Boehm-Vitense, E. ; Dettmann, T. ; Kapranidis, S. Abstract A spectrum of Sirius B in the wavelength region 1100-1900 A taken with the IUE satellite shows an absolute flux and spectral energy distribution in the continuum in agreement with theoretical white-dwarf models with T(eff) of 26,000 K plus or minus 1000 K for log g equals 8.65 and R equals 5.08 x 10 to the 8th cm. The Lyman-alpha profile is also in agreement with these parameters. No obvious emission lines in the spectrum of Sirius B or A which could indicate the presence of a chromosphere or corona in either of the stars are observed.
