Metallicity estimates of M31 globular clusters

We present a new homogeneous set of metallicity estimates based on Lick indices for the old globular clusters of the M31 galaxy. The final aim is to add homogeneous...本研究针对仙女座星系（M31）的老年球状星团（globular clusters），提出了一套基于里克指数（Lick indices）的全新同质金属丰度估算数据集。本研究的最终目标是补充同质的……
