LAMOST_DR11_AFGK_AI-ready_Dataset
Bing Du ; A-Li Luo ; Yi-han Song
This dataset contains 111,417 high-quality spectra for 91,542 AFGK-type stars, with stellar labels such as Teff, log g, [Fe/H], [α/M], stellar mass, and absolute G-band magnitude. It reaches a metallicity of [Fe/H] ∼ -3.8 dex, significantly below the LAMOST pipeline’s lower limit of -2.5 dex, and covers Teff≈ 3800–13000 K, log g ≈ 0.1–5.0 dex, 12[α/M] from -0.4 to 0.6 dex, mass from 0.4 to 6.0 M⊙, and MG from -4.0 to 8.0 mag.
