The role of radial migration on tracing lithium evolution in the Galactic disk
Haopeng Zhang, Yuqin Chen, Gang Zhao +3
With the calculated guiding center radius and birth radius , we investigate the role of radial migration on the description of lithium evolution in the Gal…
Evidence for Co-rotation Origin of Super Metal Rich Stars in LAMOST-Gaia: Multiple Ridges with a Similar Slope in phi versus Lz Plane
Yuqin Chen, Gang Zhao, Haopeng Zhang
Super metal-rich (SMR) stars in the solar neighborhood are thought to be born in the inner disk and came to present location by radial migration, which is most intense at the co-ro…
Strong [OIII]λ5007 emission line compact galaxies in LAMOST DR9: Blueberries, Green Peas and Purple Grapes
Siqi Liu, A-Li Luo, Huan Yang +8
Green Pea and Blueberry galaxies are well-known for their compact size, low mass, strong emission lines and analogs to high-z Lyα emitting galaxies. In this study, 1547 strong [OII…
Radial Migration from Metallicity Gradient of Open Clusters and Outliers
Haopeng Zhang, Yuqin Chen, Gang Zhao
Radial migration is an important process in the evolution of the Galactic disk. The metallicity gradient of open clusters and its outliers provide an effective way to probe for thi…
High-α-Metal-Rich stars in the LAMOST-MRS survey and its connection with the galactic bulge
Haopeng Zhang, Yuqin Chen, Gang Zhao +6
We report the detection of a large sample of high--metal-rich stars on the low giant branch with dex in the LAMOST-MRS survey. This special group corresponds to a…
Member stars of the GD1 tidal stream from the SDSS, LAMOST and Gaia surveys
Yang Huang, Xiaowei Liu, Bingqiu Chen +5
With the photometric data from the SDSS survey, the spectroscopic data from the SDSS/SEGUE and the LAMOST surveys, and the astrometric data from the Gaia DR2, we have identified 71…
A Search for Double-peaked narrow emission line Galaxies and AGNs in the LAMOST DR1
Zhi-Xin Shi, A-Li Luo, Georges Comte +15
LAMOST has released more than two million spectra, which provide the opportunity to search for double-peaked narrow emission line (NEL) galaxies and AGNs. The double-peaked narrow-…
The LAMOST Survey of Background Quasars in the Vicinity of the Andromeda and Triangulum Galaxies -- II. Results from the Commissioning Observations and the Pilot Surveys
Zhi-Ying Huo, Xiao-Wei Liu, Mao-Sheng Xiang +68
We present new quasars discovered in the vicinity of the Andromeda and Triangulum galaxies with the LAMOST during the 2010 and 2011 observational seasons. Quasar candidates are sel…
