Measuring the local dark matter density with LAMOST DR5 and Gaia DR2
Rui Guo, Chao Liu, Shude Mao +3
We apply the vertical Jeans equation to the kinematics of Milky Way stars in the solar neighbourhood to measure the local dark matter density. More than 90,000 G- and K-type dwarf…
A wide star-black-hole binary system from radial-velocity measurements
Jifeng Liu, Haotong Zhang, Andrew W. Howard +52
All stellar mass black holes have hitherto been identified by X-rays emitted by gas that is accreting onto the black hole from a companion star. These systems are all binaries with…
Tracing Kinematic and Chemical Properties of Sagittarius Stream by K-Giants, M-Giants, and BHB stars
Chengqun Yang, Xiang-Xiang Xue, Jing Li +12
We characterize the kinematic and chemical properties of 3,000 Sagittarius (Sgr) stream stars, including K-giants, M-giants, and BHBs, select from SEGUE-2, LAMOST, and SDSS s…
Identifying Galactic Halo Substructure in 6D Phase-space Using 13,000 LAMOST K Giants
Chengqun Yang, Xiang-Xiang Xue, Jing Li +6
We construct a large halo K-giant sample by combining the positions, distances, radial velocities, and metallicities of over 13,000 LAMOST DR5 halo K giants with the Gaia DR2 prope…
The Origins of Young Stars in the Direction of the Leading Arm of the Magellanic Stream: Abundances, Kinematics, and Orbits
Lan Zhang, Dana I. Casetti-Dinescu, Christian Moni Bidin +6
We explore the origins of the young B-type stars found by Casetti-Dinescu et al.(2014) at the outskirts of the Milky-Way disk in the sky region of Leading Arm of the Magellanic Str…
Stellar Stream Candidates in the Solar Neighborhood Found in the LAMOST DR3 and TGAS
Xilong Liang, Jingkun Zhao, Terry D. Oswalt +3
We have cross-matched the LAMOST DR3 with the Gaia DR1 TGAS catalogs and obtained a sample of 166,827 stars with reliable kinematics. A technique based on the wavelet transform was…
