Nearby open clusters with tidal features: golden sample selection and 3D structure
Ming Xu, Xiaoting Fu, Yang Chen +5
Open clusters offer unique opportunities to study stellar dynamics and evolution under the influence of their internal gravity, the Milky Way's gravitational field, and the interac…
The Magnified Waltz: Simulating Light Curves of Binary Stars Passing through Micro-Caustics in Strong Lensing Galaxy Clusters
Wenwen Zheng, Xiaoting Fu, Yang Chen +5
Individual stars located near the caustics of galaxy clusters can undergo extreme magnification when crossing micro-caustics, rendering them observable even at cosmological distanc…
Open Cluster Dynamics under the Influence of Outflow-Ambient Interactions
Muxin Liu, Lile Wang, Xiaoting Fu +1
Stars with outflows impinging on ambient gas experience accelerations due to the gravitational feedback from the interaction morphology between the outflow and the ambient gas. Suc…
First detection of CO isotopologues in a high-redshift main-sequence galaxy: evidence of a top-heavy stellar initial mass function
Ziyi Guo, Zhi-Yu Zhang, Zhiqiang Yan +5
Recent observations and theories have presented a strong challenge to the universality of the stellar initial mass function (IMF) in extreme environments. A notable example has bee…
