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…
Searching for Galactic Red Supergiants with Gaia RVS Spectra
Zehao Zhang, Biwei Jiang, Yi Ren +2
Red supergiants (RSGs) are essential to understanding the evolution and the contribution to the interstellar medium of massive stars. However, the number of identified RSGs within…
Data-driven stellar intrinsic colors and dust reddenings for spectro-photometric data: From the blue-edge method to a machine-learning approach
He Zhao, Shu Wang, Biwei Jiang +4
Intrinsic colors (ICs) of stars are essential for the studies on both stellar physics and dust reddening. In this work, we developed an XGBoost model to predict the ICs with the at…
Modeling of Granulation in Red Supergiants in the Magellanic Clouds with the Gaussian Process Regressions
Zehao Zhang, Yi Ren, Biwei Jiang +2
The granulation of red supergiants (RSGs) in the Magellanic Clouds are systematically investigated by combining the latest RSGs samples and light curves from the Optical Gravitatio…
