银盘恒星运动学和化学丰度与银河系结构

Disk Stellar Kinematics and Abundance with the Galactic Structure

大样本的银盘恒星的运动学数据和元素丰度特征是研究银河系结构及演化,尤其是银盘形成和演化的2个重要探针。本文首先介绍了银河系的总体结构特征,然后较详细的综述了以上2个探针的重要性。对我国LAMOST项目在研究银河系结构方面,尤其是银盘的形成和演化方面的能力作了合理的分析。

A large sample of disk stellar kinematics and abundance data is the key to trace the Galactic structure and evolution,especially for the mechanisms of disk formation and evolution,In this paper,a brief introduction of the whole properties of the Milky Way Galaxy is presented,and special attentions are given to the importance of above two tracers.A proper evaluation is given to the potential abilities of the LAMOST project to the study of the Galactic structure,disk formation and evolution.
