Scientific paper

Five diffraction spectrograms of TX UMa (9 A/mm dispersion) obtained during 1980-1983 with the Special Astrophysical Observatory 6-m BTA telescope were used to determine the physical characteristics of the stellar atmospheres. The eclipsing system consists of a B8 V dwarf star and a F7 subgiant companion. Both a gas stream from the supergiant and a gas disk around the main star are observed in the system.
