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 populations in low mass globular clusters: Palomar 13
Baitian Tang, Yue Wang, Ruoyun Huang +7
Since the discovery of chemically peculiar stars in globular clusters in the last century, the study of multiple populations has become increasingly important, given that chemical…
Milky Way Tomography with the SkyMapper Southern Survey. II. Photometric Re-calibration of SMSS DR2
Yang Huang, Haibo Yuan, Chengyuan Li +13
We apply the spectroscopy-based stellar-color regression (SCR) method to perform an accurate photometric re-calibration of the second data release from the SkyMapper Southern Surve…
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…
A chromosome map to unveil stellar populations with different magnesium abundances. The case of Omega Centauri
A. P. Milone, A. F. Marino, A. Renzini +7
Historically, photometry has been largely used to identify stellar populations (MPs) in Globular Clusters (GCs) by using diagrams that are based on colours and magnitudes that are…
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…
