摘要: We present a determination of the effective temperatures, iron abundances and microturbulent velocities for pseudo-photosphere V838 Mon on 2002 February 25, March 2 26. Physical parameters line-forming region were obtained in framework selfconsistent approach, using fits synthetic spectra to observed wavelength range 5500‐6700 A. T eff = 5330 ± 300, 5540 270 4960 190 K, 2, 26, respectively. The abundance log N (Fe) =− 4.7 does not appear change atmosphere from 25 Ke yw ords: stars: ‐ atmospheres individual: Mon.
