Wind parameters of the new LBV in NGC1156

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.
