Metallicities of 20 Million Giant Stars Based on Gaia XP spectra
Lin Yang, Haibo Yuan, Bowen Huang +8
We design an uncertainty-aware cost-sensitive neural network (UA-CSNet) to estimate metallicities from dereddened and corrected Gaia BP/RP (XP) spectra for giant stars. This method…

A star-based method for precise flux calibration of the Chinese Space Station Telescope (CSST) slitless spectroscopic survey
Lin Yang, Haibo Yuan, Fuqing Duan +5
The upcoming Chinese Space Station Telescope (CSST) slitless spectroscopic survey poses a challenge of flux calibration, which requires a large number of flux-standard stars. In th…
