Astrophysical Parameters of the Open Cluster NGC 2509
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.

Open clusters: their kinematics and metallicities [PDF]
Proceedings of the International Astronomical Union, 2007 AbstractWe review our work on Galactic open clusters in recent years, and introduce our proposed large program for the LOCS (LAMOST Open Cluster Survey). First, based on the most complete open clusters sample with metallicity, age and distance data as well as kinematic information, some preliminary statistical analysis regarding the spatial and ...

The new detection of blue straggler stars in 50 open clusters using Gaia DR3 [PDF]
A&A 672, A81 (2023), 2023 The particularly abundant presence of blue straggler stars (BSS) in Galactic open clusters offers favorable conditions for detailed studies on the statistical properties and the origin of the blue straggler population. With the help of Gaia DR3, the number of identified open clusters continuously increases, and the determination of star cluster members

The GALAH survey: verifying abundance trends in the open cluster M67 using non-LTE modelling [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Open cluster members are coeval and share the same initial bulk chemical composition. Consequently, differences in surface abundances between members of a cluster that are at different evolutionary stages can be used to study the effects of mixing and ...
