Beyond spectroscopy. II. Stellar parameters for over twenty million stars in the northern sky from SAGES DR1 and Gaia DR3
Yang Huang, Timothy C. Beers, Hai-Bo Yuan +18
We present precise photometric estimates of stellar parameters, including effective temperature, metallicity, luminosity classification, distance, and stellar age, for nearly 26 mi…
The Stellar Abundances and Galactic Evolution Survey (SAGES) -- -- I. General Description and the First Data Release (DR1)
Zhou Fan, Gang Zhao, Wei Wang +35
The Stellar Abundances and Galactic Evolution Survey (SAGES) of the northern sky is a specifically-designed multi-band photometric survey aiming to provide reliable stellar paramet…
Local Group Dwarf Galaxy Detection Limit in the CSST survey
Han Qu, Zhen Yuan, Amandine Doliva-Dolinsky +9
We predict the dwarf galaxy detection limits for the upcoming Chinese Space Station Telescope (CSST) survey that will cover 17,500 deg of the sky with a wide field of view of…
Comparisons of Different Fitting Methods for the Physical Parameters of A Star Cluster Sample of M33 with Spectroscopy and Photometry
Zhou Fan, Bingqiu Chen, Xiaoying Pang +8
Star clusters are good tracers for formation and evolution of galaxies. We compared different fitting methods by using spectra (or by combining photometry) to determine the physica…
The Ages of M31 Star Clusters: Spectral Energy Distribution Versus Color-Magnitude Diagram
Zhou Fan, Zhongmu Li, Gang Zhao
It is well-known that fitting the Color Magnitude Diagrams (CMDs) to the theoretical isochrones is the main method to determine star cluster ages. However, when the CMDs are not av…
Testing Area of the SAGE Survey
Jie Zheng, Gang Zhao, Wei Wang +4
Sky survey is one of the most important motivations to improve the astrophysics development, especially when using new photometric bands. We are performing the SAGE (Stellar Abunda…
