Stellar masses and mass ratios for Gaia open cluster members
Sagar Malhotra, Alfred Castro-Ginard, Friedrich Anders +7
Context: Unresolved binaries in star clusters can bias stellar and cluster mass estimates, making their proper treatment essential for studying cluster dynamics and evolution. Aims…
Understanding the Planetary Formation and Evolution in Star Clusters(UPiC)-II: Catalog of planets/candidates in Open Clusters and Moving Groups
Yuan-Zhe Dai, Hui-Gen Liu, Xiaoying Pang +4
Detecting planets in open clusters offers a unique opportunity to test planet formation theories in clustered environments. The precisely determined ages of young open clusters mak…
A catalog of new blue stragglers in open clusters with Gaia DR3
Songmei Qin, Jing Zhong, Friedrich Anders +6
The high-precision {\it Gaia} data release 3 (DR3) enables the discovery of numerous open clusters in the Milky Way, providing an excellent opportunity to search for blue straggler…
Binary clusters in the Galactic disk I: Systematic identification and classification using Gaia DR3
Guimei Liu, Yu Zhang, Jing Zhong +3
Aims. We aim to identify and classify BCs using high-precision astrometric and kinematic data, and to investigate their physical properties, mutual gravitational interactions, and…
Selected open cluster sample for validating atmospheric parameters: Application to Gaia and other surveys
Tong Tang, Songmei Qin, Jing Zhong +2
Reliable stellar atmospheric parameters are essential for probing stellar structure and evolution, and for stellar population studies. However, various deviations appear in compari…
Unveiling the Binary Nature of NGC 2323
Songmei Qin, Jing Zhong, Tong Tang +9
As a well-known open cluster, NGC 2323 (also called M50) has been widely investigated for over a hundred years and has always been considered a classical single cluster. In this wo…
