Sample of 45 H{alpha}EW outliers

In this work, we calibrate the relationship between H{alpha} emission and M-dwarf ages. We compile a sample of 892 M-dwarfs with H{alpha} equivalent width (H{alpha}EW)...本研究校准了Hα发射（H-alpha emission）与M型矮星（M-dwarf）年龄之间的关联。我们汇编了包含892颗带有Hα等效宽度（H-alpha equivalent width, HαEW）的M型矮星样本……
