Elemental abundances distributions in (R, ) plane with LAMOST DR5 and Gaia DR2
Xilong Liang, Jingkun Zhao, Yuqin Chen +4
Since Gaia DR2 was released, many velocity structures in the disk have been revealed such as large scale ridge-like patterns in the phase space. Both kinematic information and stel…

A Hint of Three-section Halo as Seen from the APOGEE DR14
Y. Q. Chen, G. Zhao, X. X. Xue +4
Based on the [Fe/H] versus [Mg/Fe] diagram and distances from APOGEE data release 14, we compare the spatial distributions, the l-Vlos diagram and the abundance gradients between h…
