The Next Generation Virgo Cluster Survey. XVII. A Search for Planetary Nebulae in Virgo Cluster Globular Clusters
Weijia Sun, Eric W. Peng, Youkyung Ko +11
The occurrence of planetary nebulae (PNe) in globular clusters (GCs) provides an excellent chance to study low-mass stellar evolution in a special (low-metallicity, high stellar de…
Stellar rotation bifurcation caused by tidal locking in the open cluster NGC 2287?
Weijia Sun, Chengyuan Li, Licai Deng +1
We present a detailed analysis of the projected stellar rotational velocities of the well-separated double main sequence (MS) in the young, Myr-old Milky Way open cluster…
Tidal-locking-induced stellar rotation dichotomy in the open cluster NGC 2287?
Weijia Sun, Chengyuan Li, Licai Deng +1
Stars spend most of their lifetimes on the `main sequence' (MS) in the Hertzsprung--Russell diagram. The obvious double MSs seen in the equivalent color--magnitude diagrams charact…
Extended main-sequence turnoffs in the double cluster and Persei: The complex role of stellar rotation
Chengyuan Li, Weijia Sun, Richard de Grijs +4
Using {\sl Gaia} Data Release 2 photometry, we report the detection of extended main-sequence turnoff (eMSTO) regions in the color--magnitude diagrams (CMDs) of the Myr-o…
Stellar rotation and the extended main sequence turnoff in the open cluster NGC 5822
Weijia Sun, Richard de Grijs, Licai Deng +1
The origin of extended main sequence turnoffs (eMSTOs) in intermediate-age (1-3 Gyr) clusters is one of the most intriguing questions in current star cluster research. Unlike the s…
