Li-rich Unevolved Stars from LAMOST-MRS

Li-rich Unevolved Stars from LAMOST-MRS

Based on the spectra from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope medium-resolution spectroscopic survey, we select a sample of 88 Li-rich unevolved star candidates. We redetermine their photospheric lithium abundances, A(Li), through the spectral synthesis method, and take the...
