Cool stars at the Galactic Center

We present {lambda}/{Delta}{lambda}=550-1200 near-infrared H and K spectra for a magnitude-limited sample of 79 asymptotic giant branch and cool supergiant stars in the central...

我们报道了79颗取自中心区域（原文未完整给出）、符合星等限制样本要求的渐近巨星支（asymptotic giant branch）与冷超巨星的近红外H和K波段光谱，其光谱覆盖波长范围为550至1200，且光谱分辨本领（λ/Δλ）对应此参数区间。
