Oral Presentation

Abundance Gradient in the Milky Way disk and the LAMOST Milky Way Disk Survey

Author(s): Jinliang Hou (SHAO)

Presenter: Jinliang Hou (Shanghai Astronomical Observatory, Chinese Academy of Sciences)

In this talk, I will briefly review the current observed properties of abundance gradient in the Milky Way disk. Then I will introduce the current progress of LAMOST disk survey and its role in open clusters study.
Based on LAMOST disk survey, we will get a larger sample of open clusters with more accurate age, metallicity, radial velocity and distances, which will provide new constraint for clarifying time evolution of disk abundance gradient and the theory of stellar radial migration.
