Discovery of Nine Super Li-rich Unevolved Stars from the LAMOST Survey
T. -S. Yan, J. -R. Shi, L. Wang +7
Based on the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) medium-resolution spectroscopic survey (MRS), we report the discovery of nine super Li-rich unevolve…
Stellar activity with LAMOST. III. Temporal variability pattern in Pleiades, Praesepe, and Hyades
Xiang-Song Fang, Christian Moni Bidin, Gang Zhao +2
We present the results from a systematic study of temporal variation of stellar activity in young late-type stars. We used multi-epoch LAMOST low-resolution spectra of over 300 mem…
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…
Stellar chromospheric activity and age relation from open clusters in the LAMOST Survey
Jiajun Zhang, Jingkun Zhao, Terry D. Oswalt +5
We identify member stars of more than 90 open clusters in the LAMOST survey. With the method of Fang et al.(2018), the chromospheric activity (CA) indices logR'CaK for 1091 member…
Frequent flare events on the short-period M-type eclipsing binary BX Tri
ChangQing Luo, XiaoBin. Zhang, Kun Wang +8
We present long-term, multi-color photometric monitoring and spectroscopic observations of the short-period M-type eclipsing binary BX Tri. Six flare events were recorded in 4 year…
Stellar activity with LAMOST - II. Chromospheric activity in open clusters
Xiang-Song Fang, Gang Zhao, Jing-Kun Zhao +1
We use the LAMOST spectra of member stars in Pleiades, M34, Praesepe, and Hyades to study how chromospheric activity vary as a function of mass and rotation at different age. We me…
