J-PLUS: Stellar Parameters, C, N, Mg, Ca and [α/Fe] Abundances for Two Million Stars from DR1
Lin Yang, Haibo Yuan, Maosheng Xiang +20
Context. The Javalambre Photometric Local Universe Survey (J-PLUS) has obtained precise photometry in twelve specially designed filters for large numbers of Galactic stars. Derivin…
At what mass are stars braked? The implication from the turnoff morphology of NGC 6819
Yong Yang, Chengyuan Li, Yang Huang +1
Extended main-sequence turnoffs apparent in most young and intermediate-age clusters (younger than ~2 Gyr) are known features caused by fast rotating early-type (earlier than F-typ…
Stellar Loci V: Photometric Metallicities of 27 Million FGK Stars based on Gaia Early Data Release 3
Shuai Xu, Haibo Yuan, Zexi Niu +3
We combine LAMOST DR7 spectroscopic data and Gaia EDR3 photometric data to construct high-quality giant (0.7 1.4) and dwarf (0.5 1.5) samples in the hi…
A SysTematic seaRch fOr Dual Agns in meRgINg Galaxies (ASTRO-DARING) III: results from the SDSS spectroscopic surveys
Yang-wei Zhang, Yang Huang, Jin-ming Bai +3
As the third installment in a series systematically searching dual active galactic nuclei (AGN) amongst merging galaxies, we present the results of 20 dual AGNs found by using the…
A SysTematic seaRch fOr Dual Agns in meRgINg Galaxies (ASTRO-DARING) II: first results from long-slit spectroscopic observations
Yang-wei Zhang, Yang Huang, Jin-ming Bai +3
Building a large sample of kiloparsec (kpc)-scale dual active galactic nuclei (AGNs) amongst merging galaxies is of vital importance to understand the co-evolution between host gal…
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…
Most "young" -rich stars have high masses but are actually old
Meng Zhang, Mao-Sheng Xiang, Hua-Wei Zhang +8
Recent observations have revealed a population of -element abundances enhanced giant stars with unexpected high masses (1 ) from asteroseismic analysis and spe…
Metal-Poor Stars Observed with the Southern African Large Telescope II. An Extended Sample
Joseph Zepeda, Kaitlin C. Rasmussen, Timothy C. Beers +3
We present results from high-resolution (R ) spectroscopic observations of over 200 metal-poor stars, mostly selected from the RAVE survey, using the Southern African…
Dynamically Tagged Groups of Metal-Poor Stars from the Best \& Brightest Survey
Derek Shank, Timothy C. Beers, Vinicius M. Placco +9
Orbital characteristics based on Gaia Early Data Release 3 astrometric parameters are analyzed for metal-poor stars ([Fe/H] ) compiled from the Best B…
Planets Across Space and Time (PAST). II: Catalog and Analyses of the LAMOST-Gaia-Kepler Stellar Kinematic Properties
Di-Chang Chen, Jia-Yi Yang, Ji-Wei Xie +10
The Kepler telescope has discovered over 4,000 planets (candidates) by searching ? 200,000 stars over a wide range of distance (order of kpc) in our Galaxy. Characterizing the kine…
Mapping the Galactic Disk with the LAMOST and Gaia Red Clump Sample VII: the Stellar Disk Structure Revealed by the Mono-abundance Populations
Zheng Yu, Ji Li, Bingqiu Chen +7
Using a sample of 96,201 primary red clump (RC) stars selected from the LAMOST and Gaia surveys, we investigate the stellar structure of the Galactic disk. The sample stars show tw…
Beyond spectroscopy. I. Metallicities, distances, and age estimates for over twenty million stars from SMSS DR2 and Gaia EDR3
Yang Huang, Timothy C. Beers, Christian Wolf +8
Accurate determinations of stellar parameters and distances for large complete samples of stars are keys for conducting detailed studies of the formation and evolution of our Galax…
Gaia EDR3 Parallax Zero-point Offset based on W Ursae Majoris-type Eclipsing Binaries
Fangzhou Ren, Xiaodian Chen, Huawei Zhang +3
We independently determine the zero-point offset of the Gaia early Data Release-3 (EDR3) parallaxes based on W Ursae Majoris (EW)-type eclipsing binary systems. EWs…
Absorption of massless scalar field by furry black holes in de Rham-Gabadadze-Tolley theory
Ping Li, Yang Huang, Xin-Zhou Li
We study the absorption of massless scalar field by two types furry charged black holes in de Rham-Gabadadze-Tolley (dRGT) theory. The absorption cross section is calculated in hig…
