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…
A Tale of Two Dust Disks in Our Milky Way
Ruoyi Zhang, Haibo Yuan, Bingqiu Chen +4
Cosmic dust plays a vital role in stellar and galactic formation and evolution, but its three-dimensional structure in the Milky Way has remained unclear due to insufficient precis…
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…
An Eccentric Binary with a Misaligned Circumbinary Disk
Zhecheng Hu, Wei Zhu, Fei Dai +4
We present spectroscopic and photometric observations of Bernhard-2, which was previously identified as a candidate system to host a misaligned circumbinary disk. Our spectroscopic…
