Census of Blue Straggler Stars in Distant Open Clusters and Maximum Fractional Mass Excess of Open Cluster Blue Straggler Stars

The Astronomical Journal
We identified blue straggler stars (BSSs) in 53 open clusters utilizing data from Gaia DR3. Most of these clusters are situated in the outer regions of the Galactic disk, encompassing structures such as the warp and the Outer arm.

Calibrating the Color–Magnitude Relation of M Giants by Using Open Clusters

The Astrophysical Journal Supplement Series
M giants, with their distinctive properties such as high luminosity, serve as excellent indicators for mapping the structure of the Milky Way. The distance to distant M giants can be determined by using the color–magnitude relation (CMR), which is ...

Comprehensive Analysis of NGC 6134: Structure, Dynamics, and Blue Straggler Star Candidates

The Astrophysical Journal Supplement Series
Open clusters play a critical role in the study of both stellar and Galactic evolution. We present a comprehensive analysis of the open cluster NGC 6134 using Gaia DR3 astrometric and photometric data, supplemented with multiwavelength observations from ...
