Stellar parameters of 18 M dwarfs

Deriving metallicities for solar-like stars follows well-established methods, but for cooler stars such as M dwarfs, the determination is much more complicated due to forests of...针对类太阳恒星的金属丰度（metallicity）推导已具备成熟可靠的方法，但对于M矮星（M dwarfs）这类低温恒星，由于谱线森林（forests of）等未完整展开的因素，其金属丰度的测定要复杂得多。
