Stellar parameters from LAMOST MRS DR8 J/ApJS/266/40 ivo://CDS.VizieR/J/ApJS/266/40 doi:10.26093/cds/vizier/bb-8a-18 CDS Wang R. Luo A.-L. Zhang S. Ting Y.-S.

By performing a fitting with MARCS model atmospheric theoretical synthetic spectra combined with a domain-adaptation method, we estimate the fundamental stellar parameters (Teff, logg, [Fe/H], vmic, and vmac) and 11 chemical abundances for 1.38 million FGKM-type stars of the Medium-Resolution Spectroscopic Survey (MRS) from LAMOST-II DR8. The domain-adaptation method, CYCLE-STARNET, is employed to reduce the gap between observed and synthetic spectra, and the L-BFGS algorithm is used to search the best-fit synthetic spectra. By combining the Two Micron All Sky Survey photometric survey data, Gaia EDR3 parallax, and MIST isochrones, the surface gravities of the stars are constrained after estimating their bolometric luminosities. The accuracy of Teff, logg, and [Fe/H] can reach 150K, 0.11dex, and 0.15dex, evaluated by the PASTEL catalog, asteroseismic samples, and other spectroscopic surveys. The precision of these parameters and elemental abundances ([C/Fe], [Na/Fe], [Mg/Fe], [Si/Fe], [Ca/Fe], [Ti/Fe], [Cr/Fe], [Mn/Fe], [Co/Fe], [Ni/Fe], and [Cu/Fe]) is assessed by repeated observations and validated by cluster members. For spectra with signal-to-noise ratios (S/Ns) greater than 10, the precision of the three stellar parameters and elemental abundances can achieve 76K, 0.014dex, 0.096dex, and 0.04-0.15dex. For spectra with S/Ns higher than 100, the precision stabilizes at 22K, 0.006dex, 0.043dex, and 0.01-0.06dex. 2023ApJS..266...40W https://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/266/40 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to B/pastel : The PASTEL catalogue (Soubiran+, 2016-) II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003) I/345 : Gaia DR2 (Gaia Collaboration, 2018) V/156 : LAMOST DR7 catalogs (Luo+, 2019) V/154 : Sloan Digital Sky Surveys (SDSS), Release 16 (DR16) (Ahumada+, 2020) III/284 : APOGEE-2 data from DR16 (Johnsson+, 2020) I/352 : Distances to 1.47 billion stars in Gaia EDR3 (Bailer-Jones+, 2021) J/A+A/535/A30 : Abundance of 12 stars in open clusters (Carrera+, 2011) J/A+A/566/A98 : The Gaia Benchmark Stars - Library (Blanco-Cuaresma+, 2014) J/ApJS/211/2 : Revised properties of Q1-16 Kepler targets (Huber+, 2014) J/A+A/564/A133 : Gaia FGK benchmark stars: metallicity (Jofre+, 2014) J/ApJS/215/19 : APOKASC catalog of Kepler red giants (Pinsonneault+, 2014) J/A+A/577/A9 : Sc, V, Mn, and Co in Milky Way stars (Battistini+, 2015) J/A+A/582/A81 : Gaia FGK benchmark stars: abundances (Jofre+, 2015) J/ApJ/808/16 : Cannon: a new approach to determine abundances (Ness+, 2015) J/AJ/151/144 : ASPCAP weights for APOGEE chemical elements (Garcia+, 2016) J/A+A/592/A70 : Gaia FGK stars: low-metallicities candidates (Hawkins+, 2016) J/ApJS/229/30 : Revised properties of Q1-17 Kepler targets (Mathur+, 2017) J/A+A/618/A93 : Gaia DR2 open clusters in the MW (Cantat-Gaudin+, 2018) J/ApJS/239/32 : APOKASC-2 cat. of Kepler evolved stars (Pinsonneault+, 2018) J/A+A/623/A108 : Age of 269 GDR2 open clusters (Bossini+, 2019) J/ApJS/244/27 : Radial velocity measurements in LAMOST-II (Wang+, 2019) J/ApJS/245/34 : Abundances for 6 million stars from LAMOST DR5 (Xiang+, 2019) J/A+A/633/A99 : Gaia DR2 open clusters in the MW.
