标题： A Second Luminous Blue Variable in the Quintuplet Cluster

摘要： 获得了FMM#362（银河系中心五重星团附近的一颗亮星）的H和K波段中等分辨率以及4$\mu$米高分辨率光谱。这些波段中的光谱特征与 Pistol 星（一颗明亮的蓝变星，也是已知最亮的恒星之一）的光谱特征非常吻合。新的光谱数据和之前获得的测光数据表明FMM#362具有非常高的光度L$\geq 10^6$ \Lsun 和温度范围在10,000至13,000开尔文之间。根据其光度、温度、光变特性和与Pistol星的相似性，我们得出结论：FMM#362是一颗明亮的蓝变星。 显示英文摘要

摘要： H and K band moderate resolution and 4 $\mu$m high resolution spectra have been obtained for FMM#362, a bright star in the Quintuplet Cluster near the Galactic Center. The spectral features in these bands closely match those of the Pistol Star, a luminous blue variable and one of the most luminous stars known. The new spectra and previously-obtained photometry imply a very high luminosity for FMM#362, L $\geq 10^6$ \Lsun, and a temperature of 10,000 - 13,000 K. Based on its luminosity, temperature, photometric variability, and similarities to the Pistol Star, we conclude that FMM#362 is a luminous blue variable.
