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…
Formation and evolution of new primordial open cluster groups: Feedback-driven star formation
Guimei Liu, Yu Zhang, Jing Zhong +3
The formation mechanisms of open cluster (OCs) groups remain unclear due to limited sample sizes and data precision. Recent advancements in Gaia astrometric data provide an unprece…
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…
