Multiple populations in globular clusters and their parent galaxies
A. P. Milone, A. F. Marino, G. S. Da Costa +14
The 'chromosome map' diagram (ChM) proved a successful tool to identify and characterize multiple populations (MPs) in 59 Galactic Globular Clusters (GCs). Here, we construct ChMs…
When does the onset of multiple stellar populations in star clusters occur-II: No evidence of multiple stellar populations in Lindsay 113
Chengyuan Li, Yue Wang, Antonino P. Milone
The presence of multiple populations (MPs) in almost all globular clusters (GCs) older than ~10 Gyr, has caught lots of attention. Recently, cumulative evidence indicates that extr…
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…
When does the onset of multiple stellar populations in star clusters occur? Detection of enriched stellar populations in NGC 2121
Chengyuan Li, Richard de Grijs
Star-to-star light-element abundance variations, know as multiple stellar populations (MPs), are common in almost all Galactic globular clusters. Recently, MPs have also been detec…
