Missing pairs in open cluster catalogs
Qingshun Hu, Yufei Cai, Caroline Soubiran +4
Open clusters (OCs) in our Galaxy can be found in pairs, possibly forming physical binaries, or in groups. These objects offer unique insights into the process of star formation an…
Star formation in the circumgalactic high-velocity cloud Complex H
Zhihong He, Wenkang Pang, Kun Wang +2
The accretion of metal-poor gas sustains galactic star formation. In the Milky Way, this process is fueled by high-velocity clouds (HVCs), yet their fundamental properties have rem…
Gaia DR3 Open Cluster Cepheids: A Unified Catalog with Calibrated Period-Age and Period-Wesenheit Relations
Shunhong Deng, Zhihong He, Anbing Ren +7
Classical Cepheids (CCs) in Galactic open clusters (OCs) provide essential observational constraints for calibrating the period-age relation (PAR) and the period-Wesenheit relation…
Census of Blue Straggler Stars in Distant Open Clusters and Maximum Fractional Mass Excess of OC BSS
Qian Cui, Zhihong He, Shunhong Deng +4
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 disc, encompass…
The disrupting and growing open cluster spiral arm patterns of the Milky Way
Xiaochen Liu, Zhihong He, Yangping Luo +1
Star clusters provide unique advantages for investigating Galactic spiral arms, particularly due to their precise ages, positions, and kinematic properties, which are further enhan…
