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…
Extinction Distributions in Nearby Star-resolved Galaxies. I. M31
Yuxi Wang, Jian Gao, Yi Ren +1
An extinction distribution of the Andromeda Galaxy (M31) is constructed with member stars as tracers by fitting multiband photometric data from UKIRT/WFCAM, PS1, and Gaia DR3. The…
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…
The Star Formation History in Local Group Galaxies. I. Ten Dwarf Galaxies
Yi Ren, Biwei Jiang, Yuxi Wang +2
The star formation histories (SFHs) of galaxies provide valuable insights into galaxy evolution and stellar physics. Understanding the SFHs enables the study of chemical enrichment…
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…
Evolved Massive Stars at Low-metallicity VI. Mass-Loss Rate of Red Supergiant Stars in the Large Magellanic Cloud
Jing Wen, Jian Gao, Ming Yang +4
Mass loss is a crucial process that affects the observational properties, evolution path and fate of highly evolved stars. However, the mechanism of mass loss is still unclear, and…
