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…
Correlation between U/Th and Pb/Os abundance ratios and its application in nuclear cosmochronology
Y. Y. Huang, Q. Q. Cui, X. H. Wu +1
The abundance ratios of radioactive elements U/Th and stable elements Pb/Os from the -process are found to have a strong correlation. This correlation is quite robust with respe…
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…
