The far ultraviolet spectrum of beta Lyrae.
Abstract
The ultraviolet spectrum of beta Lyrae observed with the S 2/68 experiment aboard the TD 1 satellite has been compared with the spectra of several standard stars and with theoretical models. These results, together with those obtained by Copernicus telescope (OAO3) show that the spectrum of beta Lyrae is characterized by strong emission lines at wavelengths less than or equal to 2300 A and by absorption lines at wavelengths greater than 2300 A. The energy distribution is similar to that of a B 8 star, and the effective temperature of the models which best fit the observed energy curve is 11,000 K.
