Membership Determination of 45 Open Clusters Beyond 3 kpc
Qian Cui, Zhihong He, Yangping Luo +1
Context. Open clusters (OCs) are fundamental tracers for studying the structure and chemical evolution of the Galactic disc. Reliable identification of cluster members, particularl…
PMO Polaris CO survey. II. Where is the dust?
Xunchuan Liu, Bing Gang Ju, Fujun Du +10
Dust plays critical chemical and dynamical roles in the interstellar medium (ISM), but its specific association with molecular and atomic gas remains difficult to isolate. Combinin…
PMO Polaris CO survey. I. A 100 deg view of the Polaris Flare
Xunchuan Liu, Bing-Gang Ju, Fujun Du +10
Large-area CO surveys are essential for studying molecular cloud dynamics and evolution; however, most have focused on the Galactic plane, leaving high-latitude clouds less explore…
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…
A Slowly Flattening Milky Way Stellar Disk: Investigating Galactic Warping through Dynamical Orbital Inclinations of Open Clusters
Liming Peng, Zhihong He
By evaluating angular momentum directions of open cluster (OC) samples across various Galactocentric radii, we assessed their orbital plane inclinations. Our findings reveal that,…
Geometry and Kinematics of a Dancing Milky Way: Unveiling the Precession and Inclination Variation across the Galactic Plane via Open Clusters
Zhihong He
This Letter presents a study of the geometry and motion of the Galactic disk using open clusters in the Gaia era. The findings suggest that the inclination of the Galactic disk inc…
Survey for Distant Stellar Aggregates in Galactic Disk: Detecting Two Thousand Star Clusters and Candidates, along with the Dwarf Galaxy IC10
Zhihong He, Yangping Luo, Kun Wang +5
Despite having data for over 10^9 stars from Gaia, only less than 10^4 star clusters and candidates have been discovered. Particularly, distant star clusters are rarely identified,…
A Blind All-sky Search for Star Clusters in Gaia EDR3: 886 Clusters within 1.2 kpc of the Sun
Zhihong He, Kun Wang, Yangping Luo +3
Although previous searches for star clusters have been very successful, many clusters are likely still omitted, especially at high Galactic latitude regions. In this work, based on…
