Faint stars in a faint galaxy. II. Bootes I dsph

This paper presents improved constraints on the low-mass stellar initial mass function (IMF) of the Bootes I (Boo I) ultrafaint dwarf galaxy, based on our analysis of recent...本文基于对近期相关研究的分析，对牧夫座I（Bootes I，缩写Boo I）超暗矮星系的低质量恒星初始质量函数（initial mass function，IMF）给出了改进后的约束条件。
