The origin of high velocity stars from Gaia and LAMOST
Cuihua Du, Hefan Li, Heidi Jo Newberg +4
Based on the second Gaia data (Gaia DR2) and spectroscopy from the LAMOST Data Release 5, we defined the high-velocity (HiVel) stars sample as those stars with $v_{\mathrm{gc}} > 0…
On the radial metallicity gradient and radial migration effect of the Galactic disk
Yunpeng Jia, Yuqin Chen, Gang Zhao +4
We study the radial metallicity gradient as a function of [Mg/Fe] and with the help of a guiding radius based on the Apache Point Observatory Galactic Evolution…
Metallicity and Kinematics of the Galactic halo from the LAMOST sample stars
Shuai Liu, Cuihua Du, Heidi Jo Newberg +8
We study the metallicity distribution and kinematic properties of 4,680 A/F/G/K-type giant stars with 5 kpc selected from the LAMOST spectroscopic survey. The metallicity di…
Giant planets around FGK stars form probably through core accretion
Wei Wang, Liang Wang, Xiang Li +2
We present a statistical study of the planet-metallicity (P-M) correlation, by comparing the 744 stars with candidate planets (SWPs) in the Kepler field which have been observed wi…
