Multiple stellar populations at less evolved stages-III: a possible helium spread in NGC 2210

Chengyuan Li, Xin Ji, Long Wang +6

Helium variations are common features of globular clusters (GCs) with multiple stellar populations. All the formation scenarios predict that secondary population stars are enhanced…

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…

Multiple stellar populations at less evolved stages: detection of chemical variations among main-sequence dwarfs in NGC 1978

Chengyuan Li, Baitian Tang, Antonino P. Milone +4

Multiple stellar populations (MPs) with different chemical compositions are not exclusive features of old GCs (older than 10 Gyr). Indeed, recent studies reveal that younger cluste…

When does the onset of multiple stellar populations in star clusters occur-III: No evidence of significant chemical variations in main-sequence stars of NGC 419

Chengyuan Li, Yue Wang, Baitian Tang +3

Recent studies have revealed that the onset age for the presence of multiple stellar populations (MPs) in star clusters seems to correspond to the disappearance of the extended mai…

New insights into the formation of the blue main sequence in NGC 1850

Yujiao Yang, Chengyuan Li, Licai Deng +2

Recent discoveries of bimodal main sequences (MSs) associated with young clusters (with ages Gyr) in the Magellanic Clouds have drawn a lot of attention. One of the pr…
