摘要
介绍了本星系群中最大的旋涡星系M31(仙女星系)的基本观测性质。与银河系结构类似,M31的基本成分包括:核、核球、盘和晕。对以上各个成分的观测和研究进展分别作了综述,重点是盘的星族成分和恒星形成历史,以及球状星团的分布和晕的形成历史。同时与银河系的各种观测特征和形成机制作了详细的比较。
Observational properties of the largest Local Group spiral M31(Andromeda galaxy) are presented. Similar to the Milky Way Galaxy, the main components of M31 are nucleus, bulge, disc and halo. In this paper, we have summarized the most recent observational and research progress for each component. It is concentrated on the M31 disk stellar population and star formation history, the globular clusters distribution and the halo properties. Finally, a detailed comparison for the observed values of each component and formation mechanism between M31 and our Galaxy is given.
