Ba-enhanced dwarf and subgiant stars in the LAMOST Galactic surveys
Meng Zhang, Maosheng Xiang, Hua-Wei Zhang +3
Ba-enhanced stars are interesting probes of stellar astrophysics and Galactic formation history. In this work, we investigate the chemistry and kinematics for a large sample of Ba-…
The value-added catalogue for LAMOST DR8 low-resolution spectra
Chun Wang, Yang Huang, Haibo Yuan +3
We present a value-added catalog containing stellar parameters estimated from 7.10 million low-resolution spectra for 5.16 million unique stars with spectral signal-to-noise ratios…
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 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…
Stellar labels for hot stars from low-resolution spectra - I. the HotPayne method and results for 330,000 stars from LAMOST DR6
Maosheng Xiang, Hans-Walter Rix, Yuan-Sen Ting +9
We set out to determine stellar labels from low-resolution survey spectra of hot, OBA stars with effective temperature (Teff) higher than 7500K. This fills a gap in the scientific…
LAMOST J0140355+392651: An evolved cataclysmic variable donor transitioning to become an extremely low mass white dwarf
Kareem El-Badry, Eliot Quataert, Hans-Walter Rix +6
We present LAMOST J0140355+392651 (hereafter J0140), a close ( hours) binary containing a bloated, low-mass () proto-white dwarf (WD)…
