Stellar Spectral Interpolation using Machine Learning
Kaushal Sharma, Harinder P. Singh, Ranjan Gupta +6
Theoretical stellar spectra rely on model stellar atmospheres computed based on our understanding of the physical laws at play in the stellar interiors. These models, coupled with…
GD-1: the relic of an old metal-poor globular cluster
Guang-Wei Li, Brian Yanny, Yue Wu
Combining data from Gaia DR2, SDSS DR14 and LAMOST DR6, we update the fit to model of the properties of the stellar stream GD-1 and find that it has an age of Gyr, [Fe/H]…

Time stamps of vertical phase mixing in the Galactic disk from LAMOST-Gaia stars
Hai-Jun Tian, Chao Liu, Yue Wu +2
The perturbation mechanism of the Galactic disk has puzzled us for a long time. The imprints from perturbations provide important diagnostics on the disk formation and evolution. H…

Misclassified B stars in the Kepler field
Chunguang Zhang, Chao Liu, Yue Wu +7
Stellar fundamental parameters are important in the asteroseismic study of Kepler light curves. However, the most used estimates in the Kepler Input Catalog (KIC) are not accurate…
The extraneous eclipses on binary light curves: KIC 5255552, KIC 10091110, and KIC 11495766
J. Zhang, S. B. Qian, S. M. Wang +3
Aims. We aim to find more eclipsing multiple systems and obtain their parameters, thus increasing our understanding of multiple systems. Methods. The extraneous eclipses on the \te…
Two twin binaries with nearly identical components: KIC 4826439 and KIC 6045264
Jia Zhang, Sheng-Bang Qian, Shu-Min Wang +2
Two twin binaries, KIC 4826439 and KIC 6045264, with very similar component stars were found photometrically based on eclipsing binary light curves. The absolute…
Red Clump stars from LAMOST II: the outer disc of the Milky Way
Jun-chen Wan, Chao Liu, Li-cai Deng +1
We present stellar density maps of the Galactic outer disc with red clump stars from the LAMOST data. These samples are separated into younger (mean age ~ 2.7 Gyr) and older (mean…
Candidate members of the Pal 5, GD-1, Cetus Polar, and Orphan tidal stellar halo streams from Sdss DR9, Lamost DR3 and APOGEE catalogues
Guang-Wei Li, Brian Yanny, Hao-Tong Zhang +8
We present candidate members of the Pal 5, GD-1, Cetus Polar, and Orphan tidal stellar streams found in LAMOST DR3, SDSS DR9 and APOGEE catalogs. In LAMOST DR3, we find 20, 4, 24 h…
LAMOST Spectroscopic Survey of the Galactic Anticentre (LSS-GAC): the second release of value-added catalogues
Maosheng Xiang, Xiaowei Liu, Haibo Yuan +29
We present the second release of value-added catalogues of the LAMOST Spectroscopic Survey of the Galactic Anticentre (LSS-GAC DR2). The catalogues present values of radial velocit…
Exoplanet Orbital Eccentricities Derived From LAMOST-Kepler Analysis
Ji-Wei Xie, Subo Dong, Zhaohuan Zhu +14
The nearly circular (mean eccentricity <e>~0.06) and coplanar (mean mutual inclination <i>~3 deg) orbits of the Solar System planets motivated Kant and Laplace to put forth the hyp…
