3.3 Science with the LAMOST
Invited Review
The regular survey of LAMOST began in September 2012 and will end
in June 2017 after the completion of 5 observation seasons. In the
first regular survey, the projects of the LAMOST Experiment for
Galactic Understanding and Exploration (LEGUE) and
the LAMOST Extra-GAlactic Survey (LEGAS) have obtained many
scientific achievements.
The LEGUE project yields a unique data set of more...

3.3 Science with the LAMOST
Invited talk
Although the majority of stars observed by LAMOST are brighter than 17th magnitude, the spectroscopic stellar parameters can be used to select more than 10,000 red giant stars in the Milky Way halo from among the more numerous foreground dwarfs. In this talk, I will discuss some efforts to use LAMOST-selected distant RGB stars to probe the merging history of the Galaxy via tidal debris in the...

3.3 Science with the LAMOST
Contributed talk
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]...

3.3 Science with the LAMOST
Contributed talk
As a milestone of ‘near-field cosmology’ to fulfill the quest for understanding galaxy formation and evolution, the LAMOST Galactic Spectroscopic Surveys have hitherto collected quality spectra of over 7.5M stars, and this number is still increasing at a rate of 1M per annum. Benefitted from this single largest spectroscopic dataset as well as data from other photometric and spectroscopic...

3.3 Science with the LAMOST
Contributed talk
The Galactic disk is the main structural component of the Milky Way, but whether there is a sub-structure of the so-called thin- and thick- disks has always been a controversial issue. Using the stellar spectra from the LAMOST Spectroscopic Survey of the Galactic Anti-center (LSS-GAC), we obtained the distributions of [α/Fe] ratios in the R-z space for about 1 800 000 disk stars from the DR4...
