论文摘要
在这项工作中，我们介绍了NGC 1156 Galaxy中新发现的发光蓝色变量（LBV）的频谱建模结果。使用非LTE代码CMFGEN计算扩展的大气模型。我们获得了发现的LBV $ L \ simeq（1.6 \ pm0.2）\ times 10^{6} l _ {\ odot} $，有效温度$ t _ {\ text {eff}} = 7.9 \ pm0.4 $ kk and mass-loss费率$ \ dot} （8.2 \ pm1.0）\ times 10^{ - 4} m _ {\ odot} \ text {yr}^{ - 1} $。风中的氢丰度为$ \ of20 \，金属性的$％$ z = 0.5 z _ {\ odot} $的主机银河系$。
In this work we present the spectrum modeling results for the newly discovered luminous blue variable (LBV) in the NGC 1156 galaxy. Extended atmosphere models were calculated using the non-LTE code CMFGEN. We have obtained the luminosity of the discovered LBV $L\simeq (1.6\pm0.2) \times 10^{6} L_{\odot}$, effective temperature $T_{\text{eff}}=7.9\pm0.4$ kK and mass-loss rate $\dot{M}f^{-0.5}= (8.2\pm1.0) \times 10^{-4} M_{\odot}\text{yr}^{-1}$. The hydrogen abundance in the wind is $\approx20\,$% for the metallicity $Z=0.5 Z_{\odot}$ of the host galaxy.
