【摘要】：LAMOST望远镜是我国自主创新设计和研制的世界上最大口径的大视场望远镜,也是目前世界上光谱获取率最高的望远镜.它的研制成功改变了我国在大规模光谱观测和大型天文基础观测数据方面空白的面貌.LAMOST作为国家设备向全国天文界开放,并积极开展国际合作.LAMOST致力于银河系内恒星的巡天,为开展银河系结构和演化前沿研究,精确描绘银河系,特别是银盘的星族、恒星运动和金属丰度分布,揭示银河系恒星形成和化学增丰历史,精确绘制银河系物质组成等方面研究提供了大量可靠的光谱观测数据.
[Abstract]:LAMOST telescope is the largest large field of view telescope in the world, which is designed and developed independently in China. The telescope, which has the highest spectral acquisition rate in the world at present, has successfully changed the blank features of large scale spectral observation and large astronomical basic observation data in China. The national astronomical community is open. And actively carry out international cooperation. LAMOST dedicated to the Milky way stars survey, for the development of the Milky way structure and evolution of the frontier research, accurate description of the Milky way, especially the silver disk of the stars. Star motion and metal abundance distribution reveal the history of star formation and chemical enrichment in the Milky way and provide a large number of reliable spectral observation data for accurately mapping the material composition of the Milky way.
