Scientific paper

The far-UV as well as the UV spectrum of the spectroscopic binary system SZ Psc are studied in the wavelength ranges 1235-1950 A and 2710-3090 A. The UV spectrum of SZ Psc is mainly an emission spectrum. The short wavelength region includes emission lines formed from the low chromosphere to the transition region (e.g., Si IV, C IV, and NV) and also a deep and broad absorption line of Fe II. The Mg II(1) resonance doublet at about 2800 A presents a P Cygni profile and a multiple structure with two emission and two absorption satellite components.
