星系是如何形成的:大规模调查时代化学丰度的大规模组装

How galaxies form: Mass assembly from chemical abundances in the era of large surveys

Rosemary F. G. Wyse

摘要:

恒星大气层中的化学丰度提供了关于恒星形成气体的独特信息,并且,对绝大多数恒星来说并不重要的模过程,例如近距离双星系统中的质量转移,在恒星的生命中是保守的。几十年来,化学和运动学之间的相关性一直被用来追踪银河系的动力学演化。我讨论它应该是如何可能的,以完善和扩展这样的分析,提供计划中的大规模深成像调查匹配光谱调查。

英文摘要:

The chemical abundances in the atmosphere of a star provide unique information about the gas from which that star formed, and, modulo processes that are not important for the vast majority of stars, such as mass transfer in close binary systems, are conserved through a star's life. Correlations between chemistry and kinematics have been used for decades to trace dynamical evolution of the Milky Way Galaxy. I discuss how it should be possible to refine and extend such analyses, provided planned large-scale deep imaging surveys have matched spectroscopic surveys.
