Collaborative Research: Getting the Most from LAMOST

科学家们有几个研究目标。第一个目标是“了解银河系外围某些恒星速度和方向极高的原因”。第二个目标是“发现银河系盘中恒星群的运动模式”。他们的最终目标是？寻找更多引人注目的超高速恒星，这些恒星很可能是在两颗恒星相撞时从星团中喷出的？这些超高速恒星正被抛出银河系。美国科学家将通过美国与中国合作的大天空区域多目标光纤光谱望远镜观测800万颗银河系恒星。科学家们将向公众发表演讲，交流亚洲和美国生活的异同，包括从创建成功的合作中获得的见解。访问学者将向美国学生介绍亚洲的历史、文化、语言和生活方式。超高速恒星探测范围广泛的银河系科学，包括小尺度和大尺度。HVSS的数密度、速度和恒星类型分布可以揭示我们银河系中心大质量黑洞周围的环境。计算超高速恒星的数量为中心黑洞的增长提供了线索。通过测量这些超高速恒星的轨迹，他们测量了银河系暗物质晕势的形状。

The scientists have several research goals. The first goal is ?Understanding the causes of the very high speeds and directions of some stars in the outer reaches of our Galaxy?. The second goal is ?Discovering the patters of motions of groups of stars in disk of our Galaxy?. Their final goal is ?Searching for more of the remarkable hypervelocity stars, which are probably ejected from groups of stars, when pairs of stars collide?. These hypervelocity stars are being thrown out of the galaxy. The US scientists will observe 8 million Galactic stars from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) survey, a US-China collaboration. The scientists will give the public lectures, to communicate about the similarities and differences between life in Asia and the US, including insights gained from creating a successful collaboration. Visiting scholars will give presentations for US students on Asian history, culture, language, and lifestyle. Hypervelocity stars probe of a wide range of Galactic sciences, on both small and large scales. The number density, velocity, and stellar type distributions of HVSs can reveal the environment around the massive black hole at the center of our Galaxy. Counting the number of hypervelocity stars gives clues to the growth of the central black hole. By measuring the trajectory of these hypervelocity stars, they measured the shape of dark matter halo potential of the Galaxy.
