K-band spectra of stars within central 1pc of the MW

We present a metallicity analysis of 83 late-type giants within the central 1pc of the Milky Way. K-band spectroscopy of these stars was obtained with the medium spectral...本研究针对银河系中心1秒差距（pc）范围内的83颗晚型巨星（late-type giants）开展了金属丰度（metallicity）分析。上述恒星的K波段光谱学（K-band spectroscopy）数据通过中等光谱（medium spectral...）设备获取。
