Scientific paper

By using the INES archive of the IUE satellite, we analyzed the spectra of SS Cygni in quiescence in order to determine the value of the reddening of the binary system. The reddening of the system is reported in the literature with values that vary significantly from one another. The results demonstrate that the reddening is comprised by two components: the first, interstellar in origin, with a value E(B-V) = 0.04 ± 0.02 mag, and the second, intrinsic to the binary system, with values up to E(B-V) = 0.16 ± 0.02 mag. The intrinsic value of the reddening is variable along the quiescent phase and with orbital phase.
Based on IUE measurements, available in the INES archive.
