Extinction Distributions in Nearby Star-resolved Galaxies. II. M33
Yuxi Wang, Yi Ren, Jian Gao +2
Extinction maps are essential for tracing interstellar dust and enabling accurate stellar population studies in galaxies. Here, a high-resolution extinction distribution of nearby…
An Enhanced Sample of Galactic Red Supergiants Reveals Spiral Structures
Zehao Zhang, Biwei Jiang, Yi Ren
Red supergiants (RSGs), representing a kind of massive young stellar population, have rarely been used to probe the structure of the Milky Way, mainly due to the long-standing scar…
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…
A New Approach to Identifying Red Supergiant Stars in Metal-poor Galaxies: A Case Study of NGC 6822
Zhiwen Li, Ming Yang, Biwei Jiang +1
A complete sample of red supergiant stars (RSGs) is important for studying their properties. Identifying RSGs in extragalatic field first requires removing the Galactic foreground…
