S-PLUS: Beyond Spectroscopy IV. Stellar Parameters and Elemental-abundance Ratios for Six Million Stars from DR4 and First Results for the Magellanic Clouds
Yang Huang, Timothy C. Beers, Kai Xiao +18
We combine narrow/medium-band filter photometry from the Southern Photometric Local Universe Survey (S-PLUS) DR4 with ultra broad-band filter photometry from Gaia EDR3 to derive fu…
Recalibration of the Landolt UBVRI Standard Stars and the Generation of 5.4 Million New UBVRI Standard Stars using LAMOST and Gaia
Bowen Huang, Haibo Yuan, Kai Xiao +1
We present an independent validation and recalibration of the Landolt 2013 (celestial equator and ) and 2016 () standard stars in the Johnson $UBV…
Stellar Loci. VIII. Photometric Metallicities for 100 Million Stars Based on Synthetic Gaia Colors
Bowen Huang, Haibo Yuan, Shuai Xu +4
We apply the stellar locus method to synthetic and colors derived from corrected Gaia BP/RP (XP) spectra to obtain precise estimates of metallicity…
A Spatial Uniformity Check of Gaia DR3 Photometry and BP/RP Spectra
Bowen Huang, Haibo Yuan, Kai Xiao
Gaia DR3 photometry and BP/RP spectra have been widely used as reference in photometric calibrations. In this work, we check the spatial uniformity of Gaia DR3 photometry and BP/RP…
