Spectroscopic data of TESS objects with LAMOST
Stellar parameters and magnetic activity are important for the understanding of stellar physics and dynamo theory. We have used LAMOST spectroscopic surveys to study stellar... -
Chromospheric activities from LAMOST and K2
By using the LAMOST time-domain survey data, we study stellar activities based on the H{alpha} lines for about 2000 stars in four K2 plates. Two indices, R'H{alpha} and... -
Phot. metallicity prediction of RR Lyrae stars
RR Lyrae stars are useful chemical tracers thanks to the empirical relationship between their heavy-element abundance and the shape of their light curves. However, the... -
Exoplanet host stars from LAMOST, TESS, Kepler & K2
Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) low- and medium-resolution spectroscopic surveys are important for determination of the orbital parameters and... -
Stellar parameters of M-type stars from LAMOST DR8
The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) Low Resolution Spectroscopic Survey (LRS) provides massive spectroscopic data on M-type stars, and the... -
Chemically peculiar stars CP1 & CP2 from LAMOST
In the eighth data release (DR8) of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope, more than 318,740 low-resolution stellar spectra with types from B to early F... -
SEGUE-2 updated stellar parameter pipeline
The Sloan Extension for Galactic Understanding and Exploration 2 (SEGUE-2) obtained 128,288 low-resolution spectra (R~1800) of 118,958 unique stars in the first year of the... -
Photometric metallicities of stars in SkyMapper DR2
The Milky Way's metal-poor stars are nearby ancient objects that are used to study early chemical evolution and the assembly and structure of the Milky Way. Here we present... -
The Spitzer Kepler Survey (SpiKeS) catalog
The ~200000 targets monitored for photometric variability during the Kepler prime mission include the best-studied group of stars in the sky, due both to the extensive time... -
Ages of field stars from white dwarf comp. in Gaia
We analyze 4050 wide binary star systems involving a white dwarf (WD) and usually a main-sequence (MS) star, drawn from the large sample assembled by Tian+ (2020, J/ApJS/246/4).... -
High-velocity stars in the Gal. halo from LAMOST & Gaia
In this paper, we report 591 high-velocity star candidates (HiVelSCs) selected from over 10 million spectra of Data Release 7 (DR7) of the Large Sky Area Multi-object Fiber... -
LAMOST-Kepler/K2 survey (LK-MRS) first year obs.
Phase II of the Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST)-Kepler/K2 survey (LK-MRS), initiated in 2018, aims at collecting medium-resolution spectra... -
Am stars from LAMOST DR5
The Large Sky Area Multi-Object Fibre Spectroscopic Telescope data release 5 (DR5) released more than 200,000 low-resolution spectra of early-type stars with a signal-to-noise... -
LAMOST obs. in Kepler field. II. LRS sp. from 5yrs
The LAMOST-Kepler (LK-) project was initiated to use the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) to make spectroscopic follow-up observations for the... -
IGRINS spectral library
We present a library of high-resolution (R~45000) and high signal-to-noise ratio (S/N>=200) near-infrared spectra for stars of a wide range of spectral types and luminosity... -
Models and yields of 13-120M_{sun}_ massive stars
We present a new grid of presupernova models of massive stars extending in mass between 13 and 120M_{sun}, covering four metallicities (i.e., [Fe/H]=0, -1, -2, and -3) and three... -
EA-type eclipsing binaries observed by LAMOST
About 3196 EA-type binaries (EAs) were observed by LAMOST by 2017 June 16 and their spectral types were derived. Meanwhile, the stellar atmospheric parameters of 2020 EAs were... -
Carbon stars from LAMOST using machine learning
In this work, we present a catalog of 2651 carbon stars from the fourth Data Release (DR4) of the Large Sky Area Multi-Object Fiber Spectroscopy Telescope (LAMOST). Using an... -
Revised stellar properties of Q1-17 Kepler targets
The determination of exoplanet properties and occurrence rates using Kepler data critically depends on our knowledge of the fundamental properties (such as temperature, radius,... -
K2 EPIC stellar properties for 138600 targets
