At what mass are stars braked? The implication from the turnoff morphology of NGC 6819
Yong Yang, Chengyuan Li, Yang Huang +1
Extended main-sequence turnoffs apparent in most young and intermediate-age clusters (younger than ~2 Gyr) are known features caused by fast rotating early-type (earlier than F-typ…

Multiple stellar populations at less evolved stages-II: no evidence of significant helium spread among NGC 1846 dwarfs
Chengyuan Li
The detection of star-to-star chemical variations in star clusters older than 2 Gyr has changed the traditional view of star clusters as canonical examples of "simple stellar popul…

The spatial distributions of blue main-sequence stars in Magellanic Cloud star clusters
Yujiao Yang, Chengyuan Li, Richard de Grijs +1
The color-magnitude diagrams (CMDs) of young star clusters show that, particularly at ultraviolet wavelengths, their upper main sequences (MSs) bifurcate into a sequence comprising…
