Lithium in Wide Binaries: Effective Temperature Governs Depletion while Rotation Plays a Minor Role
Cheng-Cheng Xie, Hai-Jun Tian, Jian-Rong Shi +1
Using a sample of 116 wide binary systems as coeval and chemically homogeneous stellar pairs, we investigate the factors governing lithium depletion in main-sequence stars. We reco…
Galactic Stellar Halo Luminosity Function
Sarah A. Bird, Chris Flynn, Rudra Sekhri +5
We measure the luminosity function (LF) of the Milky Way's stellar halo, using a magnitude complete, distance limited sample of stars from DR3. Stars with high transverse ve…
Toward High-Precision Astrometry with CSST Using Multi-Gaussian Fitting of PSF
Jialu Nie, Peng Wei, Zihuang Cao +5
The Chinese Space Station Survey Telescope (CSST) presents significant potential for high-precision astrometry. In this study, we show that the point spread function (PSF) modeled…
LAMOST Medium-Resolution Spectroscopic Survey (LAMOST-MRS): Scientific goals and survey plan
Chao Liu, Jianning Fu, Jianrong Shi +38
Since September 2018, LAMOST starts a new 5-year medium-resolution spectroscopic survey (MRS) using bright/gray nights. We present the scientific goals of LAMOST-MRS and propose a…
Properties of Radial Velocities measurement based on LAMOST-II Medium-Resolution Spectroscopic Observations
R. Wang, A. -L. Luo, J. -J. Chen +28
The radial velocity (RV) is a basic physical quantity which can be determined through Doppler shift of the spectrum of a star. The precision of RV measurement depends on the resolu…
