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…
Double-mode RR Lyrae star -- robust distance and metallicity indicators
Shu Wang, Xiaodian Chen, Jianxing Zhang +1
RR Lyrae (RR Lyr) stars are a well-known and useful distance indicator for old stellar populations such as globular clusters and dwarf galaxies. Fundamental-mode RR Lyr (RRab) star…
The use of double-mode RR Lyrae stars as robust distance and metallicity indicators
Xiaodian Chen, Jianxing Zhang, Shu Wang +1
RR Lyrae stars are one of the primary distance indicators for old stellar populations such as globular clusters, dwarf galaxies and galaxies. Typically, fundamental-mode RR Lyr sta…
Evolved Massive Stars at Low-metallicity V. Mass-Loss Rate of Red Supergiant Stars in the Small Magellanic Cloud
Ming Yang, Alceste Z. Bonanos, Biwei Jiang +17
We assemble the most complete and clean red supergiant (RSG) sample (2,121 targets) so far in the Small Magellanic Cloud (SMC) with 53 different bands of data to study the MLR of R…
Dependence of pulsation mode of Cepheids on metallicity
Zehao Zhang, Biwei Jiang, Yi Ren +2
The Cepheid variables in SMC, LMC, the Milky Way, M33 and M31 are used to examine the dependence of pulsation mode on metallicity which was previously found in red supergiants. The…
Physical Properties of 29 sdB+dM Eclipsing Binaries in Zwicky Transient Facility
Min Dai, Xiaodian Chen, Kun Wang +3
The development of large-scale time-domain surveys provides an opportunity to study the physical properties as well as the evolutionary scenario of B-type subdwarfs (sdB) and M-typ…
