The Samples and Binary Fractions of Red Supergiant in M31 and M33 by the HST Observations
Min Dai, Shu Wang, Biwei Jiang +1
The binarity of red supergiants (RSGs) influences their evolution and the fate of supernovae. We investigate the binary fraction of RSGs in the Andromeda Galaxy (M31) and Triangulu…

Metallicity Distribution in M31 and M33 Based on the Tip-RGB Near-infrared Color
Ying Li, Biwei Jiang, Yi Ren
This study investigates the metallicity distribution in M31 and M33 by using the near-infrared color index of tip-red-giant-branch (TRGB) of the member stars from \cite{2021A…

The Metallicity Distribution in the LMC and the SMC based on the Tip-RGB Colors
Ying Li, Biwei Jiang, Yi Ren
The color index of tip-red giant branch (TRGB) is used to study the metallicity distribution in the Large and Small Magellanic Cloud. With the most complete and pure samp…
