Stellar Loci. IX. Estimation of Stellar Parameters from CSST-like Photometry
Xue Lu, Haibo Yuan, Kai Xiao +5
The China Space Station Telescope (CSST) will conduct a deep and wide imaging survey in the NUV-, u-, g-, r-, i-, z-, and y-bands. In this work, using theoretical data synthesized…
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…
Exploring Be phenomena in OBA stars: a Mid-infrared search
Mingjie Jian, Noriyuki Matsunaga, Biwei Jiang +2
As early-type stars with a rotation speed close to their critical velocity, Be stars experience an event called the Be phenomenon. The material in their equator is ejected into out…
Stellar Loci. VII. Photometric Metallicities of 5 Million FGK Stars Based on GALEX GR6+7 AIS and Gaia EDR3
Xue Lu, Haibo Yuan, Shuai Xu +5
We combine photometric data from GALEX GR6+7 AIS and Gaia EDR3 with stellar parameters from the SAGA and PASTEL catalogs to construct high-quality training samples for dwarfs ($\rm…
Photometric calibration of the Stellar Abundance and Galactic Evolution Survey (SAGES): Nanshan One-meter Wide-field Telescope g, r, and i band imaging data
Kai Xiao, Haibo Yuan, Bowen Huang +16
In this paper, a total of approximately 2.6 million dwarfs were constructed as standard stars, with an accuracy of about 0.01-0.02 mag for each band, by combining spectroscopic dat…
Stellar Loci VI: An Updated Catalog of the Best and Brightest Metal-poor Stars
Shuai Xu, Haibo Yuan, Ruoyi Zhang +3
We employ Gaia, 2MASS, and ALLWISE photometry, as well as astrometric data from Gaia, to search for relatively bright very metal-poor ([Fe/H] ; VMP) giant star candidates u…
Stellar loci IV. Red giant stars
Ruoyi Zhang, Haibo Yuan, Xiaowei Liu +3
In the fourth paper of this series, we present the metallicity-dependent Sloan Digital Sky Survey (SDSS) stellar color loci of red giant stars, using a spectroscopic sample of red…
Correction to the photometric magnitudes of the Gaia Early Data Release 3
Lin Yang, Haibo Yuan, Ruoyi Zhang +4
In this letter, we have carried out an independent validation of the Gaia EDR3 photometry using about 10,000 Landolt standard stars from Clem & Landolt (2013). Using a machine lear…
