High-Priority Compact-Object Candidates in Young Clusters from the \textit{Gaia} DR3 Non-Single-Star Catalog

Dejian Liu, Kangteng Chang, Yao Huang +7

The search for massive compact objects such as black holes (BHs) or neutron stars (NSs) in star clusters is longstanding challenge in astrophysics, yet no definitive identification…

Outflowing Gas in the Planetary Nebula K 3-54

Xiuhui Chen, Dejian Liu, Ping Yan +3

As planetary nebulae (PNe) evolve, they develop slow and strong dust-driven stellar winds, making the joint study of dust and gas essential for understanding their nature. As a pil…

Kinematics of Young Stellar Objects Under Various Stellar Feedback

Longhui Yang, Dejian Liu, Chaojie Hao +6

Based on the Gaia Data Release 3 and APOGEE datasets, we investigate the kinematic differences between young stellar objects (YSOs) and their parent clouds in five nearby star-form…

A New Statistical Analysis of the Morphology of Spiral Galaxies

Junye Wei, Ye Xu, Zehao Lin +4

Morphology is the starting point for understanding galaxies. Elmegreen et al. classified spiral galaxies into flocculent, multiple-arm, and grand-design galaxies based on the regul…

Search for Classical Cepheids in Galactic Open Clusters and Calibration of the Period Wesenheit Metallicity Relation in the Gaia Bands

Huajian Wang, Ye Xu, Zehao Lin +3

It is beneficial to calibrate the period Wesenheit metallicity relation (PWZR) of Delta Cephei stars (DCEPs), i.e., classical Cepheids, using accurate parallaxes of associated open…

Unveiling the initial conditions of open star cluster formation

C. J. Hao, Y. Xu, L. G. Hou +2

Open clusters (OCs) are infrequent survivors of embedded clusters gestated in molecular clouds. Up to now, little is known about the initial conditions for the formation of OCs. He…
