Contributed talk 3.3 Science with the LAMOST 3.3 Science with the LAMOST


Dr Maosheng Xiang (NAOC)


The talk will introduce our efforts on studying the assemblage and evolution history of the Galactic disk with LAMOST. This includes a brief introduction to the LAMOST value-added catalogues, which contain robust estimates of stellar atmospheric parameters (Teff, logg, [Fe/H]), absolute magnitudes Mv, alpha-element to iron abundance ratio [a/Fe], carbon [C/H] and nitrogen abundance [N/H] yielded by LSP3, as well as interstellar extinction, distance, and kinematic parameters inferred based on the LSP3 parameters. I will then present robust stellar age estimates for millions of LAMOST stars. Finally, I will introduce scientific explorations on the stellar mass distribution, spatial structure and metallicity distribution of the Galactic disk using mono-age stellar populations from LAMOST.
