The value-added catalogue for LAMOST DR8 low-resolution spectra |
We present a value-added catalog containing stellar parameters estimated from 7.10 million low- resolution spectra for 5.16 million unique stars with SNRs higher than 10 obtained by the LAMOST Galactic spectroscopic surveys. The catalog presents values of stellar atmospheric parameters (Teff, log g, [Fe/H]/[M/H]), [α/M], [C/Fe] and [N/Fe] and 14 bands’ absolute magnitudes deduced from LAMOST spectra using the method of neural network. The spectro-photometric distance are also provided. The catalog provide 26,868 unique very metal poor star candidates ([Fe/H] ≤ −2.0). |

A spatially dependent correction of Gaia EDR3 parallax zero-point offset based on 0.3 million LAMOST DR8 giant stars |
A spatially dependent parallax zero-point correction model for Gaia EDR3 five-parameter solution in the LAMOST footprint is firstly provided with the advantage of huge number of stars in our giant sample. |

The stellar parameters and elemental abundances from low-resolution spectra I: 1.2 million giants from LAMOST DR8 |
Based on the data from LAMOST DR8, we derived stellar parameters (Teff, log g, [M/H], [α/M]) and 10 individual elemental abundances (C, N, O, Mg, Al, Si, Ca, Mn, Fe, Ni) for 1.2 million spectra corresponding to one million unique giants and sub-giants. |
