Chromospheric activity-age relation

We show that there is a relationship between the age excess, defined as the difference between the stellar isochrone and chromospheric ages, and the metallicity as measured by...本研究表明，年龄超额（age excess，定义为恒星等时线（stellar isochrone）年龄与色球年龄（chromospheric ages）的差值）与通过……测得的金属丰度（metallicity）之间存在相关性。
