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…

New Red Supergiant Stars in the other side of our Galaxy
Lin Zhang, Bingqiu Chen, Yi Ren +3
Red supergiant stars (RSGs) are massive stars in a late stage of evolution, crucial for understanding stellar life cycles and Galactic structure. However, RSGs on the far side of o…
