| 英文摘要 | Abstract Based on Sloan Digital Sky Survey photometric data, Gu developed a new Monte-Carlo-based method for estimating the stellar metallicity distribution functions (MDFs). This method enables a more reliable determination of MDFs compared with the conventional polynomial-based methods. In this work, MDF determined from the method are well fit by a three-Gaussian model, with peaks at [Fe/H]?=??0.68, ?1.38, and ?1.90, associated with the thick disk, the inner halo, and the outer halo, respectively. The vertical metallicity gradient within 1? |
