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

银晕是银河系的重要组成部分 ,本文利用 Miller-Scalo形式的初始质量函数并结合 TSY化学演化模型 ,通过拟合晕族恒星随金属丰度的计数的观测值 。

Galactic halo is an important composition of the Galaxy. This paper calculate and discusses the chemical evolution of the early Galactic halo with Miller scalo initial mass function and TSY model by fitting the count of the halo stars with different metal abundance to observations.
