With the help of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), a team led by researchers from the National Astronomical Observatories under the Chinese Academy of Sciences (CAS) has discovered nine unevolved stars rich in lithium.

Although the mechanisms of lithium enrichment in unevolved stars remain unclear, detecting a record number of these stars could be a breakthrough in the field, as lithium is a crucial chemical element linking cosmology to the structure and evolution of stars.

LAMOST went into operation in 2008 to collect high-quality spectra data that helps astronomers study celestial bodies' chemical composition, density, atmosphere, and magnetism.
