Quantitative analysis of the V838 Monocerotis spectrum
We present the determination of the effective temperature, iron abundance, and microturbulent velocities for the pseudophotosphere of V838 Mon observed on February 25, March 2 and 26, 2002. Physical parameters of the line forming region were obtained in the framework of a self-consistent approach us...

| description | We present the determination of the effective temperature, iron abundance, and microturbulent velocities for the pseudophotosphere of V838 Mon observed on February 25, March 2 and 26, 2002. Physical parameters of the line forming region were obtained in the framework of a self-consistent approach using fits of synthetic spectra to observed spectra in the wavelength range 5500–6700 Å. We obtained the values of Teff 5330±150 K, 5540±150 K, and 4960±150 K for February 25, March 2, and March 26, 2002, respectively. The iron abundance logN(Fe) = −4.7 does not appear to change in the atmosphere of V838 Mon from February 25 to March 26, 2002.
