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…
A Comprehensive All-Sky Catalog of 3345 Molecular Clouds from Three-dimensional Dust Extinction
Tao Wang, Haibo Yuan, Bingqiu Chen +4
Understanding the distribution and properties of molecular clouds is crucial for tracing the structure and evolution of the interstellar medium and the large-scale morphology of th…
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…
The Vertical Metallicity Gradient of the Galactic Disk for Mono-Age Stellar Populations in LAMOST
Gaohuan Long, Haibo Yuan, Shuai Xu +3
The vertical metallicity gradient of the Galactic disk offers valuable insights into the disk's formation and chemical evolution over time. We utilized the LAMOST-LRS young stellar…
The Dust Extinction Curve: Beyond R(V)
Gregory M. Green, Xiangyu Zhang, Ruoyi Zhang
The dust extinction curve is typically parameterized by a single variable, R(V), in optical and near-infrared wavelengths. R(V) controls the slope of the extinction-vs.-wavelength…
An Empirical Extinction Curve Revealed by Gaia XP Spectra and LAMOST
Ruoyi Zhang, Haibo Yuan, Bowen Huang +4
We present a direct measurement of extinction curves using corrected XP spectra of the common sources in DR3 and LAMOST DR7. Our analysis of approximately 370 thousan…
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…
A comprehensive correction of the Gaia DR3 XP spectra
Bowen Huang, Haibo Yuan, Maosheng Xiang +7
By combining spectra from the CALSPEC and NGSL, as well as spectroscopic data from the LAMOST Data Release 7 (DR7), we have analyzed and corrected the systematic errors of the Gaia…
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…
A Rv map of the Milky Way revealed by LAMOST
Ruoyi Zhang, Haibo Yuan, Bingqiu Chen
The total-to-selective extinction ratio, Rv, is a key parameter for tracing the properties of interstellar dust, as it directly determines the variation of the extinction curve wit…
Improvement of the Pan-STARRS Photometric Calibration with LAMOST and Gaia
Kai Xiao, Haibo Yuan, Bowen Huang +3
In this work, we perform the re-calibration of PS1 photometry by correcting for position-dependent systematic errors using the spectroscopy-based Stellar Color Regression method (S…
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…
Empirical temperature- and extinction-dependent extinction coefficients for the GALEX, Pan-STARRS1, Gaia, SDSS, 2MASS, and WISE passbands
Ruoyi Zhang, Haibo Yuan
We have obtained accurate dust reddening from far-ultraviolet (UV) to the mid-infrared (IR) for up to 5 million stars by the star-pair algorithm based on LAMOST stellar parameters…
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…
