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…
The stellar parameters and elemental abundances from low-resolution spectra I: 1.2 million giants from LAMOST DR8
Zhuohan Li, Gang Zhao, Yuqin Chen +2
As a typical data-driven method, deep learning becomes a natural choice for analysing astronomical data nowadays. In this study, we built a deep convolutional neural network to est…
Kinematics of the Galactic disk from LAMOST Dwarf sample
Yingjie Jing, Cuihua Du, Jiayin Gu +10
Based on the LAMOST survey and Sloan Digital Sky Survey (SDSS), we use low-resolution spectra of 130,043 F/G-type dwarf stars to study the kinematics and metallicity properties of…
Stellar activity with LAMOST. I. Spot configuration in Pleiades
Xiang-Song Fang, Gang Zhao, Jing-Kun Zhao +2
We use the spectra of Pleiades and field stars from LAMOST DR2 archive to study how spottedness and activity vary as a function of mass at young ages. We obtained standard TiO band…
A Search for Strongly Mg-enhanced Stars from the Sloan Digital Sky Survey
Xiang Li, Gang Zhao, Yu-Qin Chen +1
Strongly Mg-enhanced stars with [Mg/Fe] 1.0 show peculiar abundance patterns and hence are of great interest for our understanding of stellar formation and chemical evolution o…
