银晕

利用Miller-Scalo初始质量函数计算银晕的化学演化

Calculating the chemical evolution of galactic halo with Miller-Scalo initial mass function

探寻银晕暗物质的一个可能方案

A possible approach for search of dark material halo in Galaxy

银河系的结构主要分为核球、银盘和银晕几个组成部分。

Galaxy is composed of Galactic bulge , plate and halo .

银晕其实就是环绕在我们熟悉的白色漩涡外的星星碎片。

The stellar halo is debris that surrounds our familiar white swirl of stars .

银河系的银盘、银晕、核球的平均金属丰度为-0.2，-1.6，-0.2。

The average values of metallicity in the disk , the halo , and Galactic bulge are - 0.2 , - 1.6 , and - 0.2 dex respectively .

介绍了白矮星宇宙纪年学研究的基本原理及其在银盘、球状星团、疏散星团以及银晕年龄确定方面的应用现状。

We also describe the basic principle of white dwarf cosmochronology and its application in defining the age of the Galactic disk , globular clusters , open clusters and Galactic halo .
