The Canis Major (CMa) region is known for its prominent arc-shaped morphology, visible at multiple wavelengths. This study integrates molecular gas data with high-precision astrome…
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…
VLBI with SKA: Possible Arrays and Astrometric Science
Yingjie Li, Ye Xu, Jingjing Li +4
The next generation of very long baseline interferometry (VLBI) is stepping into the era of microarcsecond (as) astronomy, and pushing astronomy, especially astrometry, to new h…
Probing the nature of rotation in the Pleiades, Alpha Persei, and Hyades clusters
C. J. Hao, Y. Xu, L. G. Hou +5
Unraveling the internal kinematics of open clusters is crucial for understanding their formation and evolution. However, there is a dearth of research on this topic, primarily due…

We present the results of an unbiased CO/CO/CO ( = 1-0) survey in a portion of the third Galactic quadrant (TGQ): = [219.75, 229.75] and = […
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…
What Does the Milky Way Look Like?
