In addition to the extended main-sequence turnoffs widely found in young and intermediate-age (∼600 Myr to 2 Gyr old) star clusters, some younger clusters even exhibit split main sequences (MSs).

The Astrophysical Journal Supplement Series, 2023 Open clusters (OCs) are regarded as tracers to understand stellar evolution theory and validate stellar models. In this study, we presented a robust approach to identifying OCs.
