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…
Measuring the Diffuse Interstellar Bands at 5780, 5797, and 6614 Å in Low-Resolution Spectra of Cool Stars from LAMOST
Xiao-Xiao Ma, Jian-Jun Chen, A-Li Luo +7
We attempt to measure the DIBs 5780, 5797 and 6614 in over two million low-resolution spectra of cool stars from LAMOST. Based on the DIB measurements, the correlation bet…
Probing the distinct extinction law of the Pillars of Creation in M16 with JWST
Jun Li, Bingqiu Chen, Biwei Jiang +2
Investigating the extinction law in regions of high dust extinction, such as the Pillars of Creation within the M16 region, is crucial for understanding the densest parts of the in…
Spatial Variations of Dust Opacity and Grain Growth in Dark Clouds: L1689, L1709 and L1712
Jun Li, Biwei Jiang, He Zhao +2
The far-infrared (FIR) opacity of dust in dark clouds within the Ophiuchus molecular cloud is investigated through multi-wavelength infrared observations from UKIDSS, Spitzer and H…
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…
