X-ray-age relation and exoplanet evaporation

We study the relationship between coronal X-ray emission and stellar age for late-type stars, and the variation of this relationship with spectral type. We select 717 stars from...本研究针对晚型恒星（late-type stars），探究其日冕X射线辐射（coronal X-ray emission）与恒星年龄（stellar age）之间的关联，以及该关联随光谱型（spectral type）的变化规律。本研究从……中选取了717颗恒星。
