Nearly 30,000 late-type main-sequence stars with stellar age from LAMOST DR5
Jiajun Zhang, Jingkun Zhao, Terry D. Oswalt +3
We construct a sample of nearly 30,000 main-sequence stars with 4500K 5000K and stellar ages estimated by the chromospheric activityage relation. This sample is u…
Most Lithium-rich Low-mass Evolved Stars Revealed as Red Clump stars by Asteroseismology and Spectroscopy
Hong-Liang Yan, Yu-Tao Zhou, Xianfei Zhang +19
Lithium has confused scientists for decades at almost each scale of the universe. Lithium-rich giants are peculiar stars with lithium abundances over model prediction. A large frac…
A new moving group in the Local Arm
Xilong Liang, Jingkun Zhao, Yuqin Chen +5
We present a new moving group clustered in kinematics, spatial position and elemental abundances. Its spatial position is around the center of the Local Arm of the Milky Way. A con…
Is NGC 5824 the Core of the Progenitor of the Cetus Stream?
Jiang Chang, Zhen Yuan, Xiang-Xiang Xue +5
A large number of new members (150) of the Cetus Stream (CS) were identified from their clustering features in dynamical space using 6D kinematic data by combining LAMOST DR5…
